To a food processor add the soaked dates, nut butter, egg and vanilla, pulse until a paste forms. Remove blade from food processor and add the dry ingredients in, mix with a spoon. Place in fridge for about 5 minutes for dough to set. Scoop dough into balls and place onto a parchment-lined baking sheet (dough will be sticky so use an ice cream scoop or spoon). Slightly press dough with hands and top with extra chocolate chips. Bake at 350°F for 9–11 minutes, or until the edges are set. Let cool slightly before enjoying, they firm up as they cool!
