Preheat your oven at 400 F.
Unroll the dough on a lightly floured surface. Use a knife or pastry cutter to cut out rectangles (about 3x5 inches). You’ll need two rectangles per Pop-Tart.
Place one rectangle on a baking sheet lined with parchment paper. Spread about 1 tablespoon of your chosen filling in the center, leaving a small border around the edges.
Beat the egg for your egg wash.
Use a pastry brush to brush the edges of the pastry with the egg wash. Then place another rectangle on top.
Press the edges together with your fingers, then use a fork to crimp the edges for a classic look. Poke a few holes on top with a fork to allow steam to escape.
Brush the tops of the Pop-Tarts with egg wash for a golden finish.
Bake for 12-15 minutes or until golden brown. Let them cool on a wire rack before adding glaze.
Mix the powdered sugar, milk, strawberry jam and vanilla extract until smooth.
Drizzle or spread the glaze over the cooled Pop-Tarts, then top with sprinkles if desired. Let the glaze set before serving.
