In a large skillet, melt butter over medium heat. Add the apples, brown sugar, and cinnamon, and stir until well combined. Cook, stirring occasionally, for about 10-15 minutes, until the apples are tender and the brown sugar creates a thick glaze (towards the end of cooking, you’ll need to stir more frequently as the glaze gets thicker).
for the Tacos
Preheat oven to 375°F and cut Flatout Foldits in half. Combine cinnamon and sugar in a small bowl. Brush one side of each Foldit with butter and sprinkle generously with cinnamon sugar. Using tongs, fold each into a taco shell shape and hang/drape over your oven rack grates. Bake for 7-10 minutes, until the Foldits turn golden brown. Remove from oven and let cool slightly. They will continue to crisp up as they cool.
Fill each taco shell with cooked apple mixture, and top with whipped cream and caramel sauce. Devour immediately.
