Microwave Blueberry Banana Oat Cakes

This recipe is a spinoff of my Biggie Microwave Banana Oat Cakes

And my Microwave Banana Oat Cakes recipe

But with blueberries.  

Mmmm, I love blueberries!

Microwave Blueberry Banana Oat Cakes



Microwave Blueberry Banana Oat Cakes


1 ripe medium or large banana, mashed

1/2 c dry oats (or a little more if you have an especially big banana)

1/4 c brown sugar (reduce as desired, or omit entirely, or replace with stevia)

1 Tsp Cinnamon (more if you love it)

1/4 c blueberries (frozen or fresh)

Optional: Dash of Vanilla Extract, 1 Tbsp of Chia Seeds, 1 Tbsp of Coconut Flakes, 2 Tbsp of Cocoa Powder for a chocolate banana cake


Mash the banana

Add everything else except the blueberries and stir to combine.

Then, gently fold in the blueberries.

Spray a clean bowl with cooking spray and put the batter in it

Microwave for 3.5 to 4.5 minutes.  You will know when it’s done because it will not be “juicy” looking anymore and it may have some “holes” on the surface.

After mircowaving, allow to rest for a couple minutes.  Eat in that bowl or easily invert/remove from bowl and re-plate it, or take as a to-go snack.

Top with more blueberries, syrup, jelly, agave, nut butter, raisins, nuts, seeds, dried fruit, or nothing.

This is a fast breakfast or portable snack-cake.  Wrap it up and take it with you if you’re in a hurry.

Just be careful of all that blueberry juice staining your hands if you don’t use a fork.  There are worse problems to have, though.

You could top this with syrup.  Or blueberry syrup. How good would that be!Microwave Blueberry Banana Oat Cakes with slice taken out on plate with fork

Or just eat plain like I did.

Except Skylar took the bigger half and devoured most of it in record time.  Blueberry stained fingers and all!

From my last post on Fun & Productive, it was good to hear what you’ve done this weekend that’s been fun.  Or productive.  Or both.

Another take on blueberries + oats are these Muffins: Blueberry Streusel Muffins (Vegan and GF).

Baking rather than microwaving.

Blueberry Streusel Muffins

One bowl and a spoon, no mixer required.  Nothing fancy or complicated about this recipe.

Someone always comment that they either don’t have a microwave or hate it.  So you can use the oven for these.

1. Best thing you’ve ate or done over the weekend?

Spending time with Scott and Skylar and splitting a blueberry banana oat cake.

2. Any Valentine’s Day plans?


3. Do you like blueberries?

I love blueberries!  They are so expensive to buy out of season (and really, how long is blueberry “season”) but Trader Joe’s has decent prices on fresh year round.  Of course, all stores have frozen berries year round.

4. Fresh or Frozen?  What do you use and when?

I never use fresh berries or fresh fruit in recipes unless it’s over-ripe or needs to be used up.

I bake, cook, or blend (smoothies) with frozen produce.

I save the fresh for eating!

Happy Valentine’s Day everyone!

  1. I love this!! i dont like eating bananas or eating breakfast and this is a great combo of the two! I can’t wait to try it!!

  2. I had a banana and blueberries, both that we’re getting to be old looking so just googled the internet for something to make for breakfast in the microwave using these ingredients. This was EXCEPTIONAL!!!!!! It tastes so good and all the other ingredients were basic. I was surprised I didn’t need to add any other liquid. Best internet recipe I’ve come across!!!! Thanks for posting it!

    1. Thanks for trying the recipe and I’m glad it came out great for you and that it’s the best internet recipe you’ve come across!!

  3. My daughter and I just made these and they are AMAZING! Our blueberries exploded more than yours but it made a delicious “sauce” spread throughout the cake. This is going to be bookmarked and made over and over again! Next time I am thinking chocolate chips? hehe! Thanks so much!

