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!
