Preheat oven 375°F. Spray a mini-muffin tin with non-stick spray or coat with Wilton Cake Release.
Dice apple small and place in a small bowl. To the bowl, add sugar, flour, butter, and cinnamon. Stir well to coat the apples.
Unroll your pie crusts. I used a 2-inch round cookie cutter to cut 40 circles of pie crust. Gently place them in the muffin tin and press to fit. It's much easier to get the pie crust into the little muffin tin if you use a tart tamper.
Spoon the apple mixture into the pie shells, filling to the top.
Bake at 375°F for 20 to 25 minutes or until the crust starts to brown.
Allow the mini pies to cool a few minutes before carefully removing them to cool on a wire rack. Serve with a dollop of whipped cream.
