Peel and core the apples. Cut each apple into 8 wedges.
Roll out the crescent roll dough on a lightly floured surface and separate it into triangles.
Place one apple wedge at the wide end of each triangle of dough and roll the dough around it, pinching the seams to seal. Place the finished dumplings in a greased baking dish.
In a mixing bowl, combine the sugar and ground cinnamon. Sprinkle this mixture evenly over the dumplings.
Pour the Mountain Dew over the dumplings in the baking dish, ensuring they are well coated.
Bake in the preheated oven for 30 minutes or until golden brown and bubbly.
Allow to cool slightly before serving. Enjoy warm on their own or with a scoop of vanilla ice cream.
Notes
Feel free to add nuts or raisins to the apple filling for extra flavor.Serve with caramel or whipped cream for an indulgent treat.
