    After making my Chocolate Oatmeal Cookies, I knew I had to make a banana version soon. This recipe is such a great way to use up ripening bananas!

    These cookies are exploding in flavours and textures! They have hearty oats that adds the perfect chew to them. Paired with the sweet chocolate and bananas and it's a combination that's out of this world delicious!

    They come together in one bowl with easy pantry ingredients. Let's get to baking!

    Step by step instructions

    Here is how to make and bake these chocolate banana oatmeal cookies. You will need two trays lined with parchment paper, two mixing bowls, a spatula, a whisk, and a standard 2 tbsp ice cream scoop.

    Step 1 - Prep. Preheat the oven to 350°F. Melt the butter and allow it to cool as you prep the rest of your ingredients. 

    Step 2 - Mix dry ingredients. Add the dry ingredients into a bowl; flour, sifted cocoa, oats, baking soda, baking powder, cornstarch, cinnamon, and salt. Stir to combine and set aside.

    Step 3 - Whisk butter and sugars. In a large bowl, add in the melted and slightly cooled butter, white sugar, and brown sugar. Whisk together for 1-2 minutes until combined.

    Step 4 - Mix in wet ingredients. Add in the eggs, vanilla, and mashed bananas. and Continue whisking for another 1-2 minutes until combined. It may be chunky from the bananas, that is normal!

    Step 5 - Add in dry ingredients. Mix the dry ingredients in gently with a spatula, just until a soft cookie dough forms. Do not over-mix!

    Step 6 - Mix in chocolate chips. Add the chocolate chips in and mix a few times until just combined.

    Step 7 - Scoop and bake. Scoop the cookies 6 at a time per tray, spacing them apart from one another. Add extra chocolate chips on top (optional).

    Step 8 - Bake. Bake the cookies for 13-16 minutes. They are ready when the edges are dry, and the middles are slightly puffy and not fully baked. They will continue to bake from the heat of the pan.

    FAQ

    How do I store these cookies?

    These cookies stay good on your counter in an airtight container for 3 days, and in the fridge for up to 1 week.

    Do I have to add bananas?

    Yes, it is a main ingredient in this recipe. If you want to make these without bananas, check out Chocolate Oatmeal Cookies.

    How do I know when these cookies are done?

    Since these cookies contain cocoa, they won’t have the typical golden-brown edges like regular cookies. Instead, they’re done when the edges look dry and slightly crisp, while the centres will remain soft and a bit underbaked. As they cool on the pan, the heat from the pan will continue to bake them to perfection!
