1-First Step: Prepare the Dough Start by combining 2 cups of flour and a pinch of salt in a large mixing bowl. Cut 1/2 cup of cold butter into small cubes and add it to the flour. Using a pastry blender or your fingers, work the butter into the flour until the mixture resembles coarse crumbs. You want to see small pea-sized chunks of butter remaining, as these create the flaky layers. Slowly drizzle in 1/2 cup of cold water, mixing gently until the dough just comes together. Form the dough into a disc, wrap it in plastic wrap, and refrigerate it for at least 30 minutes. Chilling the dough relaxes the gluten and solidifies the fat, which is essential for a tender crust.

2-Second Step: Make the Filling While the dough chills, prepare the signature brown sugar cinnamon filling. In a medium bowl, combine 1/2 cup of brown sugar, 1 tablespoon of cinnamon, and 2 tablespoons of flour. The flour here acts as a thickener to keep the filling inside the pastry rather than bubbling out. Add 1/4 cup of softened butter to the mixture and mash it with a fork until you have a smooth, spreadable paste. Set this mixture aside. If it feels too runny, pop it in the fridge for a few minutes to firm up slightly, which will make it easier to spread on the dough later.

3-Third Step: Roll and Cut Preheat your oven to 400°F and line a baking sheet with parchment paper. Remove the chilled dough from the fridge and cut it in half. On a lightly floured surface, roll out one half of the dough until it is about 1/8 inch thick. Using a knife or a pastry wheel, trim the edges to make a neat rectangle, then cut the dough into smaller rectangles. Aim for dimensions roughly 3 inches by 5 inches, or whatever size you prefer for your finished tarts. Repeat this process with the second half of the dough. Remember to keep an even count of top and bottom rectangles since you will be sandwiching them together.

4-Fourth Step: Assemble the Tarts Place half of the rectangles onto your prepared baking sheet. These will be the bottoms of your pop tarts. Spoon about a tablespoon of the brown sugar filling onto the center of each rectangle, spreading it out evenly but leaving a border of about half an inch around the edges. This border is crucial for getting a good seal. Place the matching top rectangles over the filling. To seal the edges, dip your finger in a little water and run it around the border of the bottom piece, then press the top piece down firmly. Use the tines of a fork to crimp the edges all the way around. This not only seals the tart but also gives it that classic ridged look. Poke a few holes in the top of each tart to allow steam to escape during baking.

5-Final Step: Bake and Glaze Bake the assembled pastries in the preheated oven for 15 to 18 minutes, or until they are golden brown and the edges are slightly crisp. While they are cooling, prepare the glaze by whisking together 1 cup of powdered sugar, 1 tablespoon of milk, and 1 teaspoon of vanilla extract. You want the glaze thick enough to stay on the tart but thin enough to pour. Once the tarts are cool enough to touch but still slightly warm, drizzle the glaze over the top. If you like sprinkles, add them now while the glaze is wet so they stick. Allow the glaze to set completely before serving. This method yields a soft, fresher taste without preservatives.
