Something went wrong. Our team is working on it. Original recipe (1X) yields 12 servings 1 (15.25 ounce) package moist yellow cake mix 1 cup water 3 large large eggs 1/3 cup vegetable oil 2 cups diced rhubarb 1 ¼ cups white sugar 1 cup whipping cream Directions Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 9x13-inch baking pan. Prepare cake batter by combining cake mix, water, eggs, and oil together in a large bowl; beat with an electric mixer on low speed until moistened. Increase speed to medium and beat for 2 minutes. Pour batter into prepared baking pan. Combine rhubarb and sugar together in a bowl; spoon over batter in the pan. Drizzle whipping cream over the top. Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 40 minutes. Let cake cool completely before turning it out onto a serving dish. Editor's Note: The directions for making the cake batter are based on a Duncan Hines Classic Yellow Cake Mix. Follow the instructions on the box regarding oven temperature, added ingredients, and cooking time if using a different brand. I Made It Print 100 home cooks made it!
