how to make Easy Rhubarb Dump Cake

Ingredients:

  • 4 cups fresh rhubarb stalks, chopped (about 1 lb)
  • 1 to 1 1/4 cups granulated sugar
  • 1 box (15.25 oz) yellow cake mix
  • 1 cup (2 sticks) unsalted butter, melted
  • 1 teaspoon ground cinnamon (optional)
  • 1 teaspoon vanilla extract (optional)

Directions:

  1. Preheat your oven to 350°F (175°C).
  2. Wash and chop about 4 cups of fresh rhubarb into 1/2-inch pieces. Toss them in a mixing bowl with 1 to 1 1/4 cups granulated sugar and 1 teaspoon ground cinnamon if using. Stir gently to coat the rhubarb evenly. Let it sit for 10 minutes.
  3. Spread the sugared rhubarb mixture evenly in a 9×13 inch baking dish, making sure the juice is distributed.
  4. Sprinkle the dry yellow cake mix evenly over the rhubarb. Do not stir.
  5. Pour 1 cup (2 sticks) melted unsalted butter evenly over the cake mix, drizzling it in a pattern to cover as evenly as possible.
  6. Bake uncovered in the preheated oven for 45–50 minutes until the top is golden brown and the rhubarb filling is bubbling around the edges. If the top browns too quickly, loosely tent with foil.
  7. Remove from oven and let cool slightly for 15 minutes before serving.
