Preheat the oven to 350 degrees and line a 9x9 inch baking dish with parchment paper.
Take 3/4 of the sugar cookie dough and press it down evenly in the bottom of the baking dish, bringing it up a little on the sides to form a crust.
Pour the cherry pie filling on top of the sugar cookie dough.
With the remaining dough, place dollops all over the cherry pie filling.
Bake at 350 for 50-60 minutes until the cookie dough on top is slightly golden.
Allow the bars to FULLY cool before transferring to the fridge for at least 1 hour before slicing and serving.
Create the glaze by mixing 1 cup powdered sugar and 1 tbsp milk. Whisk to combine and add a dash of milk to thin out the mixture if needed. Drizzle on top of the bars, slice, and enjoy!
