1 package yellow cake mix
4 cups rhubarb, diced
1 1/2 cups sugar
1 pint whipping cream

Prepare the cake mix as directed. Pour the mixture into a 9 x 13-inch greased pan. In a medium bowl, mix the rhubarb and sugar together. Evenly sprinkle the rhubarb mixture over the batter. Pour the whipping cream over the entire mixture. (It will look very runny.) Bake in a 350 degree oven for 40 to 45 minutes or until the cake tests done.
