Apple Pie Crescents

I don't know what these are really called so I made the name up. Call them what you want, but go make some now! I usually don't like baked apple things, but I absolutely love these (must be the cube of butter :). And they're easy!

1 apple, peeled and sliced into 8 pieces (I used Fuji)
1 can refrigerated Pillsbury crescent rolls
1 cube butter
2/3 c. sugar
1/2 tsp. cinnamon
1/2 tsp. vanilla
1/2 can Sprite

Roll 1 apple slice into one triangle crescent roll. Pinch sides together and place in a greased baking pan. In saucepan melt 1 cube butter, then add sugar and cinnamon. When it comes to a boil, remove from heat and add vanilla. Pour over rolls, then pour Sprite on rolls. Bake at 350 for 40 minutes. Serve hot with vanilla ice cream!
