This Rhubarb Dump Cake is so easy, it literally requires no mixing! Just dump all the ingredients in the cake pan by layers and watch the cake/crisp do it's magic in the oven


  • 4-5 cups chopped rhubarb
  • 1/2 cup sugar
  • 1 box of yellow cake
  • 2 sticks of butter, cut into cold cubes


  1. In a greased glass 9 x 9 pan, lay the rhubarb and sugar in the pan.
  2. Over the rhubarb and sugar layer, sprinkle the cake mix over the top.
  3. Slice the butter into small cubes the size of tablespoon. Then place the butter evenly over the dry cake mix. 
  4. Bake at 350 for 40 - 60 minutes or until golden & crispy on top.

The butter can make the cake a little gooey right as you take it out of the oven. It is best to let the cake sit out for awhile to set to prevent that from happening.
