You will love these hearty peanut butter banana breakfast cookies. They come together in just 1 bowl with only 8 ingredients. These are an easy, wholesome, and quick breakfast or anytime treat!
Preheat the oven to 325°F. Line two large baking sheets with silicone baking mats or parchment paper. Set aside.
In a large bowl, whisk together the mashed banana, peanut butter, maple syrup, and vanilla until combined. Then, fold in the oats, cinnamon, salt, and walnuts. The dough will be thick and sticky.
Not required, but recommended, for easy handling of the dough, spray your hands with nonstick baking spray. Scoop mounds of dough, about ¼ cup each, onto the baking sheets. Place 6 cookies per baking sheet. The cookies don't spread much in the oven, so gently flatten the tops.
Bake for 18-20 minutes until lightly browned on the sides. These cookies took exactly 19 minutes. Allow the cookies to cool for 10 minutes on the baking sheet before transferring to a wire rack to cool completely.
Cookies can be eaten as is, broken up over yogurt or smoothie bowl. Cover and store cookies at room temperature for up to 4 days or in the refrigerator for up to 1 week.
