Grease 9x13" pan. Preheat oven to 350 dg.F. Peel, core, and cut each apple into 8 equal pieces. Open rolls and seperate. Wrap a piece of dough around each apple slice. Place face down in pan. In medium saucepan, melt butter, add sugar and stir until well mixed. Remove from heat; add vanilla. Pour butter mixture over rolls. Pour Mountain Dew around edge of pan and sprinkle rolls with cinnamon.
Bake @ 350 dg. F. for 40 minutes, uncovered.
Delicious alone, but even better with a scoop of vanilla ice cream!
