Preheat the oven to 425°
Line a baking sheet covered with parchment paper, set aside
Roll the pie crusts flat Cut 10-12 small squares (or make them bigger or smaller as desired) onto each pie crust for a total of 20
Place 10 of the square crusts on the lined sheet
Scoop one tablespoon of strawberry preserves onto one crust
Using a knife, smooth it out but do not spread it out all the way to the edge
gently dab the edges with a little water
Top the strawberry preserves with another piece of square crusts
Use a fork to crimp the edges of the crust and make sure no strawberry preserves leak out
Bake the pop-tarts in the oven at 425 for 12 minutes
Let the strawberry pop-tarts cool while you make the icing
Make the icing by combining 1 cup of powdered sugar with 1 tablespoon of milk, then add just enough milk to make it of thick drizzling consistency
Stir it until it is smooth, if it is too thick add a splash of milk and stir again
Drizzle or dollop the frosting onto the strawberry pop-tarts and spread smooth with a knife
Add rainbow sprinkles as desired and serve while still slightly warm
