Roll out one pie crust onto a clean & dry countertop surface. Cut 12 rectangles from the pie crust, with each one being about 5" x 2". Place the 12 pieces onto the parchment paper on the baking sheet. * The easiest way to cut the rectangles is with a butter knife. Cut three rows and then four columns out of the pie crust. 1 package (15 oz) refrigerated pie crusts
Repeat the process with the second pie crust. Set the 12 rectangle shapes aside for now. * If you have extra dough, press it into a ball and roll it out again in order to get a total of 24 small rectangle pieces. In a mixing bowl, stir together the pure pumpkin, light brown sugar, and pumpkin pie spice.
1⅓ cups pure pumpkin, 2/3 cup packed light brown sugar, 2 teaspoons pumpkin pie spice
Place 2 tablespoons of the pumpkin mixture onto the center of each rectangle pie crust on the baking sheet. Spread it out to cover all but 1/2-inch around each edge.
Whisk together the egg and milk. Use a pastry brush to brush the outside edge of each pie crust around the pumpkin pie filling.
1 large egg, 1 tablespoon milk
Gently press a rectangle pie crust (that was set aside from earlier) on top of each pop tart with pumpkin pie filling on it. Crimp the edges with a fork.
Brush the remaining egg wash over top of each pop tart and gently poke a few holes in each one to allow excess air to vent. * Use a fork or toothpick to poke some holes. Bake for 8-12 minutes or until golden brown all over. Remove the pan from the oven and allow them to cool, on the warm baking sheet, while you prepare the glaze.
