Ingredients
Scale
- 4 cups fresh rhubarb, chopped (about 500 grams)
- 1 cup granulated sugar (200 grams)
- 1 box yellow cake mix (15.25 ounces or about 432 grams)
- 1 cup unsalted butter, melted (2 sticks or 226 grams)
- Optional: 1 teaspoon vanilla extract
- Optional: pinch of cinnamon
Instructions
- Preheat your oven to 350°F (175°C).
- Wash and chop about 4 cups (500 grams) of fresh rhubarb into roughly 1/2-inch pieces. Toss it in a large bowl with 1 cup (200 grams) of granulated sugar. Let sit for 10 minutes to draw out juices.
- Transfer the rhubarb mixture to a greased 9×13-inch baking dish, spreading evenly.
- Sprinkle the dry yellow cake mix evenly over the rhubarb without mixing.
- Pour the melted unsalted butter slowly over the cake mix, covering as much as possible.
- Add optional vanilla extract or cinnamon if desired.
- Bake uncovered for 45 to 50 minutes until the topping is golden brown and the filling is bubbling.
- Cool slightly before serving.
Notes
If topping browns too quickly, tent with foil after 30 minutes. Let rhubarb sit with sugar to soften and reduce baking time. Pour melted butter evenly in a grid pattern to avoid dry or soggy spots. Can prepare ahead and refrigerate before baking, adding extra baking time if chilled.
