How to Make 3-Ingredient Peanut Butter Banana Cookies

1. Preheat the Oven

Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.

2. Mash the Bananas

In a mixing bowl, mash ripe bananas until smooth with minimal lumps.

The riper the bananas, the sweeter your cookies will be.

3. Mix the Dough

Stir in peanut butter and honey (if using) until fully combined. The mixture will be soft and slightly sticky.

4. Scoop and Shape

Drop spoonfuls onto prepared baking sheet. Flatten slightly with the back of a fork to create a crisscross pattern.

5. Bake

Bake for 10–12 minutes, until edges are lightly golden.

Let cool on the baking sheet for 5 minutes before transferring to a wire rack.

They firm up as they cool.
