1 (18 oz.) pkg. yellow cake mix
Prepare cake mix as the package directs. Pour into greased and bottom floured 9 x 13 inch cake pan. Spread the rhubarb evenly on top of the cake batter. Sprinkle the sugar over the rhubarb. Pour 2 cups whipping cream evenly over entire mixture. Bake at 350 degrees for about 45 minutes.Serve warm. You may add whipping cream on top, but I don't think that it needs it! Store in refrigerator, if there's any left to store. Enjoy!
