Preheat the oven to 425 degrees and line a baking sheet with parchment paper.
Roll out each pie crust dough into a rectangle roughly 17x13 inches in size. Cut 8 rectangles out of the dough, each measuring 4"x6" inches. Repeat with the second pie crust.
1 package 9" refrigerator pie crust
When all 16 pieces of 4x6 inch dough are cut, poke holes in the center of 8 using a fork. These will be the tops of your pop tarts.
In a small saucepan, heat the jam over medium heat. While the jam is heating up, dissolve the cornstarch and water in a small mixing bowl.
1/2 cup strawberry jam, 1 TBS cornstarch, 1 TBS cold water
Add cornstarch mixture to the jam and stir continuously until mixture begins to boil. Once boiling, remove from heat and set aside.
Place the bottoms of your pop tarts (the 8 pieces without holes) on your baking sheet. Carefully spoon out ½ tablespoons at a time of your jam mixture. Once all bottoms are covered with the jam mixture, place the tops of your pop tarts (the 8 pieces with holes) and place directly on top of each slice.
Use the ends of a fork to press along the edges of the pop tarts, combining together the dough from the tops and bottoms.
Place the sheet of pop tarts in the oven and cook for 8 minutes.
While your pop tarts are cooking, begin mixing your icing. In a small mixing bowl, combine the powdered sugar, milk and vanilla. Mix until smooth.
When cooking time is complete for the pop tarts, remove from the oven and immediately pour your icing over pop tarts and top with sprinkles if desired.

Allow pop tarts to cool before eating.
Notes
Store any leftover pop tarts in an airtight container at room temperature for up to five days. You can eat them right from room temperature or if you’d like, you can warm them up in the oven for a few minutes to enjoy them warm all over again!If you’d like to freeze the pop tarts, wrap each one individually in plastic wrap then place all of them in a freezer safe gallon size bag. Freeze for up to three months, taking them out individually to let them thaw on the counter overnight when you’re ready to eat!Try different variations with different jams or combination of jams like blueberry, blackberry, and raspberry! If you want a thicker crust start with cutting 6 rectangles out of a 12×12-inch rectangle. then re-roll the excess dough to make the final two pieces.Try making shapes for different holidays! These are really fun as Christmas trees, hearts, and even Easter eggs!Make an egg wash to give the pop tarts a glossy golden brown color by beating one egg with one tablespoon of water then brushing the pop tarts all over with the mixture before baking. This is an extra step, but it does give them a fun touch of color!Spoon the jam mixture onto the pop tarts while the jam is still warm to ensure that it spreads to the entire pop tart. No need to spread it around to the edges on your own, it will melt and spread when cooking.
