Ingredients
  

- 4 cups chopped rhubarb (fresh or frozen)

- 1 cup granulated sugar

- 1 box yellow or white cake mix

- 1 cup water (or orange juice for flavor boost)

- ½ cup melted butter

- (Optional) 1 tsp vanilla extract

- (Optional) ½ tsp ground cinnamon

- (Optional) 1–2 cups sliced strawberries

- (Optional) ½ cup chopped pecans or almonds

Method
 

  1. 1. Preheat your oven to 350°F (175°C).
    2. Lightly grease a 9x13-inch baking dish with butter or non-stick spray.
    3. Spread the chopped rhubarb evenly across the bottom of the dish.
    4. Sprinkle granulated sugar evenly over the rhubarb layer.
    5. Pour the dry cake mix directly on top of the sugar—do not stir.
    6. Drizzle water (or orange juice) evenly across the dry mix to moisten.
    7. Pour the melted butter evenly over the surface of the cake mix.
    8. Add optional toppings like cinnamon, vanilla, strawberries, or nuts if desired.
    9. Bake uncovered for 40–45 minutes, or until the top is golden brown and the edges are bubbling.
    10. Let rest for 5 minutes before serving. Enjoy warm with ice cream or whipped cream!

- Reheat in the microwave or oven and serve with a scoop of vanilla ice cream for best results.
