Yes! You can freeze the pop tarts either before or after baking. If you want that freshly baked flavor, freeze the pop tarts on a cookie sheet before baking, then store them in an airtight container. Bake from frozen in a fully preheated oven. You may need an extra minute or two to compensate for the cold jam. If you know you want to freeze the pop tarts to bake later, leave the glaze off and decorate with a fresh batch right before serving. Baked pop tarts can also be frozen and stored for later. Since they've already been baked, they just need to be reheated.
