Apple Dumplings

This is a recipe I got from another website-- it is SO incredibly good- but SO extremely fattening! Therefore, we don't have it very often :) There's not a person I know who has had them and not liked them!

2 Granny Smith apples
2 cans crescent rolls
2 sticks butter
1 1/2 cups sugar
1 teaspoon vanilla
cinnamon
1 can Mountain Dew

Peel and core apples. Cut apples into 8 slices each. Roll each apple slice in a crescent roll. Place in a 9 x 13 buttered pan. Melt butter, then add sugar and barely stir. Add vanilla, stir, and pour over apples. Pour Mountain Dew around the edges of the pan. Sprinkle with cinnamon and bake at 350 degrees for 40 minutes. Serve with vanilla ice cream or Cool Whip, and spoon some of the sauce from the pan over the top.
