- 1 egg, beaten
- 2 tablespoons water
- 4 sheets frozen puff pastry
- Beat egg and water together in a small bowl.
- Cut two rounds from each sheet of puff pastry using a 3-inch round cutter, forming 8 circles. Use a 2 1/2-inch round cutter to cut through 4 of the rounds. Place entire cut round on top of an un-cut round. Brush each with egg mixture.
