Preheat your oven to 350°F (175°C). Gather all your ingredients.

Mash 2 ripe bananas until smooth, then mix with 1/2 cup almond butter, 1/4 cup maple syrup, and 1 teaspoon vanilla extract.

In another bowl, mix 1.5 cups rolled oats, 1/2 cup chocolate chips, and 1/2 cup chopped walnuts.

Combine the wet ingredients with the dry ingredients until a cohesive dough forms.

Drop the dough onto a lined baking sheet, leaving about 2 inches between each cookie, and flatten slightly.

Bake in the oven for 12-15 minutes until edges are golden, and centers look soft.

Cool on the baking sheet for about 5 minutes before transferring to a wire rack.
