This Easy Blueberry Dump Cake is a simple, delicious dessert that requires minimal effort and delivers big flavor. With fresh or frozen blueberries layered beneath a buttery golden cake mix topping, it bakes to a perfect balance of juicy fruit and moist cake in under an hour. Ideal for busy nights or last-minute gatherings, this dessert is easy to assemble and pairs wonderfully with vanilla ice cream or whipped cream.

Ingredients

Fruit

  • 3 cups fresh or frozen blueberries (if using frozen, no need to thaw)

Dessert Topping

  • 1 (16.25 ounce) box golden butter cake mix (yellow or white works, too)
  • ½ cup unsalted butter (thinly sliced)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C). Lightly spray a 9×13 inch baking pan or glass dish with non-stick cooking spray to ensure the cake won’t stick.
  2. Layer Ingredients: Evenly distribute the blueberries across the bottom of the prepared pan. Then, sprinkle the dry cake mix evenly over the top of the blueberries. Finally, place the thin slices of unsalted butter evenly over the surface of the cake mix, covering as much as possible to allow the butter to melt and create a crispy, golden crust.
  3. Bake: Place the pan in the preheated oven and bake for 45-50 minutes. Bake until the top is golden brown and the cake is cooked through.
  4. Cool and Serve: Remove the cake from the oven and allow it to cool for about 10 minutes. This resting time helps the dessert set and makes it easier to serve. For the best indulgence, serve warm with vanilla ice cream or whipped cream on the side.

Notes

  • You can use fresh or frozen blueberries – no need to thaw if frozen.
  • If desired, substitute the cake mix with another flavor for variation.
  • Butter should be sliced thinly to ensure even melting and browning on top.
  • Letting the cake cool slightly helps it set and makes serving easier.
  • Pairs excellently with vanilla ice cream, whipped cream, or your favorite topping.
