Combine all ingredients into a food processor and pulse until evenly combined and a sticky batter is formed

Place batter on parchment paper in a rectangular pan and use hands to press batter together into a firm rectangle shape

Cover and place in the freezer for a minimum of four hours or ideally overnight

Then slice into bars or squares

Place parchment paper in between bars to keep them from sticking together

Store in the refrigerator in an airtight container
