Preheat the oven to 350 degrees and line a baking sheet with parchment paper.
Rinse and drain chickpeas, remove chickpea skins.
Put all ingredients except chocolate chips in a food processor or high power blender and blend until a smooth dough forms. You can also mix this by hand, combining wet ingredients first (peanut butter, vanilla, and maple syrup) and then adding in the dry ingredients (sugar, baking powder, oat flour). Stir well.
One you have your dough, fold in chocolate chips with a spatula.
Roll 1/4 cup dough balls and line a baking sheet (you can also make smaller cookies if you prefer). This batter makes a lot of cookies, so you might need to do two rounds of baking.
