Preheat oven to 425°F. Peel, core, and chop apples into 1/4-inch pieces. In medium bowl, combine apples, sugar, flour, and cinnamon, tossing gently. Set aside.
Open and unroll pie crust using a flat surface. Take a 4-inch bowl or cup and cut five circles out, reserve the scraps. Press each circle inside 5 spaces in a muffin tin for Texas style muffins. Evenly divide the apple mixture in each prepared muffin. Top with reserved crust that has been cut into strips.
Bake until bubbling, about 18 minutes. Let pies cool completely before removing.
