They truly feel like a brownie disguised as a breakfast cookie.

Ingredients

2 ripe bananas (the riper, the sweeter)
1 cup rolled oats
3 tablespoons unsweetened cocoa powder

Optional Add-Ins (Highly Recommended!):

2 tablespoons dark chocolate chips
1 tablespoon peanut butter
½ teaspoon vanilla extract
Pinch of sea salt

Tools You’ll Need

Mixing bowl
Fork (for mashing bananas)
Baking sheet
Parchment paper

Substitutions & Additions

Blend oats first for a smoother cookie.

How to Make 3-Ingredient Banana Oat Cocoa Cookies

Step 1: Preheat

Preheat oven to 350°F. Line a baking sheet with parchment paper.

Step 2: Mash Bananas

In a bowl, mash bananas until smooth and mostly lump-free.

The smoother the mash, the better the texture.

Step 3: Add Oats & Cocoa

Stir in rolled oats and cocoa powder.

Mix until fully combined. The dough will be thick and sticky.

If adding chocolate chips or nut butter, fold them in now.

Step 4: Shape

Scoop spoonfuls onto baking sheet.

Flatten slightly — they won’t spread much on their own.

Step 5: Bake

Bake for 10–12 minutes.

The edges should look set, but the centers will stay soft.

Let cool for 5 minutes before moving.

That’s when they firm up into that perfect brownie-cookie texture.
