Ingredients

Scale
  • 4 cups fresh rhubarb, chopped into 1/2-inch pieces
  • 1 cup granulated sugar
  • 1 cup all-purpose flour
  • 1 box (15.25 oz) yellow cake mix (e.g., Duncan Hines or Betty Crocker)
  • 1 cup (2 sticks) unsalted butter, melted and slightly cooled
  • 1 teaspoon ground cinnamon (optional)
  • 1/4 teaspoon nutmeg (optional)
  • 1 teaspoon vanilla extract (optional)
  • Creamy vanilla ice cream, to serve

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with butter or nonstick spray.
  2. In a large bowl, toss the chopped rhubarb with 1 cup of granulated sugar. Let sit for about 10 minutes to draw out juice.
  3. In a separate bowl, combine the yellow cake mix, all-purpose flour, cinnamon, and nutmeg. Stir gently to distribute spices evenly.
  4. Spread the sugared rhubarb evenly across the bottom of the baking dish.
  5. Sprinkle the dry cake mixture evenly over the rhubarb without stirring or pressing down.
  6. Drizzle the melted butter slowly over the top, covering as much of the dry mix as possible.
  7. Bake for 45-50 minutes until the top is golden brown and the rhubarb is bubbly around the edges. A toothpick inserted near the center should come out with moist crumbs.
  8. Let the cake rest for 10-15 minutes before serving to thicken the juices.
  9. Serve warm with a generous scoop of creamy vanilla ice cream on top.

Notes

If using frozen rhubarb, thaw and drain excess liquid to avoid soggy topping. For gluten-free, substitute cake mix and flour with gluten-free versions. Butter can be replaced with coconut oil for dairy-free option. Rotate pan halfway through baking for even browning. Sprinkle extra sugar on top if rhubarb is very tart.