  4. y’all. I realize this recipe was posted three years ago but it is so, so, so ridiculously good. I have had it two mornings in a row now. instead of brown sugar I’ve been doing a little drizzle of honey, which has turned out wonderfully, then I’ve topped it straight out of the microwave with some slivered almonds and nutella (yikes). I can see myself eating this for a long time to come – I mash the banana in the same bowl that I mix all the ingredients and microwave it in, and this recipe is so forgiving to just ‘eyeballing’ the ingredients. I want to eat another serving. dang.

    1. Thanks for trying this recipe and yes it’s an oldie but I keep it up because people still find it and tend to love it and I’m glad you’re one of them!

  5. Made this for my breakfast this morning, was so good! Didn’t use any sugar but added a small drizzle of honey instead and was still deliciously sweet!

  6. I made this recipe this morning and I love the blueberries and cinnamon oatmeal combination. I did use much less than a 1/4 cup of brown sugar though as I was worried about it being too sweet with the 2 fruits in it. Turned out delicious.

  7. This looks so healthy and delicious! I’m adding it to a round up of Weight Watchers friendly blueberry recipes I’m posting on Sunday!

  8. I just stumbled upon your blog, and I must say I am an instant fan! Cannot wait to go home and try these! Every morning I take 1/2C oatmeal and 1C water in micro for 2 min, then I add chia seeds, 1/2C bluberries and one square of dark chocolate! Gets me strait through the morning!

    1. Old fashioned but quick cooking will work if that’s all you have; I prefer old-fashioned because it’s chewier. If using quick cooking, you may need to reduce cooking times, possibly – but haven’t tried it that way!

  9. I wanted to replace the frozen blueberries with fresh pomegranate….wanted to check if this would spoil the recipe or make it sour? plus i wont be adding the sugar…so will it still be sweet?>

    Appreciate your kind reply.



    1. Taste the batter and see – if it’s sour, sweeten it to taste with something you like to use if you don’t use sugar.

  10. I just made one of these and it was INCREDIBLE!!! I used a packet of maple brown sugar oatmeal, the banana, added a little bit more brown sugar, lots of cinnamon, blackberries, and raisins. Oh. My. Goodness. So good! I can see how these would be great for on the go – they stick together so well! Yummm!!! Seriously, so delicious!

    1. So glad you loved it, Kelly. Thanks for the glowing report and write back and LMK if you make other variations!

    1. They’re so easy, too. I have a 5 year old and this is an easy one…sometimes I’ll make a huge one and save half for later on in the day or one for an after school snack and half for part of her breakfast the next morning with other things. LMK how it goes!

  11. Eating this as I type! Quick and easy breakfast or yummy snack. Mine is a bit too sweet…used less than 1/4 cup brown sugar but will try less next time!

      1. Well, err, having wolfed down the whole lot in the last couple of hours I can say they are excellent!

        I like the idea of varying the amount of sugar to a teaspoon or so, since I don’t like things too sweet.

        My oat cakes weren’t as brown as yours though, so maybe I needed a riper banana, or perhaps longer in the microwave?

        I wonder if I could grill them a little for added crunch?

        Thanks again! :-)

      2. so maybe I needed a riper banana, or perhaps longer in the microwave? <-- perhaps either or both or brown sugar maybe. I wonder if I could grill them a little for added crunch? <--- probably. I don't have a grill (or time!) for that with these but if you do have either, try it!

  12. I made this for breakfast this morning and was so impressed with the results. It was such a nice change of pace from your regular bowl of oatmeal. Another plus is that it smelled up the kitchen so nice! Thank you, Averie :)

  13. The Internet is like alcohol in some sense. It accentuates what you would do anyway. If you want to be a loner, you can be more alone. If you want to connect, it makes it easier to connect.

  14. Whoa, these look incredible. I’ll have to get up a little early tomorrow and give them a try. I just bought my first pint of fresh blueberries so now I know how to use them.

  15. I just discovered your blog through the Healthy Exposures blog and I love it already! I love the pictures and the fact that there is an easy, healthy recipe that you can use the microwave for :) I am SO trying it for breakfast tomorrow!

