Can I Use Any Kind of Oats?

How To Make the Chewy Banana Oatmeal Cookies

Step 1: Mash the Bananas

In a large mixing bowl, mash 2 large ripe bananas until smooth.

Step 2: Mix the Wet Ingredients

Add 1/2 cup brown sugar, 1/3 cup neutral oil, 1 egg, and 1 teaspoon vanilla extract to the mashed bananas. Whisk until everything is well combined.

Step 3: Combine the Dry Ingredients

In a separate bowl, whisk together 1 cup all-purpose flour, 1/2 teaspoon baking soda, 1/2 teaspoon cinnamon, and 1/4 teaspoon salt.

Step 4: Bring It All Together

Add the dry ingredients to the wet mixture and stir until just combined. Fold in 1 and 1/2 cups rolled oats. If using, mix in 1/2 cup chocolate chips or chopped walnuts.

Step 5: Scoop and Bake

Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper. Scoop the dough into 2-tablespoon mounds and place them 2 inches apart on the baking sheet. Bake for 11–13 minutes, or until edges are golden and centers are set.

Step 6: Cool and Enjoy

Let cookies cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.
