Instructions

  1. Preheat oven to 350° F (175° C). Spray a 9x13 inch pan with baking spray or 7x12 or 2 quart casserole dish.
  2. Lay fresh or frozen (unthawed) rhubarb 4-6 cups rhubarb (optional strawberries 1-2 cups strawberries) in the bottom of the dish, sprinkle the sugar 3/4 cup sugar evenly over the top, then the cornstarch 2 tablespoons cornstarch and nutmeg ¼ teaspoon nutmeg. Gently combine to coat the rhubarb.
  3. Next, evenly sprinkle the cake mix 1 box cake mix over the rhubarb, DO NOT MIX! Use your fingers to even out the cake mix a little bit.
  4. Then drizzle the melted butter 3/4 cup butter over the remaining dry parts of the cake mix.
  5. Bake at 350° F (175° C) for 45 minutes, until golden and bubbly. If at this time there are still some dry cake mix patches, gently push them into the liquid using the back of a spoon – baking for an additional 15 minutes until the cake is golden brown if needed. Bake a little longer at high altitude.
  6. I enjoy this fresh fruit dessert warm with ice cream, my husband likes it refrigerated with fresh whipped cream. Enjoy with a scoop of vanilla ice cream or a dollop of whipped cream.
