Microwave Banana Oat Cakes, Fave Banana or Oat Recipes


This post may contain affiliate links.

How has your weekend been?  Mine has gone by fast, unfortunately.  I’ve been working.

And working on household organization and decluttering projects.

And working on new recipes like this one. 

Microwave Banana Oat Cakes
(Vegan & GF)
1/2 Banana, mashed
3 Tbsp Dry Whole Rolled Oats (info about Oats & Buying Certified Gluten Free is here)
1 Tbsp Brown Sugar (omit or reduce, use white sugar, or use stevia, if desired)
1 Tsp Cinnamon (or use pumpkin pie spice)

Optional: 1/2 Tbsp Chia Seeds (or use ground flax, or omit)
Optional: 1 Tbsp Dried Coconut Flakes
Optional: 1 Tbsp Cocoa Powder for Chocolate Banana Oat Cakes

Yields 1 oat cake but you can double the above recipe and microwave half the mixture in one bowl, half the mixture in another bowl, for 2 oat cakes

Mixed up batter of Microwave Banana Oat Cakes

Spray down a clean bowl or dish with cooking spray or nonstick spray.  

Transfer the mixture into the sprayed bowl and microwave for 90 seconds.

Remove from the microwave and just wait a minute or two for it to cool and firm up a bit.
And then, it will pop right out.

Or you can get fancy and invert it onto another plate.  Let’s see how many dishes we can dirty, right?

Get your fork and dig in.  Or in Skylar’s case, she eats these like cookies and skips using silverware and plates.  Which is perfect if you’re driving, on the go, or want to save on dishes.

If peanut butter isn’t your thing, try topping your Banana Oat Cake with Almond Butter, Maple Syrup, Jelly, Jam, Hot Mustard.  Kidding.  Or just plain.

If the microwave isn’t your thing, and as I’ve discussed, it’s a Tool for me, but you could cook these in a non-stick skillet for about 2 minutes per side. 

But I’m busy, and this is a snack and truth be told, I will never fire up my stovetop just to make a snack.  So I use the microwave.

I’ve seen everyone from Mama Pea to Ashley to Susan make their own versions so I thought it was high time I tried my own.  

These are portable, fast and easy (I can mash a banana and add the other ingredients in 90 secs + 90 more secs to nuke = 3 minute snack).  They hold together and are mildly sweet, warm, comforting, and a hit with Skylar.  

That’s her DSLR.  She’s practicing with the f-stop settings.

From my earlier post, glad you enjoyed my Pineapple Tips and Other Random Tips.  Thanks for sharing your food, recipe, workout, and life tips with me.  I love learning new things and many of you also told me you check to see if pineapples are ripe by tugging on one of the leaves and seeing if it releases easily or not as a sign of ripeness.

1. Best Thing You’ve Done or Ate this weekend?
Yesterday I said it was my reorganizing project that I did, but today I’m gonna go with the Banana Oat Cakes.   And the great workout I had that involved a walk outdoors with the fam.

2. What is your fave way to eat Bananas?   If you need recipes that Use up Ripe Bananas, I have Ripe Banana Recipes

I like bananas in things much more than by themselves.  Like in cake.

3.  What is your fave way to eat Oats?   If you need recipes that call for oats or are looking to put a new spin on your oats, I have Oats & Oatmeal Recipes

I like to eat oats in snacks like Vegan Peanut Butter Chocolate Chip Protein Bars which are similar in many ways to the recipe I posted today but makes bars, not cakes.  And uses the freezer, not the microwave.  But variations on a theme I’d say.  And you can omit the protein powder, too.  They still “work” without it.

I hope you have a great week, everyone.  See you tomorrow!

  1. Non of your “granola” bar recipes have caloric info? Would love to make my own, but don’t want them to be tons of fats or calories!

  2. I just have some questions:

    Am I right that I can make a bigger Microwave Cake than the picture shown?

    Am I right that the ingredients and procedures provided is ‘only’ applicable to one small bowl?

    If I can make bigger, should I double or triple the quantities of ingredients needed?


    1. If you’re making a larger batch, you need to use a larger bowl and if you double 1 ingredient you have to double all of them. I would make the recipe as written the first time until you get the hang of it and then play around from there.

      1. Thank you for answering.

        I can’t cook nor bake but I’ll my best doing this simple recipe for my family.

        :) :) :) :)

  3. Is the amount of sugar correct (1 Tablespoon), 1Tbsp of sugar is the daily recommended limit for adults. If so – I don’t think that this is a healthy food choice – Way Too Much Sugar. I can understand children liking them, they have more sugar than most candy bars.

  4. I know this is kind of an old post, but I just wanted to say thank you for this recipe :D It’s so simple, and as I’m living in a freshman dorm right now with literally just a microwave, simple is exactly what I need.

  5. These look awesome! I know in the description you said if we wanted to double it to make it in two separate bowls, but if I do want to double the ingredients, can I make it in one bowl?
