Bring dough to room temperature. Preheat oven to 375°F.
Line a sheet pan with parchment paper and spray lightly with cooking spray. Dust the countertop with gluten-free flour. Roll out puff pastry dough to approximately 1/4-inch thick. You can use a roller with a design on it if you like.
Cut out cookies as desired. Carefully place them on the sheet pan.
Dock cookies so they don’t rise. You can use the tines of a fork. Brush with egg wash. Sprinkle colored sugar at this time if using.
Bake for 20 to 30 minutes or until golden brown. Let cool completely.
