I think I rolled the dough too thin, otherwise these were a great alternative to the boxed who-knows-what's-in-them kind. If you use the store-bought crust, I wouldn't roll it out much more than it already is. Also, I would recommend letting them cool a lot before drizzling the icing over them or it just melts right off.
If anyone tries this recipe with any variations let me know. I think it's a decent recipe but there is a lot of room for improvement.
Homemade Pop Tarts
pie crust - home made or store bought
jam or preserves
Preheat oven to 425. Roll out pie crust and cut into rectangles. Be sure they are all the same size. I used a pizza cutter to cut the dough and it worked great. Gather up scraps and re-roll until all dough is used.
Put about a tbsp of jam on half of the rectangles. Top with another crust and crimp edges - I used a fork to do this. Place on baking sheet and bake for 7-9 minutes. Watch them because they go from done to oozing quickly.
Mix together 1 cup powdered sugar with just a little bit of milk until a thick syrup forms. The thicker it is, the better it will hang on to the pastries.
Allow pastries to cool before drizzling with icing.
