Banana Oatmeal Cookies are a healthy cookie recipe made with just 3 ingredients! You can stir them together in just minutes, without using flour or refined sugar.
Preheat the oven to 350ºF and line a large baking sheet with parchment paper. Peel the bananas, then add them to a mixing bowl and mash them with a fork, until they are relatively smooth.
Add in the peanut butter, and stir well. Then, add in the oats and stir again. Add in any extras you like, such as mini chocolate chips, walnuts, or raisins. (You can add a pinch of cinnamon in that case, too!)
Use a 1-ounce cookie scoop or heaping tablespoon to drop the cookie dough onto the lined baking sheet. You should get 15 to 16 cookies from this batch. Flatten the dough with fork, so it's about a 1/2-inch thick, then bake at 350ºF for 10 to 12 minutes. The cookies will look lightly golden and dry around the edges when they are done.
Let the cookies cool on the pan for at least 15 minutes, then they are ready to serve. Leftovers can be stored in an airtight container in the fridge for up to 1 week, or you can freeze them for up to 3 months. You can even eat these cookies straight from the freezer for an easy treat.
