Step-by-Step Instructions for Banana Oatmeal Cookies
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a mixing bowl, use a fork to mash the bananas until they’re smooth with a few small lumps remaining.


Stir in the rolled oats until the mixture is well combined and forms a sticky dough.


Gently fold in the dark chocolate chips or raisins for added flavor.


Use a tablespoon or cookie scoop to drop portions of the dough onto the prepared baking sheet. Flatten each cookie slightly with the back of the spoon.
Bake the cookies for 12–15 minutes, or until they’re lightly golden around the edges.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Tips for Perfect Banana Oatmeal Cookies Every Time
