  • Remove from oven, and let cool on a wire rack.
  • To serve, either dust the top with powdered sugar, or slice and invert the cake so that it's "upside down" with the fruit on the top of the cake.

Notes

    • Use the yellow cake mix of your choice. Our ingredients above are based on a Betty Crocker Super Moist Cake Mix. 
    • When making cake batter, use the instructions on your cake mix box.
    • For a fruitier rhubarb cake, use 6 cups of diced rhubarb.
    • Fresh rhubarb works best. Frozen rhubarb releases a lot of water changing the consistency.
    • I typically use a regular Jello mix. The sugar-free Jello mix should theoretically work; however, I have not tested this version.
    • Serve one of two ways. Serve with the fruit on the bottom of the cake or invert and serve as an upside down cake with the fruit on the top.
