How to Make rhubarb dump cake

Prepare Your Oven and Dish: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray for easy cleanup.

Mix the Rhubarb Filling: In a large bowl, combine chopped fresh rhubarb with sugar and cinnamon if using. Toss until well-coated; this will create a deliciously sweet tart filling.

Add Cake Mix Topping: Evenly spread cake mix over the rhubarb mixture in your baking dish. Don’t worry about mixing; we want that lovely layered effect.

Pour on Butter: Drizzle melted butter evenly over the cake mix layer. It creates a golden crust that’s simply irresistible when baked.
