Pre-heat oven to 350F degrees. Spray 12 muffin cups with non-stick cooking spray.
Roll out a single pie crust on a flat surface. Using a round cookie cutter or small bowl, cut out circles of pie dough. Press dough circle into the bottom of a muffin tin. Repeat with remaining dough to fill all 12 muffin tins.
Fill each pie with about 1 Tablespoon of cherry pie filling. Bake for 25-30 minutes, or until the crust is lightly golden.
Remove and let cool for at least 15 minutes. Then very carefully use a knife to loosen the edges of each pie and gently lift each pie out. Top with whipped topping and enjoy!
