Preheat oven to 450 degrees F. Line a baking sheet with parchment paper and set aside.
Add pie filling to a blender and puree.
On a cutting board roll out pie crust and cut out pop tart pieces with a 2 inch heart cookie cutter.
Lay bottoms of pop tarts on the prepared baking sheet.
Spoon 1-2 TBS of pie filling on each heart piece.
Place another heart piece on top and using a fork press the sides together.
Whisk one egg yolk with a teaspoon of water and brush the tops of each pop tart.
Sprinkle the brushed pop tart with sugar.
Using a sharp knife cut two slits in the middle to resemble a heart.
Bake for 5 minutes or until golden brown.