  16. LOVE this!! Definitely should have remembered your banana version during vegan week. Now that I’m stuck to cooking with one hand, this may be one that I can try ;) Thank you for the wonderful comment on my last post. It’s the support that keeps me so upbeat!! xoxo

  17. Blueberries stained fingers are all part of the fun :)

    Best thing I ate: home made gluten free brownies with vanilla ice cream. Yum! The rest of the family had ice cream cake, so my dessert was pretty close ;)

    Valentine’s day plans: hubby is cooking a special meal and we will eat by candle light, then snuggle by the fire :)

    LOVE blueberries. So yummy. So versatile. Fresh, frozen, whole, blended, on their own, on something, in something. Always good.

    I use fresh when it is available and in season (cheaper). I use frozen almost any other time. I also buy more fresh berries than I need when they are in season, and freeze for later. Also enjoy buying over ripe bananas and freezing them for baking or soft serve.

  18. aw man!! totally regret just eating breakfast 20 minutes ago!!!!! i LOVE blueberries.. but i think they taste SO much better when they are cooked into things.. pancakes, muffins, oat cakes etc!

  19. Same here, I love that you link . especially that I am new to your blog. This way I can find all the goodness of this blog.
    And recipe from here is a definite need to try.

  20. I LOOOOOOOVE blueberries!! One of my favorite recipes is a smoothie with a base of banana, blueberries, and almond butter. Sounds kinda strange but it is REALLY good!

    Happy V Day!!

  21. Ahh, awesome!! I’m definitely going to have to break my baked-oatmeal kick and rock the microwave next time ;) I can’t believe there’s no liquid in the cake…only mashed banana?? Love it!

  22. that’s one of the major reasons why i <3 tjs so much is because of the consistent great prices! you know that no matter what the season you can usually go in and get a great deal on something :) enjoy your night lady!

  23. This looks delicious, though I may cut the sugar down a bit for my tastes. I have a microwave that’s been broken for months, but I’ve been seeing so many wonderful microwaveable breakfast treats in blog world lately that I think I’m going to have to get on the ball and get it replaced!

    I love fresh blueberries in my cereal, oats, and yogurt parfaits…or by the handful! ;) I only use frozen ones for my green smoothies.

    1. I just edited the post b/c everyone’s been commenting about the sugar…reduce, omit, use stevia, etc as desired :)

      Not essential to keep it sweet…i just like it that way :)

      thanks for saying hi!

  24. YUM! I love blueberries and warm things for breakfast that resemble cake ;) What a fun idea and a super quick breakfast!

    After my 21 day cleanse I will be trying this bad boy ;)


  25. Ah – adding blueberries – genius! I’ve been loving these as a little snack lately. Like a banana scramble but much quicker :) I LOVE blueberries, especially come summer when I can pick them myself.
    Those streusel muffins look amazing, too! Will have to check out that recipe.
    Aaand – you are one of my giveaway winners! Just E-mail me with what you would like when you get an idea :)

  26. Deliciousness!!! I love blueberries too. And in anything cooked- they explode! So so yummy. Best thing I did this weekend? Spend time with Josh on his birthday. Best thing I ate? Almond butter cookies :) Valentine’s day plan? Nothing really- low key. Hanging out with Josh and making us a nice dinner when we’re both done with work.

  27. Do you know HOW many times I have forgotten that blueberries stain?!

    Really…how hard is it to remember…lol

    I prefer to use frozen…they’re easier to work with.

    My husband and I went to a marriage conference through Family Life..it was amazing :) We’re so thankful for our church :)

  28. ive been on quite a bloob kick lately! frozen all the way, i live in a place with 4 seasons so our natural one is quite short! happy vtines!

  29. The pictures in this post are gorgeous! And those blueberry cakes look sooo good. I need to try making them without sugar (sadly, I am definitely super sugar-sensitive, boo! you are so lucky sugar is not a problem) with maybe some stevia. I will likely replace sugar with some ground up chia seeds to make up for the volume of sugar missing.

    Happy Valentine’s!

