Strawberry Rhubarb Dump Cake (The Easiest Cozy Dessert You’ll Ever Bake)
When a home suddenly craves something sweet, warm, and comforting, but nobody feels like measuring, mixing, or washing a pile of dishes, this Strawberry Rhubarb Dump Cake is the answer. It’s the kind of nostalgic dessert that feels like it came straight from a family kitchen—simple ingredients, minimal effort, and unbelievably satisfying results.
What makes this dessert irresistible is the contrast of textures and flavors. Beneath the surface lies a bubbling layer of sweet strawberries and tangy rhubarb, rich and jammy as it bakes. On top forms a golden, buttery cake crust that becomes crisp around the edges and tender in the middle. The magic happens right in the baking dish—no mixing bowls required.
True to its name, you simply dump, sprinkle, drizzle, and bake. In under an hour, your kitchen fills with the warm aroma of baked fruit and butter, and the result is a dessert that tastes like it took far more effort than it actually did.
Ingredients for Strawberry Rhubarb Dump Cake
Each ingredient plays an important role in creating the perfect balance of flavor and texture.
1. Strawberry Rhubarb Pie Filling (2 cans, 20–21 oz each)
The star of the dessert. This filling creates the sweet-tart fruit layer that bubbles beneath the cake topping. The strawberries provide sweetness and vibrant color, while rhubarb adds a refreshing tartness that keeps the dessert from becoming overly sugary.
2. Yellow Cake Mix (1 box, about 15.25 oz)
The shortcut that makes this recipe effortless. When sprinkled dry over the fruit and baked with butter, the mix transforms into a crispy, golden crust with soft cake-like pockets underneath.
3. Unsalted Butter (½–1 cup, melted)
Butter is what brings everything together. As it melts into the cake mix during baking, it creates a rich, crumbly topping that’s buttery and slightly crisp—almost like a cobbler crust.
4. Nonstick Cooking Spray or Butter (for greasing)
A light coating keeps the fruit layer from sticking and helps the dessert scoop easily from the dish.
Step-by-Step Instructions
1. Preheat the Oven
Set your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with nonstick spray or butter.
2. Add the Fruit Layer
Open both cans of strawberry rhubarb pie filling and dump them directly into the prepared dish. Spread the filling evenly so it reaches all corners.
3. Sprinkle the Cake Mix
Evenly sprinkle the dry yellow cake mix over the fruit layer. Try to cover the filling completely, forming a smooth, even layer. Do not mix—the layers should stay separate.
4. Drizzle the Butter
Slowly drizzle the melted butter across the entire surface of the cake mix. Aim to moisten as much of the mix as possible. A few dry spots are perfectly fine—they’ll turn crisp and crumbly during baking.
5. Bake the Cake
Place the baking dish on the center rack and bake for 35–45 minutes. The dessert is ready when the top becomes golden brown and slightly crisp and the fruit filling is bubbling around the edges.
6. Let It Rest
Allow the cake to cool for 10–15 minutes before serving. This short rest helps the fruit filling thicken and makes scooping easier.
7. Serve and Enjoy
Scoop generous portions into bowls and enjoy while warm.

2. Cover Dry Cake Mix Spots
If you notice large dry patches before baking, lightly drizzle a bit more butter over them.
3. Add Crunch with Nuts
Sprinkle ½ cup chopped pecans or sliced almonds over the cake mix before adding butter.
