Make a batch of homemade pop tarts from scratch with a flaky pastry filled with cinnamon brown sugar, baked until golden then topped with a cinnamon vanilla glaze.
Cut in cold butter with flour. In a large mixing bowl, whisk together 2 1/2 cups flour and 1 teaspoon salt. Add 1 cup cold, cubed butter and use a pastry cutter to mix the butter into the flour until the mixture resembles coarse crumbs.
Make pastry dough. Adding 1 Tablespoon water at a time, stir until the dough comes together to form a ball. Stop adding water when this happens or you will end up with sticky dough.
Chill. Turn out the dough onto a floured surface and shape into a flat disk (I like to divide in 2 to make it easier to roll out). Wrap in plastic wrap and chill in the refrigerator for at least 30 minutes.
Make the Filling
Combine brown sugar filling. In a small bowl, mix together 1/2 cup brown sugar, 2 teaspoons cinnamon, and 1 Tablespoon flour until well combined. Mix the butter in with a fork until combined. Set aside.
Assemble the Pop Tarts
Line baking sheet. Line 2 baking sheets with parchment paper. Set aside
Roll out pastry. On a floured surface, roll out the pie crust into a rectangle about 1/8-inch thick. Cut into rectangles (about 3x4 inches each). Place 9 on a baking sheet.
Add filling. Place the filling in the center of half of the rectangles, leaving a small border around the edges.
Seal with egg wash. Brush the edges of the filled rectangles with the egg wash, then place another rectangle on top. Use a fork to crimp the edges together.
Chill unbaked pop tarts. Prick the top of each with a fork to allow steam to escape. Refrigerate for 20-30 minutes (we want the butter in the dough to go in the oven cold, so they don't spread).
Bake
Preheat oven. Preheat oven to 375°F.
Bake. Brush tops with remaining egg wash. Bake in the preheated oven for about 25-30 minutes, or until golden brown. Let cool on the baking sheet for a few minutes, then transfer to a wire rack.
Frost the Pop Tarts
Cool then glaze. In a medium bowl, whisk together powdered sugar, milk, and vanilla extract until smooth. Spread the frosting over the cooled pop tarts and allow to set.
Notes
Note: This recipe makes 9 large poptarts. One poptart serves 2 people (I like to cut them in half to serve). Storage: These homemade pop tarts are best enjoyed the day they are made, but you can store them in a covered container at room temperature for up to 3 days.
