Instructions: Grease a 13x9-inch baking dish. Heat oven to 350 degrees.

Prepare cake batter as directed on package. Spread in prepared pan. Top with rhubarb and lemon peel; sprinkle with sugar.

Bake 40-45 minutes. As the dessert bakes, rhubarb goes to the bottom, forming a sauce and the cake rises to the top.

If desired, sprinkle top of cake with powdered sugar right after baking.

Serve warm with cream.

Makes 12 servings.
