01 - Preheat oven to 375°F. Line a baking sheet with parchment paper or lightly grease a 24-cup mini muffin tin.
02 - Roll out pie dough on a lightly floured surface. Using a 2.5-inch round cutter, cut out 24 circles from the dough sheets.
03 - Gently press each dough circle into the cups of the mini muffin tin, forming small pastry shells. Alternatively, arrange on the prepared baking sheet.
04 - Spoon approximately 1 teaspoon of cherry pie filling into each dough cup, being careful not to overfill.
05 - Combine granulated sugar and ground cinnamon in a small bowl, mixing until well blended.
06 - Brush the edges of each pie bite with melted butter using a pastry brush, then sprinkle evenly with the cinnamon sugar mixture.
07 - Bake for 13 to 15 minutes until the crust is golden brown and the filling is bubbly. Watch closely to prevent over-browning.
08 - Let cool in the tin for 5 minutes before carefully removing. Serve warm or at room temperature.
