Preheat oven to 400°F and line 2 baking sheets with parchment paper or prepare a pizza stone according to stone's directions.
Toss the apple slices with the cornstarch until slices are all covered. Add Sea Salt Caramel Sauce and gently toss until coated.
Mix together the ricotta cheese with 1 teaspoon of ground cinnamon.
Divide the pizza dough into 4 sections. Roll out one section on a floured surface to be about ¼” thick circle. Line half of the circle with ¼ cup of the ricotta and top with ¼ of the apple caramel mixture, leaving the outer 1” empty.
Fold the empty dough over the apples and to create a half circle and pinch the edges together well with floured fingers. Roll the edges inward to create a good seal.
In a small bowl, mix together the remaining cinnamon with the granulated sugar.
Place the calzones onto the prepared pans. With a sharp knife, make 2-3 slits along the top to allow air out. Brush the tops with melted butter and sprinkle with cinnamon sugar mixture. Bake for 15-20 minutes, until calzones have browned.
Serve warm with additional Sea Salt Caramel Sauce for dipping.
