How to Make 3-Ingredient Peanut Butter Oatmeal Cookies
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Step 2: Mix the Dough
In a bowl, mash the banana until smooth. Stir in peanut butter until fully combined, then fold in oats. The dough will be thick and sticky.
Step 3: Scoop and Shape
Scoop tablespoon-sized portions onto the baking sheet. Flatten gently with a fork—they won’t spread much.
Step 4: Bake
Bake for 8–10 minutes, until cookies are set and lightly golden on the edges.
Step 5: Cool
Let cookies cool for 5 minutes. They firm up slightly but stay soft inside.