    1. I just edited the recipe and you really dont need to “replace” with anything…just cook a little longer, add a pinch more oats, b/c this recipe isnt a precise & exact science or anything :)

  30. I also discovered that using frozen blueberries in recipes yields a MUCH better (and prettier!) result than fresh! For example, in baking muffins, you get to squeeze in a zillion more berries using frozen because Trader Joe’s organic frozen blueberries are teeny-teeny-tiny. Using frozen also results in that wonderful diner/bakery-style, stained-the-wrapper-blue muffin that fresh just doesn’t seem to do. I also wanted to mention how much I appreciate that you link back to old posts, discussions, and recipes. It’s extremely helpful for times when I need to catch up and saves a lot of time — thanks for always doing that!

    1. thanks for the info on blueberries and your thoughts

      “I also wanted to mention how much I appreciate that you link back to old posts, discussions, and recipes. It’s extremely helpful for times when I need to catch up and saves a lot of time — thanks for always doing that!”—
      And thanks for saying that. Some ppl write to me telling me i link back too much, they hate it, blah blah…so it’s nice to hear someone like it :)

  31. blueberries = love. this looks delicious!

    My husband and I are celebrating Valentine’s day today — we had breakfast in bed, watched a movie, and are eating lots of home baked goodies while snuggled up reading together. He has some sort of surprise to take me to tonight, supposedly low key and quiet. Perfect way to end the weekend.

    1. Low key and quiet….how that sounds deeeelightful! We have three young girls (8 and under)…a constant circus around my house :)

  32. YUM!! I have to make these!! they look SOOOO good!!
    I love fresh fruit!! and recently got a dehydrator and decided.. fresh fruit is best. But I use frozen fruit for my protein shakes and smoothies. My favorite are raspberries.. they are cheaper to buy frozen anyway..
    I love your blog! Thank you so much for your recipes and inspiration!!

  33. I made some pretty delicious cupcakes for Valentines Day. Post to come tomorrow :) I like fresh and frozen fruit, it depends what I am using it for. Frozen for smoothies for sure!

  34. Hi Averie! After reading your blog for several months now daily, I decided to finally tell you how much I enjoy it! I love your honesty, creativity, and kindness. Your recipes are yummy to boot! I have made the kale chips several times now and they get devoured by my family as well! I love your thoughts on food allergies as well – I have celiac and haven’t eaten gluten for at least ten years. It was challenging at first, but now it is just my lifestyle, and the way I need to eat to be healthy for my body. That is difficult to explain to people sometimes who cannot even begin to imagine what life would be like without their cereal, bagel, or sugar-packed muffin in the morning! I don’t feel like I am missing out at all, and this site has helped to me explore new treats – like your raw date/cashew chews – yum-o!

    Recently, I have been breaking out on my forehead like never before. I’m 23 and went to see my skin doctor who told me to stop eating dairy. I guzzle milk, and love cheese, so this has been very hard for me. Any suggestions? I am already 100% gluten free, and eat very little-to-no meat or sea food. I do love scallops when out to dinner, egg whites all the time, and skim milk. I have been 3-days without the dairy and it is hard!! I guess I have got to focus on what I CAN have and not on what’s absent! I would like to try the vegan diet but giving up these last few pleasures is proving challenging! Tonight I am planning to make some bean burgers, we’ll see how that goes! Have a lovely rest of your weekend in sunny california and keep up the great posts!
    ps- I GROW my own blueberries and raspberries, can’t wait until the season starts!

    1. google the word

      it’s the protein in milk (casein) that has an opiate-like (morphins) quality rendering people truly addicted to dairy. Once you get past the initial stages it will get way easier to stay away from dairy if you choose to.

      I think your doctor is onto something…worth a try to see how it goes.

      Thanks for reading and delurking.

  35. I’m with you… frozen berries are for recipes and baking for sure! Can’t waste my precious fresh ones! :)

  36. I adore blueberries….it’s a family tradition here to pick our own! Every July 4th weekend we go visit my grandparents in SC and go to a local blueberry farm and spend a couple of hours picking(and ahem…eating). Then we freeze them in gallon bags to last us the whole year!

    We first went when I was probably 10 years old and the blueberries bushes(trees?) were only about knee height and I remember crouching to pick them….Now they’re well over my head…I’d bet at least 8-9 feet tall.

