This lemon cream cheese dump cake combines the tangy brightness of fresh lemon with the richness of cream cheese for an incredibly moist, flavorful dessert that comes together with minimal effort. The delightful contrast between the fluffy cake layer and creamy bottom has made this my go-to dessert for both casual family dinners and special occasions.
I discovered this recipe during a particularly hectic holiday season when I needed something impressive but simple. The first time I served it my mother in law actually asked for the recipe believing it was a complicated layered dessert that took hours to prepare.
Ingredients
- Cream cheese: softened to room temperature for at least 1 hour ensures a perfectly smooth texture without lumps
- Granulated sugar: provides the ideal sweetness that balances the tangy lemon
- Large eggs: act as binding agents and create richness in the cream cheese layer
- Fresh lemon juice: brightens the entire dessert use real lemons for the best flavor
- Lemon zest: contains essential oils that provide intense citrus flavor always zest before juicing
- Lemon cake mix: forms the convenient top layer and adds consistency to results
- Water: helps activate the cake mix and creates proper batter consistency
- Vegetable oil: adds necessary fat to the cake layer ensuring moistness
- Optional toppings: like whipped cream and fresh fruit elevate presentation
Step-by-Step Instructions
- Preheat Oven:
- Set your oven to 350°F and thoroughly grease your baking dish making sure to get into all corners and up the sides to prevent sticking. A light coating of flour after greasing provides extra insurance against sticking for this layered dessert.
- Prepare Cream Cheese Base:
- Beat the softened cream cheese and sugar together for a full 3 minutes until the mixture becomes noticeably lighter in color and completely smooth. Scrape down the sides of the bowl several times during mixing to ensure no pockets of unmixed cream cheese remain.
- Incorporate Eggs:
- Add the first egg and beat for 30 seconds before adding the second egg. This gradual incorporation creates a silkier texture in the finished cream cheese layer. The mixture should become slightly more fluid but still maintain body.
- Add Lemon Flavoring:
- Pour in the fresh lemon juice and sprinkle the zest evenly throughout the mixture. Stir just until combined about 15 seconds to distribute the citrus flavors without overmixing which can make the cream cheese layer too loose.
- Create Cake Batter:
- In a separate bowl combine the cake mix water and oil using a whisk to break up any clumps. Mix for about 2 minutes until the batter has a consistent texture but avoid overmixing which can make the cake tough.
- Layer Components:
- Spread the cream cheese mixture evenly across the bottom of your prepared baking dish smoothing to the edges with a spatula. Then carefully pour the cake batter over the top working from the outside edges toward the center to maintain distinct layers.
- Bake To Perfection:
- Place the baking dish on the center rack of your preheated oven and bake for the full time watching for the top to turn golden brown. The surface should spring back slightly when touched and a toothpick inserted into the cake layer should come out clean.

The fresh lemon zest is truly the secret weapon in this recipe. I once made it without zest when I ran out of lemons and while still good the depth of citrus flavor was noticeably diminished. My family now knows the cake is coming when they see me zesting lemons in the kitchen and start hovering in anticipation.
Perfect Storage Method
This cake actually improves with a day of resting in the refrigerator as the flavors meld together beautifully. Cover tightly with plastic wrap or transfer to an airtight container and refrigerate for up to 5 days. The cream cheese layer makes this cake unsuitable for room temperature storage beyond serving time. If you need to make it further ahead consider freezing individual portions wrapped tightly in plastic wrap then foil for up to 3 months. Thaw overnight in the refrigerator for best texture results.
Smart Substitution Options
This versatile recipe welcomes creative adaptations while maintaining its signature texture. Try swapping the lemon cake mix for vanilla and adding 2 teaspoons of lemon extract for a more subtle lemon flavor. Lime juice and zest create a delightful variation perfect for summer gatherings. For a more decadent version add 1 cup of white chocolate chips to the cream cheese mixture before baking. Those watching sugar intake can use a sugar free cake mix and reduce the granulated sugar to 2/3 cup with good results.
Seasonal Serving Suggestions
In summer top chilled slices with fresh blueberries or raspberries for a beautiful color contrast and complementary flavor. Fall calls for a light dusting of cinnamon sugar on top before serving warm. Winter holidays become special with a dollop of cranberry whipped cream. Spring celebrations shine with candied lemon slices and edible flowers as garnish. For extra indulgence drizzle slices with a simple glaze made from powdered sugar and lemon juice just before serving.
