Step 1

Set the oven rack to the upper-middle position. Then preheat the oven to 350°F (177°C).

Step 2

Line a baking sheet with parchment paper or a nonstick baking mat and set aside.

Step 3

Peel the bananas and place on a large plate. Using a fork, mash them until smooth with no more lumps.

Step 4

Add the oats and mashed bananas to a medium-size bowl and mix well. If the mixture seems too wet, mix in a few more tablespoons of oats.

Step 5

Add the chocolate chips and stir to combine.

Step 6

Scoop one tablespoon of batter onto the baking sheet and flatten it to about ½-inch (12 mm) thick with your fingertips. Repeat for the rest of the batter, spacing the cookies an inch apart.

Step 7

Bake for 15 – 20 minutes until puffy.

Step 8

Remove from oven. Let the cookies cool for 5-10 minutes and then use a rigid spatula to remove to a wire rack to cool completely.