  37. I love blueberries so much! But like you I buy frozen when they’re not in season because they are usually way too expensive.
    Another reason why I can’t wait for summer, berry season :)

  38. Yum, another great oat recipe! Great pictures and this looks very fast and simple.

    1. Went for a long run and shopped at Whole Foods.
    2. Going out to eat with hubby and a small gift exchange.
    3. Sure, I’m always adding them to oatmeal and smoothies.
    4. Both, fresh for snacking and frozen for smoothies and recipes.

  39. I buy frozen berries, and I freeze my bananas (when they are getting really ripe) … I use these in smoothies, or soft serve. I also buy fresh berries, and use them in oatmeal, or yogurt, or to eat plain.

  40. How did you know that I just bought blueberries (on sale for 1.50!), bananas and oats yesterday? I think I will be making oat cakes.

  41. YUM – I love blueberries. I’ll be really happy to see fresh back in the store at a reasonable price again. been using frozen. For some things they are just fine, but for others, fresh is a must. I’ll definitely be happy to see fresh strawberries back in season – frozen or horrible unless beings pureed. Hope you’re having a good Sunday so far!

  42. How many cakes does the microwave blueberry oat cakes recipe make?? Did I miss it? Based on the ingredients…1 banana, 1/2 cup oats…I would say 1 but 1/4 cup brown sugar is a lot of sugar for just 1 cake?? Help!

    1. You sound panicked!

      You dont have to add sugar. Or can add less.

      And it makes 1 big cake. Or two smaller ones. The photos I used is what it makes.

  43. I love adding blueberries (fresh) to everything or just grab a handful on the go. I use frozen for berry smoothies. We went for dinner and drinks last night and are going to winterfest today! Have a great vday!

  44. OMG!!!! LOVE your site re-design. Amazing job girl, all of it. So clean, pretty & easy to navigate. Love the pic of you on the sidebar. Way to go! These oat cakes look great & I can see you are using your new camera too! xxoo

    1. Thanks, Marla, for the kind words! I love my site re-design (and yours too!) and my new camera..I seriously want your lens. So close to just buying it. We HAVE to get together…seriously…for some girltime!

  45. Best thing I did this weekend was get outside and walk with my hubby and the dog it was a glorious 30 degrees. Far from the california weather you enjoy but it was nice to finally get out and get some fresh air! Planning on walking again today.
    No plans for Valentines day! The husband works out of town so he will be gone tomorrow the spending time today will be our valentines together.
    I love blueberries and like to get a big container of fresh at costco and eat them all myself. yummy!
    I never thing to buy frozen to make with it has always been fresh for me. I do buy frozen when I think about making smoothies. I have been trying to eat more fruit so that is why I have been buys fresh!
    Love the cookie with definately need to try it. I enjoy alot of your treats last night I made the protein bars. SO YUmmy!
    I enjoy reading your blog very much!

  46. I am generally a lurker around here. However I have to say, I was going to make banana bread this am because I had 3 bananas that needed to be baked. So I tripled this recipe, used a bit of vanilla, and tossed in a scoop of chia seeds, I baked it at 350 for about 25 minutes. Delicious! Will definitely be making again!

    1. Thanks for lmk that the recipe came in handy! Your creation sounds wonderful! :) and thanks for delurking!

  47. This will be so helpful in college! Haha I will have to learn to love the microwave:)

    Best thing I had this weekend was DEFINITELY the chocolate milkshake I made! Ahhh so good!

  48. Yum — and I just bought some blueberries the other day. Perfect!

    I usually buy frozen fruit for recipes, only because to me it tastes better than fresh in stuff like muffins or breads. I’m not sure why that is? But I like fresh in oatmeal or just a handful as a snack.

    Best thing about the weekend? Going to my niece’s bday party last night, we had a great time!

  49. YUMMY!! I LOVE your banana oat cakes as you know already! :P So these look even BETTER!! You can’t beat the blueberry+banana combo…genius girl! :D

  50. OOOH those oat cakes look fabulous! And I’m loving Skylar’s pants :D

    Best thing I’ve done = work on a collage with Suave.
