Preheat the oven to 400?F.

Add the pie crust mix to a large bowl, and then add in the water 1 tablespoon at a time while mixing with a fork until it forms dough. Form the dough into 2 balls.

Roll out the dough balls one at a time on a well-floured surface to a circle about 10 inches in diameter.

Use a heart-shaped cookie cutter (about 4 inches across) to stamp out as many hearts as you can. Repeat this process with the second ball of dough and gather all the scraps to roll out and stamp out more hearts.

Arrange 7 hearts on a large baking tray lined with parchment paper. Put about 1/2 tablespoon of jam on each heart and slightly spread it out, leaving a border of at least 1/4-inch all the way around.

Lightly brush the outside of each jam-topped heart with water. Place another heart-shaped piece of dough on top of each. Use the tines of a fork to lightly crimp the edges and seal the jam inside.

Bake until set, about 10 to 12 minutes.

Whisk together all ingredients for the glaze.

Transfer the pop tarts while they?re still warm to a wire rack placed on a baking tray. Spoon the glaze onto each, letting the excess drip off. Top with sprinkles immediately before the glaze sets.
