Lemon Blueberry Cheesecake Dump Cake
Five ingredients, one pan, zero stress — the summer dessert that disappears in minutes
I need you to understand something about this dessert before we get into it: it is wildly, embarrassingly easy to make. We are talking dump, mix, bake, done. No water baths. No springform pans. No cracks to worry about. No checking the internal temperature. Just a pan of something that tastes like a lemon blueberry cheesecake had a baby with a cobbler, and every single person who tries it asks for the recipe.
I started making dump cakes years ago because I needed a reliable party dessert that I could throw together in fifteen minutes and still look like I tried. This lemon blueberry version quickly became the one I come back to every summer. The cream cheese layer melts into the blueberries as it bakes and creates this custardy, cheesecake-like middle that is completely outrageous underneath that buttery golden cake top.
The trick — and this is important — is to not mix it. I know it looks wrong when you put it in the pan. You will want to stir it. Do not stir it. Let the layers do their thing and you will be rewarded with something that looks and tastes like you spent a lot more time on it than you did. Serve it warm with a scoop of vanilla ice cream and watch the whole thing disappear before you finish your own plate.

Juicy blueberries, tangy lemon, a creamy cheesecake layer, and a buttery golden cake top — all made in one pan with five ingredients. The easiest summer dessert you will ever make.
INGREDIENTS
2 cans (21 oz each) blueberry pie filling
1 box lemon cake mix (15.25 oz)
8 oz cream cheese, softened and cut into small cubes
½ cup (1 stick) unsalted butter, sliced into thin pats
1 lemon, zested (optional but highly recommended)
For serving:
Vanilla ice cream or fresh whipped cream
Fresh blueberries and lemon slices for garnish (optional)
STEPS
Preheat and prep: Preheat your oven to 350°F. Lightly grease a 9x13 inch baking dish with butter or non-stick spray. This helps the edges get golden and makes cleanup significantly easier.
Layer the blueberries: Pour both cans of blueberry pie filling into the bottom of the prepared baking dish and spread into an even layer. If you are using lemon zest, sprinkle it directly over the blueberry layer now. The zest at this layer infuses into the fruit as it bakes and makes the whole dessert smell like summer.
Add the cream cheese: Scatter the softened cream cheese cubes evenly over the blueberry layer. Try to distribute them as evenly as possible so every serving gets some of that cheesecake element. Do not press them in or mix them — just let them sit on top of the fruit.
Add the cake mix: Pour the dry lemon cake mix directly over the cream cheese and blueberry layers in an even layer. Do not mix. Do not stir. Just spread it evenly and move on. I know it looks like a construction site right now. Trust the process.
Add the butter: Place the butter pats evenly across the top of the dry cake mix, covering as much surface area as you can. The butter melts down through the cake mix as it bakes and creates the golden, slightly crispy top. Bare spots will look powdery when it comes out of the oven, so try to cover the surface well.
Bake: Bake at 350°F for 45 to 50 minutes, until the top is golden brown and the edges are bubbling. The center should look set — not wet or jiggly. If the top is getting too brown before the center is done, tent it loosely with foil for the last 10 minutes.
Rest and serve: Let the dump cake rest for at least 10 minutes before serving. It is molten straight from the oven. Serve warm with a scoop of vanilla ice cream or fresh whipped cream. The contrast of the warm cake with the cold ice cream is absolutely everything.
NOTES
Softened cream cheese is non-negotiable: If your cream cheese is cold and firm, it will not melt properly into the layers and you will end up with dense, unmelted chunks rather than that custardy cheesecake layer. Pull it out of the fridge at least an hour before you start, or microwave it in short bursts until it is soft and scoopable.
Butter coverage matters: The more evenly you cover the cake mix with butter, the more evenly it bakes. Any dry cake mix patches that do not get covered with butter will stay powdery on top. If you have gaps, add a few extra thin pats of butter or melt the full stick and drizzle it evenly over the top.
Fresh blueberries: If you want a fresher, less sweet version, you can do one can of blueberry pie filling plus 2 cups of fresh blueberries tossed with 2 tablespoons of sugar and 1 tablespoon of lemon juice. It gives the dessert a more natural, fruity flavor with a little less sweetness.
Cake mix swaps: Yellow cake mix works perfectly if you prefer a more neutral, buttery top. White cake mix keeps it lighter and lets the blueberry and lemon flavor come through more. Lemon is my favorite because the citrus runs through the whole dessert from top to bottom.
Storing leftovers: Cover and refrigerate for up to 4 days. Reheat individual portions in the microwave for 30 to 45 seconds. It is honestly really good cold too, eaten straight from the fridge the next morning with coffee. I will not tell anyone.
Make it for a crowd: This recipe doubles perfectly in a larger roasting pan. It is a genuinely great dessert for Fourth of July parties, summer cookouts, and potlucks because it travels well and is easy to serve straight from the pan.
FAQ
Do I really not need to mix this at all? Correct — do not mix it. The magic of a dump cake is in the layers. The butter melts down through the dry cake mix, the cream cheese melts into the fruit, and everything bakes into a cohesive dessert with distinct textures — a jammy fruity bottom, a creamy middle, and a golden buttery top. Stirring it would just turn it into a weird casserole. Hands off and trust the oven.
Can I use fresh or frozen blueberries instead of pie filling? You can use fresh or frozen blueberries, but the texture will be different. Blueberry pie filling is already thickened and sweetened, which helps the bottom layer stay jammy and saucy. If you use fresh or frozen berries, toss them with ¼ cup sugar, 2 tablespoons cornstarch, and 2 tablespoons lemon juice first to help them thicken as they bake. Otherwise the bottom will be watery.
Can I make this ahead of time? Yes. You can assemble the whole thing the night before, cover it tightly with plastic wrap, and refrigerate it unbaked. Pull it out about 20 minutes before baking to take the chill off, then bake as directed. You may need to add 5 to 10 minutes to the bake time since you are starting from cold.
What is the best way to serve this? Warm with vanilla ice cream is the unbeatable combination. The cold, creamy ice cream against the warm jammy cake is genuinely spectacular. Fresh whipped cream is a close second. You can also dust the top with powdered sugar right before serving if you want to make it look extra pretty for a party.
Can I make this with a different fruit? Absolutely. Strawberry pie filling with a white cake mix is a classic summer version. Cherry pie filling with chocolate cake mix is a crowd favorite in the fall and winter. Peach pie filling with white or yellow cake mix is incredible and very on-theme for summer. The formula is universal — two cans of pie filling, one box of cake mix, one stick of butter, and optionally cream cheese for the cheesecake layer.
Why does the top still look powdery in spots? Those spots did not get enough butter coverage before baking. It is purely a butter distribution issue and does not affect the flavor — just the texture of those spots on top. If you are halfway through baking and notice dry patches, carefully drizzle a little melted butter over those areas and continue baking. Problem solved.
