1 (18 oz.) pkg. white or yellow cake mix
3 c. rhubarb, diced
1 c. sugar
2 c. whipping cream
Whipped cream for topping

Prepare cake mix as package directs. Pour into greased and bottom floured 9 x 13 inch cake pan. Arrange rhubarb evenly on top of batter. Sprinkle on sugar. Pour 2 cups whipping cream evenly over entire mixture. Bake at 350 degrees for 40 to 45 minutes. Serve dessert warm with whipped cream on top. Store in refrigerator. (A delicious custard forms at the bottom of the pan as cake bakes.)
