01 - Preheat oven to 375°F. Line a baking sheet with parchment paper.
02 - Unroll the pie dough and use a 2.5-inch round cutter to cut out 12 circles.
03 - Gently press each circle into the wells of a mini muffin tin, forming small cups.
04 - Spoon approximately 1 tablespoon of cherry pie filling into each cup.
05 - If desired, brush exposed pastry edges lightly with beaten egg for a golden finish.
06 - Mix granulated sugar and cinnamon together, then sprinkle over the tops of the bites.
07 - Bake for 13-15 minutes, or until the pastry is golden brown and the filling is bubbly.
08 - Let cool in the tin for 5 minutes, then carefully transfer to a wire rack to cool completely.
