How to Make Easy Rhubarb Dump Cake

Ingredients

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

Directions

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with butter or nonstick spray.
In a large bowl, toss the chopped rhubarb with 1 cup of granulated sugar. Let it sit for about 10 minutes to draw out the juice.
In a separate bowl, combine the yellow cake mix, all-purpose flour, cinnamon, and nutmeg. Stir gently to mix the spices evenly.
Spread the sugared rhubarb evenly across the bottom of the baking dish.
Sprinkle the dry cake mixture evenly over the rhubarb without stirring or pressing down.
Drizzle the melted butter slowly over the top, covering as much of the dry mix as possible.
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.
Let the cake rest for 10-15 minutes before serving to thicken the juices.
Serve warm with a generous scoop of creamy vanilla ice cream on top.

How to Serve Easy Rhubarb Dump Cake

Serve this dump cake warm straight from the baking dish. A big scoop of creamy vanilla ice cream on top adds a delightful creaminess to the tangy rhubarb. You can also sprinkle some extra cinnamon on top for added flavor.

How to Store Easy Rhubarb Dump Cake

Tips to Make Easy Rhubarb Dump Cake
