Simple Ingredients for Fresh Blueberry Dump Cake
- Butter: Use cold, salted butter cut into thin pats to cover the top of the cobbler-like recipe. This will bring rich flavor with plenty of moisture. I prefer salted butter, but you can use unsalted butter.
- Blueberries: I used fresh blueberries, rinsed and patted dry, but you may also use frozen blueberries; do not thaw!
- Cake mix: Make the cakey base with a box of lemon cake mix – or use white, vanilla, yellow cake mix, or another flavor of boxed cake mix.
- Lemon: Get authentic lemon flavor with the zest and juice from one fresh lemon.
- Vanilla: Add pure vanilla extract. Try my easy Homemade Vanilla recipe!

How to Make a Blueberry Dump Cake
Step 1 | Preheat and prep
Begin by preheating the oven to 350° F (175° C) and coat a 9×13-inch baking or 2 quart baking dish with cooking spray or spray oil.
Step 2 | Add fresh fruit
Next, add the fresh berries to the baking dish, shaking it to even them out. Sprinkle the fresh lemon zest over the blueberries and squeeze the lemon juice on top. This is optional but you can use a large spoon to toss.
Step 3 | Top with cake mix and butter
Now, sprinkle the box of cake mix into the baking dish in an even layer. Do NOT STIR.
Then, slice the cold butter into very thin pats, about ⅛ inch thick, and place them on top to cover as much of the surface as possible.
Fresh Tips
- If you prefer a thicker cobbler dump cake, use a smaller baking dish.
- It helps to slice the butter when it’s cold. Then, place the pats in the freezer until you add them to the recipe.
- If you’re using a cake mix that contains pudding, the cake will not cook all the way through– the top will be crusty, and the middle will be extra gooey. It’s not quite like the original recipe, but it’s still delicious and perfectly safe to eat!
Step 4 | Bake, cool, and serve!
Bake for 35 to 50 minutes. When the top is golden brown and the inside is bubbly, remove the dish and let it cool for 10 to 15 minutes. Then, serve the warm or cooled to room temperature.
Top it with homemade whipped cream or a scoop of old fashioned vanilla ice cream or this lemon gelato recipe– Enjoy!

Crockpot Blueberry Lemon Dump Cake
I love recipes that can be made different ways, whether you need the oven space for other things during a Spring holiday or you don’t want to turn the oven on in the summer, you can adapt this recipe easily to the crockpot.
- Spray a 4-7 quart crockpot with spray oil or rub with butter.
- Layer ingredients as described in the recipe, fresh blueberries, lemon zest, lemon juice, vanilla extract and cake mix.
- Slice pats of butter and lay evenly over the top.
- Lay a clean tea towel* or paper towels over the top of the crockpot and cover. *The tea towel will absorb any condensation that may drip onto the cake.
- Cover and cook the dump cake for 3 hours on HIGH, or 5-6 hours on LOW.
Variations & Substitutions
Frozen Berries: If you prefer, use frozen blueberries instead of fresh, but don’t thaw them. You may need to bake the dish a little longer. If the top is browning quickly and the berries are not bubbly, loosely cover the baking dish with foil.
Extra Sweet Blueberry Dump Cake: The sweet blueberries add plenty of sweetness, in my opinion. However, you can make this treat extra sweet by tossing up to ¼ cup of granulated sugar with the berry mixture.

Blueberry Pineapple Dump Cake: Add a can of drained crushed pineapple to the blueberry mixture for more fruity goodness!
Add-Ins: Try adding toasted nuts, coconut flakes, or even white chocolate chips.
Adjust the Butter: Use more or less butter on top of the cake mix, depending on your preference. When you use less, there may be more dry cake mix areas – Either add more butter 15 minutes before removing the dish from the oven or gently press the dry areas into the moist mixture below. It’s delicious with more or less butter, so the choice is yours!
