Apple Dumplings

These are sinfully delicious, we have had them a couple times at bookclub and each time everyone can't stop raving or eating!

2 Granny Smith apples
2 cans crescent rolls
2 sticks butter
1 1/2 cups sugar
1 teaspoons vanilla
cinnamon
1 small can Mountain Dew (about 2/3 cup)
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 ice cream, and spoon some of the
sweet sauces from the pan over the top.
