Get your oven ready by preheating it to 400°F. Let pie crusts rest at room temperature for about 15 minutes to make them easier to handle.

Peel off the apple skins, take out their cores, and slice them into pieces about 1/4-inch thick. Toss the slices with lemon juice in a bowl so they don’t brown.

Stir together flour, sugar, and cinnamon thoroughly. Coat the apple slices with this mix in even layers. Put the coated apples in a medium pot, add butter on top, cover, and gently cook over medium heat until the apples become soft.

Roll out the pie crusts on a floured surface. With a 3.25–3.5-inch biscuit cutter, cut out dough circles and press them gently into each cup of a standard muffin pan.

Scoop about 2 tablespoons of the apple filling into each dough cup. Use the leftover pie crust to either slice out thin strips for a crisscross pattern or cut smaller 2.5-inch circles to use as lids.

Whisk together water and the egg for a wash and brush this over the top of each mini pie. Sprinkle with sugar. Put the muffin tin on a parchment-covered baking sheet and bake for 15 minutes until they’re golden.
