Preheat your oven: Start by preheating your oven to 350°F (175°C). This ensures that your dumplings bake evenly.
Prepare the apple: Peel and core 1 large apple, then cut it into 8 wedges. This size allows for easy wrapping and ensures the apple cooks thoroughly.
Wrap the apple: Take a wedge of apple and wrap it in a piece of the Pillsbury Crescent dough, pinching the seams to seal. Repeat this for all apple wedges.
Make the buttery sauce: In a saucepan, melt ½ cup of butter over medium heat. Once melted, stir in ¾ cup of sugar and 1 tsp of cinnamon. Mix until well combined, and then drizzle this mixture over the wrapped dumplings.
Add the soda: Carefully pour 1 cup of Mountain Dew around the dumplings in the baking dish. This soda will help create a wonderful sweet syrup that complements the dumplings.
Bake the dumplings: Place the dish in the preheated oven and bake for 30-35 minutes or until the dumplings are golden brown. Keep an eye on them to gauge doneness; they should be beautifully puffed.
Serve warm: Once done, remove the dumplings from the oven and let them cool slightly. Serve warm, topped with the buttery sauce for an irresistible dessert. Enjoy!
