Preheat your oven to 350 degrees and line a baking sheet with non-stick foil or parchment paper.
Mash 2 ripe bananas in a bowl, and then mix in up to 2 tbsp of unsweetened cacao powder and 1 cup of quick oats until a cookie dough-like batter is formed (the amount of oats you need depends on the size of your bananas, so start with 3/4 of a cup and add more as needed). The mixture will seem dry at first, but after a few minutes of mixing with a spoon, it will turn into a nice consistency.
Fold in any mix-ins you plan on adding to the batter (I added a large handful of chocolate chips).
Place about 15 clumps of your cookie dough mixture evenly on your baking sheet. Flatten and mold them with your hands to form “cookie” shapes (these cookies will not flatten or change shape with baking).
Bake at 350 degrees for 10-15 minutes.
Enjoy!!
