Aunt Carrie brought this to every winter get-together because it travels well and always gets compliments. One pan, big payoff. This blueberry dump cake is the kind of dessert you can throw together in minutes, tuck into the backseat, and serve warm at a church potluck or family game night. It uses pantry-friendly shortcuts—blueberry pie filling, a box of yellow cake mix, and a stick (or two) of butter—but comes out looking like something you fussed over all afternoon. The edges bubble up deep purple, the top turns golden and crumbly, and there’s always someone asking for the recipe before the pan is scraped clean.

Serve this blueberry dump cake warm, scooped straight from the pan into bowls. A scoop of vanilla ice cream or a dollop of whipped cream melts into the hot berries and crunchy topping and makes it feel extra special. It pairs nicely with simple, cozy meals like roast chicken, chili, or a big pot of soup—anything you’d serve on a cold night when everyone wants to linger at the table. For gatherings, set the pan on a trivet on your kitchen counter with a big serving spoon and let folks help themselves; keep extra napkins handy because the juicy blueberry filling can be delightfully messy.

Servings: 8-10

2 cans (21 ounces each) blueberry pie filling

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with nonstick cooking spray or a thin layer of butter. This helps the edges release easily and keeps cleanup simple for traveling.

Spread the blueberry pie filling evenly in the bottom of the prepared baking dish. Use a spatula or the back of a spoon to nudge it into the corners so you get those pretty, deep purple bubbling edges when it bakes.

Sprinkle the dry yellow cake mix evenly over the blueberry pie filling. Don’t mix it in—just shake the pan gently or use your hand to level the cake mix into an even layer so it bakes up into a golden, crumbly topping.

Lay the thin slices of butter evenly over the surface of the dry cake mix, covering as much of the top as possible. If you’re using the extra melted butter, drizzle it over any dry spots. This helps the cake mix absorb the butter and turn crisp and golden instead of powdery.

Place the baking dish on the middle rack of the preheated oven. Bake for 40–50 minutes, or until the top is deep golden brown and the blueberry filling is bubbling up around the edges. The center should look set, not wet or floury.
