In a mixing bowl, add your oats and protein powder and mix well, until combined. In a microwave safe bowl, add your peanut butter and maple syrup. Microwave until the peanut butter has melted. Add the peanut butter mixture into the dry ingredients and mix until combined.
Using your hands, form small balls using the batter and place them on a lined plate. Refrigerate for at least an hour, to firm up.
