Preheat oven to 350 degrees F. Grease 9x13-inch baking dish.
Peel and core apples. Cut each apple into 8-10 slices.
Unroll crescent dough. Cut each triangle into two smaller triangles. You will end up with 32 dough triangles from the two packages.
Place an apple slice on the short side of each triangle and roll up to the point, wrapping dough around each apple slice.
Arrange crescent-wrapped apples in greased pan.
In a medium bowl, stir together melted butter, brown sugar, and cinnamon. Pour the mixture over apple dumplings.
Pour the Sprite in the center and along the edges of the pan. (Do not pour directly on the dumplings.)
Bake uncovered 33-36 minutes until golden brown.
