For the Crust:
-
1 box yellow cake mix (about 15 oz)
-
1 large egg
-
½ cup unsalted butter, melted
For the Filling:
-
8 oz cream cheese, softened
-
2 large eggs
-
1 teaspoon vanilla extract
-
1 tablespoon fresh lemon juice
-
1 teaspoon lemon zest
-
1 box powdered sugar (about 16 oz)
-
1 stick (½ cup) unsalted butter, melted
-
1 cup fresh blueberries (or frozen, thawed and drained)
Directions
Preparing the Crust:
-
Preheat the oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan, or line it with parchment paper for easy removal.
-
Make the crust: In a medium bowl, combine the cake mix, egg, and melted butter. Stir until well combined and a dough forms. The dough will be thick.
-
Press into the pan: Press the cake mixture evenly into the bottom of the prepared baking pan to form the crust. It should cover the entire bottom of the pan.
Preparing the Filling:
-
Beat the cream cheese: In a separate large bowl, beat the softened cream cheese with an electric mixer until smooth and creamy.
-
Add the eggs, vanilla, lemon juice, and zest: Add the eggs, vanilla extract, lemon juice, and lemon zest, and beat until the mixture is smooth and well combined.
-
Add powdered sugar and butter: Gradually add the powdered sugar, beating continuously until smooth. Then, mix in the melted butter.
-
Fold in the blueberries: Gently fold in the fresh blueberries, making sure they are evenly distributed throughout the filling mixture.
Assembling the Cake:
-
Pour the filling over the crust: Pour the blueberry lemon filling mixture over the prepared crust, spreading it out evenly with a spatula.
-
Bake the cake: Place the cake in the preheated oven and bake for 40-50 minutes, or until the center is set and slightly golden around the edges. The top will be firm, but the center should still be soft and gooey.
-
Cool the cake: Allow the cake to cool in the pan for at least 30 minutes, then transfer to the refrigerator to chill for 2-3 hours (or overnight) to let the filling set completely.
Serving:
Cut the cake into squares and serve chilled. You can garnish it with extra fresh blueberries or a dusting of powdered sugar for an extra touch of elegance.

FAQs
Can I use frozen blueberries instead of fresh?
Yes, frozen blueberries work just as well as fresh. Be sure to thaw and drain them well before folding them into the filling to avoid excess liquid in the cake.
Can I make this cake ahead of time?
Yes! In fact, this cake benefits from sitting in the refrigerator for a few hours to allow the flavors to meld and the filling to set properly. It’s perfect for making ahead for parties or gatherings.
How do I know when the cake is done?
The cake is done when the edges are golden brown and the center is set but still slightly gooey. You can gently shake the pan—if the center is still a little wobbly but firm to the touch, it’s ready.
Can I use a different cake mix flavor?
Yes, you can experiment with different cake mix flavors. A vanilla or lemon cake mix would work well, depending on your preference.
How can I make the cake less sweet?
If you prefer a less sweet cake, you can reduce the powdered sugar in the filling by about ¼ cup, but the filling’s texture might change slightly.
