Preheat the oven to 350°F (175°C).

In a large bowl, cream together the softened butter, cream cheese, and sugar until smooth.

Add the corn syrup and the egg, mixing until well combined.

In another bowl, whisk together the flour, baking soda, and salt.

Gradually add the dry ingredients to the butter mixture, mixing until just combined.

Fold in the Pop Tarts, reserving a few pieces for topping.

Drop tablespoons of dough onto a baking sheet lined with parchment paper.

Bake in the preheated oven for 10 minutes or until lightly golden.

If using icing, mix powdered sugar, water, and food coloring together to desired consistency and drizzle over cooled cookies. Add sprinkles if desired.
