Step-by-Step Instructions
Preheat oven to 350°F (175°C) and grease a 9×13-inch baking dish.
Mix the rhubarb and sugar in a large bowl until evenly coated.
Spread the rhubarb mixture evenly into the prepared baking dish.
Sprinkle the cake mix over the rhubarb layer.
Drizzle melted butter evenly across the cake mix.
Bake for 45–50 minutes, or until the top is golden brown and the rhubarb is bubbling.
Cool slightly before serving.
🔥 Pro Tip: Want a crispier topping? Add an extra drizzle of melted butter over the cake mix before baking.
