Preheat the air fryer to 375 degrees F for 5 minutes. This ensures an even cooking temperature from the start.
Unroll the pie crusts onto a lightly floured surface and cut out as many 2×3 inch rectangles as you can—aim for about 6 per crust. This gives you the perfect shape for your pop tarts.
Gather any dough scraps and re-roll them to an ⅛ inch thickness. You can create additional rectangles by repeating this process, yielding about 4 more.
Take 2 teaspoons of jam and place it in the center of one rectangle. Then, lay another rectangle on top, sealing it within.
Pinch the edges to secure the filling, ensuring that none leaks out during cooking.
Using a fork, poke the top of the pop tart to create vents, which allows steam to escape as they cook. Then crimp the edges with the fork to ensure they are sealed well.
Repeat the process with the remaining rectangles until all pop tarts are prepared.
Beat the egg with a splash of water to create an egg wash. Brush this over the top of each pop tart for that lovely golden finish.
Carefully place a few pop tarts into the preheated air fryer, making sure not to overcrowd the basket. You may need to cook in batches.
Cook at 375 degrees F for 8 to 10 minutes or until the pop tarts are golden brown and crisp. Keep an eye on them to avoid burning.
Once cooked, transfer the pop tarts to a wire rack and let them cool completely before frosting.
In a small bowl, whisk together the powdered sugar, 1 tablespoon of milk, vanilla extract, and food coloring. Adjust with more milk if the frosting is too thick.
Spread the frosting over the cooled pop tarts and top with sprinkles for a festive finish.
Allow the frosting to set for about 10 minutes before serving, ensuring a delightful crunch.
