Dulce de Leche Apple Pie

⅓ cup white sugar

3 tablespoons cornstarch

1 ½ teaspoons ground cinnamon

1 ½ cups dulce de leche

5 large baking apples - peeled, cored, and sliced

1 (14.1 ounce) package pastry for 9-inch double-crust pie

Preheat oven to 450 degrees F (230 degrees C).

Mix sugar, cornstarch, and cinnamon together in a bowl until well blended. Add dulce de leche; stir until evenly distributed in the sugar mixture. Stir in apples until evenly coated.

Roll out pie crusts on a lightly floured work surface. Line a 9-inch pie plate with 1 crust. Pour in apple filling, heaping it in the middle. Cover with second crust. Pinch edges together to seal. Cut several slits into the top with a sharp knife.

Bake in the preheated oven until edges are golden, about 20 minutes. Reduce oven temperature to 350 degrees F (175 degrees C). Continue baking until apples are hot and bubbling, 25 to 30 minutes more.
