Ingredients

Scale
  • 3 cups chopped fresh rhubarb (about 375 g), 1-inch pieces
  • 3 cups hulled and halved fresh strawberries (about 450 g)
  • 1 cup granulated sugar (200 g)
  • 1 tablespoon lemon juice
  • 1/2 teaspoon ground cinnamon (optional)
  • 1 box yellow cake mix (about 15.25 oz or 432 g)
  • 1 cup unsalted butter, melted (about 225 g)

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. In a large mixing bowl, combine chopped rhubarb, halved strawberries, granulated sugar, lemon juice, and ground cinnamon if using. Toss gently to coat all fruit pieces evenly.
  3. Spread the fruit mixture evenly across the bottom of a 9×13-inch baking dish.
  4. Sprinkle the boxed yellow cake mix evenly over the fruit layer without stirring.
  5. Melt the unsalted butter and drizzle it slowly and evenly over the cake mix layer.
  6. Bake for 45-50 minutes until the topping is golden brown and crispy and fruit juices are bubbling around the edges. Tent with foil if topping browns too quickly.
  7. Cool for at least 15 minutes before serving to allow juices to thicken.

Notes

Do not stir after layering the cake mix on top to maintain a crisp crumble topping. Use fresh or thawed fruit and drain excess liquid to avoid a runny base. Tent with foil if topping browns too quickly. Let the cake rest before serving to thicken juices. Optional: add chopped nuts like walnuts or pecans on top before baking for extra crunch.
