Ingredients
For the lemon layer:
-
Lemon curd or lemon pie filling (about 21 ounces / 595 grams total)
For the cake layer:
-
Yellow or butter cake mix (one standard box, about 13.25 to 15.25 ounces / 375 to 432 grams) – do not use lemon-flavored cake mix, as it can make the dessert too tart
For the cream cheese layer:
-
Cream cheese (8 ounces / 226 grams), cut into small cubes and softened to room temperature
For the buttery top:
-
Unsalted butter (½ cup / 113 grams), cold and sliced into thin pats
Optional for serving:
-
Vanilla ice cream or whipped cream
Instructions
Preheat and Prep
Preheat your oven to 350°F (175°C). Grease an 8×8-inch or 9×9-inch square baking dish with nonstick spray or butter.
Layer the Lemon
Spread the lemon curd or lemon pie filling evenly across the bottom of the prepared baking dish.
Add the First Cake Layer
Sprinkle half of the dry cake mix (about 1⅓ cups) evenly over the lemon layer. Do not stir — just let it sit on top.
Add the Cream Cheese
Scatter the cubes of softened cream cheese evenly over the cake mix layer.
Add the Second Cake Layer
Sprinkle the remaining half of the dry cake mix evenly over the cream cheese.
Top with Butter
Arrange the cold butter slices evenly over the top of the cake mix, covering as much surface area as possible. The butter is what creates that golden, crisp, crumbly topping.
Bake
Bake for about 40 minutes, until the top is golden brown and the edges are bubbly. The center should be set but still slightly soft.
Cool and Serve
Let the cake cool for at least 15 minutes before serving. It is delicious warm, at room temperature, or even chilled. Serve with a scoop of vanilla ice cream or a dollop of whipped cream for extra indulgence.
The Magic Behind It
The cake mix and butter form a crisp, crumbly topping that bakes into something almost like a streusel. Beneath that, the cream cheese melts into the lemon layer, creating a creamy, cheesecake-like filling. The lemon provides a bright, tangy contrast to the rich butter and cream cheese, making every bite perfectly balanced.
Pro Tips
-
Use cold butter — it melts slowly in the oven, creating a flakier, crunchier topping
-
Make sure the cream cheese is softened to room temperature so it melts smoothly into the filling
-
Do not stir the layers — the magic of a dump cake is in the distinct layers
-
Use yellow or butter cake mix, not lemon, to avoid an overly tart dessert
-
Let the cake rest after baking so the layers can set properly before serving
Upgraded Version: Creamy Cheesecake-Style Filling
For a richer, smoother cream cheese layer, try this quick upgrade:
Beat the softened cream cheese with one egg, half a cup of powdered sugar, a pinch of salt, and the zest of one lemon until smooth and fluffy. Spread this mixture over the lemon layer before adding the cake mix. This gives you an even more pronounced cheesecake texture and flavor.
Variations
-
Blueberry lemon – add a layer of fresh or frozen blueberries between the lemon and cream cheese
-
Raspberry lemon – scatter fresh raspberries over the lemon layer for a tart, fruity twist
-
Key lime version – substitute key lime pie filling for the lemon
-
Coconut lemon – sprinkle shredded coconut over the top before baking
-
Gluten-free – use a gluten-free yellow cake mix and ensure your lemon curd is gluten-free
Storage
Refrigerate leftovers in an airtight container for up to five days. This dessert is wonderful cold, but you can also reheat individual portions in the microwave for a few seconds. Freeze for up to three months — thaw overnight in the refrigerator before serving.
Common Questions
Can I use lemon-flavored cake mix?
It is not recommended — it can make the dessert overwhelmingly tart. Yellow or butter cake mix provides the best balance.
What if I don’t have lemon curd?
You can use lemon pie filling, or make a quick substitute by whisking one box of instant lemon pudding mix with two cups of milk and using that as your lemon layer.
Can I make this in a larger pan?
Yes — a 9×13-inch pan works too, but the layers will be thinner and baking time may be shorter. Start checking at the 30-minute mark.
Why is my top not crispy?
The butter may not have been cold enough, or it was not distributed evenly. Next time, use cold butter and cover the surface as much as possible.
Can I add a glaze on top?
Absolutely — a simple powdered sugar glaze drizzled over the cooled cake adds extra sweetness and a beautiful finish.
This lemon cream cheese dump cake is proof that simple ingredients can create something extraordinary. It is bright, creamy, buttery, and absolutely irresistible — the kind of dessert that disappears before you even sit down. Enjoy every tangy, sweet bite.
