Preheat oven to 400ยบ F. Line a baking sheet with parchment paper and set aside.
Place the 2 sheets of puff pastry on a lightly floured surface and cut each sheet into 4 equal pieces.
In a small bowl, whisk together the Polaner All Fruit spread and cornstarch until smooth. Divide the mixture evenly onto the center of 4 puff pastry pieces, spreading it gently while leaving a 1/2-inch border around the edges.
In another small bowl whisk together the egg with 1 tablespoon of water. Lightly brush edges with the egg mixture.
Place the remaining puff pastry pieces over top and crimp the edges with a fork to seal.
Brush the tops lightly with the egg wash then bake until golden brown, about 20 minutes.
Let cool on a wire rack.
While they cool, make the icing by combining all ingredients in a small bowl and mix until well blended.
Once the pastries are cool, drizzle the prepared icing over top. Serve and enjoy!
