How to Make 3 Ingredient Banana Oat Cookies
Preheat your oven to 350°F (175°C). This ensures your cookies bake evenly and develop a nice, golden color.
Mash 3 ripe bananas in a large mixing bowl until completely smooth. The riper the bananas, the sweeter your cookies will be!
Stir in 1.5 cups of rolled oats. Mix until the oats are thoroughly coated and evenly combined with the banana mixture.
Incorporate 1/3 cup of chocolate chips (or your favorite add-ins). Gently fold them into the mixture, making sure they’re evenly distributed.
Shape the mixture by hand into flat discs. Aim for about 1 to 2 inches in diameter, and place them on a lined cookie sheet.
Bake in the preheated oven for 12 to 15 minutes. The cookies should look slightly soft when done, indicating they’re perfectly chewy inside.
Cool on the baking tray for a minute before carefully transferring them to a wire rack to cool completely.
