01 - Preheat the oven to 375°F. Line a baking sheet with parchment paper or lightly grease a mini muffin tin.
02 - Roll out the pie dough on a lightly floured surface. Using a 2.5-inch round cutter, cut out 24 circles.
03 - Gently press each dough circle into the cups of a mini muffin tin or arrange them on the baking sheet, shaping small cups.
04 - Spoon about 1 teaspoon of cherry pie filling into each cup.
05 - Mix the granulated sugar and cinnamon in a small bowl.
06 - Brush the edges of each pie bite with melted butter, then sprinkle with cinnamon sugar mixture.
07 - Bake for 13-15 minutes, or until the crust is golden brown and the filling is bubbling.
08 - Allow to cool for 5 minutes before removing from the tin. Serve warm or at room temperature.
