Ingredients
Scale
- 4 cups chopped rhubarb (fresh or thawed frozen)
- 1 cup granulated sugar
- 1 box all-purpose yellow or white cake mix
- 1/2 cup (1 stick) unsalted butter, sliced thinly
- 1 teaspoon ground cinnamon
- 1 teaspoon vanilla extract (optional)
- 1/2 cup chopped nuts (pecans or walnuts, optional)
Instructions
- Preheat your oven to 350°F (175°C).
- Chop about 4 cups of rhubarb into 1/2-inch pieces. Toss with 1 cup granulated sugar and 1 teaspoon cinnamon in a mixing bowl. Let sit for 10 minutes to macerate.
- Transfer the rhubarb mixture to a 10 to 12-inch cast iron skillet and spread evenly.
- Sprinkle the dry cake mix evenly over the rhubarb without stirring.
- Slice 1/2 cup (1 stick) cold unsalted butter thinly and distribute evenly over the cake mix surface.
- Optionally, sprinkle 1/2 cup chopped nuts over the top.
- Bake in the preheated oven for 40 to 45 minutes until the topping is golden brown and crisp and the rhubarb is bubbly.
- Remove from oven and let cool for 10 to 15 minutes before serving.
Notes
If the topping browns too quickly, tent the skillet loosely with foil halfway through baking. Drain thawed frozen rhubarb well to avoid excess moisture. For gluten-free, use a gluten-free cake mix. For dairy-free, substitute butter with plant-based margarine or coconut oil. Serve warm with vanilla ice cream or whipped cream. Leftovers keep refrigerated up to 3 days and reheat well.
