Soak the pitted medjool dates in warm water for 10 minutes and then pat them dry. Add oat flour to a blender and slightly pulse until a flour forms. Then, add in the dates, protein powder, nut butter, and sandwich cookies. Pulse until a dough forms. Roll the dough into balls and place them in the fridge while you melt the white chocolate. To melt the white chocolate, add 1 tsp of coconut oil. Dip the balls into the melted chocolate until fully coated, then top with extra crushed cookies. Place the balls in the fridge for at least an hour to set. Store any leftover balls in the fridge and enjoy!
