5 c. chopped rhubarb
1 (3 oz.) pkg. raspberry or strawberry Jello
1 c. sugar
3 c. miniature marshmallows
1 pkg. yellow or white cake mix

Place rhubarb on bottom of a greased 9 x 13 inch baking dish. Sprinkle gelatin over rhubarb. Top with sugar, then marshmallows. Prepare cake mix according to package instructions. Pour batter over marshmallows and bake at 350 degrees for 1 hour or until cake tester inserted in center comes out clean. Turn cake out onto a piece of foil large enough to fold over cake. Turn edges of foil up to form a rim. Cool. Top with whipped cream or ice cream.
