Notes

  • If you're unable to find fresh rhubarb, you can use frozen rhubarb. Be sure to fully thaw before using. 
  • This dump cake is very moist - be sure to fully bake and check the center with a knife. You want the knife to come out clean. 
  • Make sure to evenly pour the butter over the other ingredients in the baking dish. You want that melted butter to cover every bit of the top. It will give you the most beautifully browned and flavorful dump cake recipe ever!
  • If you are slicing your own rhubarb, make sure to discard the roots and leaves. The roots and leaves of rhubarb are not safe to eat.
