How to Make It
Preheat the oven to 350°F. Mist a 9-inch pie plate with cooking spray.
Peel and core the apple, and cut into 8 equal wedges.
Separate the dough into rectangles. Place an apple wedge on the wide edge of a dough triangle, roll up, and place in the pie plate. Repeat with the remaining wedges and dough.
Whisk together the melted butter, brown sugar, spice, and vanilla. Pour over the dumplings.
Pour the soft drink around the edges of the rolls, but not over them.
Bake until deep golden brown, about 30 minutes. Let stand at least 10 minutes before serving warm.
