- 1 boxed cake mix, yellow
- 3 eggs
- 1/2 cup vegetable oil
- 1 cup water
- 3 cups diced rhubarb, frozen or fresh
- 1/4 cup orange juice
- 1 cup sugar
- 2 teaspoons orange zest
- 1 Tablespoon butter
Optional Powdered Sugar Glaze
- 2 cups powdered sugar, sifted
- 3-4 Tablespoons milk, cream or half and half
- 1 teaspoon vanilla extract
Preheat oven to 350 degrees F. Spray a 13 x 9 inch baking dish with nonstick cooking spray.
Prepare cake batter as directed on the box. Most yellow cake mixes require 3 eggs, 1/2 cup oil and 1 cup water. If you box's directions differ, follow the direction on the box.
Pour the prepared cake batter into the prepared baking dish; set aside.
In a small saucepan, heat rhubarb, orange juice and sugar to a simmer. Simmer for approximately 10 minutes or until thickened.
Remove from heat and stir in orange zest and butter.
Pour the rhubarb sauce over the prepared cake batter.
Bake for 30- 35 minutes or until set.
Cake can be eat as is or with optional glaze. To serve, cut the cake and flip slice over on a plate so the cake is on the bottom and the rhubarb sauce is on top. Scoop additional rhubarb over top if it sticks in the pan.
- This rhubarb cake uses boxed cake mix. I recommend a white or yellow cake mix. Follow the instructions on the box to prepare the batter.
- Substitute pineapple juice for orange juice, if desired.
- Use fresh or frozen rhubarb for this rhubarb spoon cake. If frozen is used, you may need to simmer the rhubarb sauce a bit longer to thicken it up.
- The powdered sugar glaze is completely optional. I like to make it because it makes the top of the cake prettier; however, it is a rhubarb upside down cake so it's served with the pretty rhubarb side up. Either way is great!
- To serve, cut the cake and flip onto the plate so the top becomes the bottom. If any additional rhubarb sauce remains in the dish, spoon over top.
