How to Make 3-Ingredient Chocolate Oat Cookies

PIN IT

Step 1: Preheat

Preheat oven to 350°F (175°C).

Line a baking sheet with parchment paper.

Step 2: Mash Bananas

In a bowl, mash bananas until smooth and creamy.

The riper they are, the sweeter your cookies will be.

Step 3: Mix Ingredients

Stir in:

• Rolled oats
• Cocoa powder

Mix until fully combined.

The dough will be thick and slightly sticky.

Fold in optional chocolate chips if desired.

Step 4: Shape

Scoop spoonfuls onto baking sheet.

Flatten slightly with the back of a spoon — they won’t spread much.

Step 5: Bake

Bake 12–15 minutes.

Edges should look set but centers remain soft.

Let cool on pan 5 minutes before transferring.

They firm up as they cool.
