Rhubarb Cake at The Happy Housewife

My friend Barb gave me some rhubarb last week along with this delicious recipe for rhubarb cake. I have never eaten rhubarb in my life, but this cake is good enough to make anyone a rhubarb fan!

Rhubarb can be chopped and frozen in an airtight bag to be used for later. It grows year round in warm climates and can be grown in a large pot if you don’t have space for a garden.


Rhubarb Cake

This cake was soooo easy to make. It took less than 5 minutes to prepare (minus the cooking time) and was loved by everyone! It would be perfect for a potluck or dinner party as the prep time is minimal and you only use one dish!


  • 4 cups chopped rhubarb
  • 1 3/4 cup sugar
  • 1 small box strawberry Jello
  • 1 box yellow or white cake mix
  • 2 cups warm water
  • 1 cup butter, melted


  1. In a 9×13 pan place rhubarb in the bottom.
  2. Evenly sprinkle the sugar over the top of the rhubarb.
  3. Then sprinkle the Jello over the sugar, and the cake mix over the Jello.
  4. Pour water over everything, then pour the butter on the top.
  5. Bake at 350 degrees for one hour or until the top is golden brown and the rhubarb is bubbling through.
  6. Serve warm with cool whip or ice cream.

    This looks very similar to a recipe that our family calls Dump Cake…

    1 can cherry pie filling
    1 can crushed pineapple
    1 box yellow cake mix
    1 1/2 sticks butter

    Dump canned fruit into 13 x 9. Dump cake mix evenly on top. Distribute butter slices on top of everything. Bake for 1 hr. @ 350. Serve hot or cold.

    It’s a great throw-together dessert for heading out. Not at all healthy, but good for an occasional treat, I suppose.

  2. We have so much rhubarb growing in our yard. I’ll have to try this.

  3. my grandma used to make this! If you’re looking for more rhubarb recipes, stop by — I’ve got a whole bunch! Our new favorite: rhubarb gingersnap cheesecake!

  4. Is it really 2 cups of butter…that seems like an awful lot.

      Oh my goodness! Thank you for catching that error! It is 2 sticks of butter, or 1 cup!!! So sorry about that.
