Ingredients

  • 5 cups sliced rhubarb (*see note)
  • 2 (3 oz.) packages strawberry gelatin (i used sugar free strawberry gelatin)
  • 1/2 cup sugar, or 12 packets of saccharin sweetener
  • 2 cups miniature marshmallows
  • 1 box (15.25 oz.) white (or) yellow cake mix

How To Make rhubarb strawberry upside-down cake

  • Step 1
    Place rhubarb in a greased 13 x 9 x 2-inch baking pan. Sprinkle both packages of strawberry gelatin over the rhubarb. Now place the mini marshmallows on top of the rhubarb.
  • Step 2
    Prepare cake mix according to package directions. (I used a white cake mix.)
  • Step 3
    Pour the cake batter over the marshmallows.
  • Step 4
    Bake the cake for 34 to 38 minutes. Use a toothpick inserted in the center of cake, and if it comes out clean, the cake is done. (I baked mine for 37 minutes.)
  • Step 5
    Allow cake to cool completely, before cutting and serving. If desired, top with Reddi Wip Whipped Topping.
  • Step 6
    *Note: Prep Time varies, since you'll need to cut, rinse, and trim the rhubarb. If using rhubarb that's been frozen, then thawed, prep time won't take as long.
