Line a baking sheet with parchment paper and set aside.

Mix the jam and cornstarch together in a small bowl and set aside.

Whisk the egg in a small bowl and set aside.

Preheat oven to 400F.

Lay out the pie dough onto a floured work surface. Using a knife or pizza cutter cut off about an inch on the sides, top and bottom to create a 9" square. Cut three 3" strips out of each square.

Place one to two tablespoons of the jam mixture on each strip and spread out on half the dough but not completely to the sides. Brush the egg around the edge of the rectangle. Fold the dry end over the jam end.

Using a fork seal the edges. Place the Pop Tarts on the baking sheet and bake for 15-18 min. until golden.

Remove from oven and let cool.

Whisk the powdered sugar with the cream until you get the right consistency. Drizzle or spread onto the Pop Tart. Immediately add the sprinkles and leave to dry. Serve at room temperature.
