Dark and fudgy Chocolate Banana Brownie Cookies made with oat flour and cacao powder for a rich and indulgent breakfast cookie that tastes just like the dessert! These healthy chocolate banana cookies are gluten-free, sugar-free and are a great freezer-friendly snack too.
Jump to RecipeI was in half the mind of not posting this recipe because the cookies didn’t look pretty at all!
Thin, an ugly top, and weirdly shaped too.
But they tasted so on point!
Cookies that taste like a rich and dark fudgy brownie need to be shared. They even had that “leave them out and they will taste better tomorrow” thing about them.
I left them as is on the counter-top after baking and had them the next day. Such intense chocolatey-ness, I cannot!
Ingredients for Fudgy Chocolate Banana Brownie Cookies
These healthy chocolate oat banana cookies are made with just a few simple ingredients you probably already have in your pantry if you’re a gluten-free baker.
- Banana: Use the ripe extremely spotty ones so they’re sweet enough that you don’t need to add any sweetener.
- Cacao Powder for an extra rich chocolate flavor, or even unsweetened Cocoa powder
- Oat Flour. You can also make your own using Rolled or Instant/Quick oats for these banana oat cookies, use the gluten-free ones if you need.
- 1:1 Sugar-free Sugar Substitute – I used Lakanto to make these no-sugar brownie cookies, but an equal amount or regular sugar would work.
- Creamy Peanut Butter
- Egg: Use a flax egg for a Vegan version.
- Vanilla Extract
- Baking Soda
Feel free to turn these into double chocolate banana cookies by adding some chocolate chips or chopped chocolate chunks on top. I’d recommend sticking to the sugar free ones here.
How to make Gluten Free Chocolate Banana Cookies
These easy chocolate banana oatmeal cookies can be made in just one bowl!
- In a large bowl, mash the bananas with the back of a fork, and then puree with a hand mixer or blender to get them completely mashed!
- Add in the wet ingredients: egg, peanut butter and vanilla, and whisk
- Sift in all the dry ingredients to the bowl: cacao or cocoa powder, oat flour and baking soda
- Mix by stirring it with a spoon. The mix will be quite liquidy,
Taste the cookie dough and see if you need add more sweetener (in case your banana was not completely ripe) - Cover the bowl with plastic wrap and place in the fridge to chill for overnight or for at least 4 hours.
To bake them:
- Preheat the oven to 350°F
- Line a baking/cookie sheet with parchment paper
- Scoop out about 2 tablespoons of the mixture at a time, drop them onto the sheet and roughly spread to shape.
Add on some chocolate chips or chopped chocolate chunks if you’d like.
- Bake for 10 minutes
LET THEM COOL!
Yes, it will be tempting to bite into these brownie cookies just fresh, but let them cool a bit.
Tips for these Chocolate Banana Oatmeal Cookies
This soft chocolate banana cookie recipe is super easy, but there are a few things you need to keep in
- Use extremely overripe bananas to make these chocolate cookies so that they’re sweet enough that you don’t need to add as much sweetener.
- Make sure the banana is completely mashed before you add everything else into the bowl. These are one bowl oatmeal cookies, so you want everything mixed in well.
- Let the banana cookie dough chill in the fridge so you can easily spoon it out into cookies.
- Shape the cookies on the baking sheet as you want, because they won’t spread too much normal ones.
- Let the soft baked banana cookies cool on the baking sheet itself after taking them out of the oven so they have time firm up.

How runny should the batter be before refrigerating? My batter seems pretty runny.
Hi Alaina!
The batter should be fairy thick and hold together. Were you using Whey protein powder? I believe I used whey-caesin here. It’s more absorbent so sucks up a lot of moisture.
I’d say add some coconut flour to the batter if it’s still too runny to hold together when you take it out.
I tried these delicious cookies, I will definitely try other yummy recipes ??
It makes me so happy to know you loved them Claudia! Can’t wait to see what you try next!
