Easy Lemon Cream Cheese Bars Recipe
Tangy filling and tender base come together for an easy, bakery-quality treat.

There’s something magical about the combination of tangy lemon and rich cream cheese that makes these lemon cream cheese bars absolutely irresistible. This foolproof recipe takes a brilliant shortcut by using boxed cake mix for the base, creating a dessert that tastes like it came from a bakery but requires minimal effort in your own kitchen.
These bars feature a tender, cake-like bottom layer that provides the perfect foundation for a lusciously gooey cream cheese filling infused with bright lemon flavor. The result is a dessert that strikes the ideal balance between sweet and tart, with a texture that’s both satisfying and indulgent.
What Makes This Recipe Special
The genius of this lemon cream cheese bars recipe lies in its simplicity and reliability. By starting with a boxed lemon or yellow cake mix, you eliminate the guesswork that often comes with making dessert bars from scratch. The cake mix provides consistent results every time, ensuring your bars have the perfect texture and flavor base.
The cream cheese layer is where the magic really happens. Unlike traditional lemon bars that rely solely on eggs and lemon juice for their filling, these bars incorporate cream cheese, which adds richness and creates that signature gooey texture that makes them so addictive. The combination of fresh lemon zest and juice provides a bright, citrusy flavor that cuts through the richness beautifully.
Essential Ingredients Breakdown
Success with this recipe starts with understanding each ingredient’s role in creating the perfect texture and flavor profile.
For the Base Layer
The foundation of these bars consists of just three simple ingredients. One 15.25-ounce box of lemon or yellow cake mix provides the structure and flavor base. While lemon cake mix enhances the citrus theme, yellow cake mix works equally well and allows the fresh lemon in the filling to take center stage.
Half a cup of melted salted butter binds the cake mix together and adds richness. Using salted butter provides a subtle flavor enhancement that complements both the lemon and cream cheese components. One large egg helps bind the mixture and contributes to the tender texture of the base.
For the Cream Cheese Filling
The star of the show is one 8-ounce block of cream cheese at room temperature. This is crucial – cold cream cheese will create lumps and won’t incorporate smoothly with the other ingredients. Room temperature cream cheese blends effortlessly, creating a silky, smooth filling.
Four cups of powdered sugar might seem like a lot, but it’s necessary to achieve the proper sweetness level and consistency. Powdered sugar dissolves more easily than granulated sugar, contributing to the smooth texture of the filling.
Three additional large eggs provide structure to the filling and help it set properly during baking. Fresh lemon zest and juice from one lemon deliver the bright, tangy flavor that makes these bars so appealing. The zest contains oils that provide intense lemon flavor, while the juice adds tartness and helps balance the sweetness.
Two teaspoons of vanilla extract enhance all the other flavors and add depth to the overall taste profile. A few drops of liquid yellow food coloring are optional but can enhance the visual appeal of the bars, giving them a more vibrant, sunny appearance.
Step-by-Step Preparation Guide
Preparing Your Pan and Oven
Begin by preheating your oven to 350°F, which provides the ideal temperature for both layers to bake properly without overcooking. Proper pan preparation is crucial for easy removal of the finished bars. Lightly grease a 9-by-13-inch baking pan with butter, then line it with parchment paper, leaving a 1-inch overhang on two sides. This overhang will serve as handles for lifting the bars out of the pan once they’re cooled. Butter the parchment paper as well to prevent any sticking.
Creating the Base Layer
Using a stand mixer fitted with the paddle attachment ensures the best results, though a large bowl and wooden spoon will work in a pinch. Combine the cake mix, melted butter, and one egg, mixing on medium-low speed for about 30 seconds until the ingredients are just combined. The mixture will look crumbly and somewhat dry – this is exactly what you want.
Press this mixture firmly into the bottom of your prepared pan, creating an even layer. Use your hands or the bottom of a measuring cup to ensure the base is uniformly distributed and well-compacted. This creates a stable foundation for the cream cheese layer.
Preparing the Cream Cheese Filling
Clean your mixing bowl thoroughly before preparing the filling – any residual cake mix could create lumps in your smooth cream cheese layer. Beat the room-temperature cream cheese on low speed until it’s completely smooth, about one minute. This initial beating eliminates any lumps and creates the silky base for your filling.
Gradually add the powdered sugar, beating until well combined, approximately one minute. Increase the mixer speed to medium-high and beat until the mixture becomes fluffy, which takes about 2 to 3 minutes. This step incorporates air into the filling, contributing to its light, gooey texture.
Reduce the speed back to low and add the remaining three eggs one at a time, ensuring each is fully incorporated before adding the next. Beat in the lemon zest, lemon juice, vanilla extract, and food coloring if you’re using it. The filling should be smooth, creamy, and beautifully lemony.
Assembly and Baking
Pour the cream cheese mixture over the pressed cake mix base, spreading it evenly to ensure uniform baking. Don’t worry if the filling seems thin – it will set beautifully during baking. Bake for 45 to 50 minutes, until the top develops a golden color and a shiny crust. The center should be set but still slightly jiggly when you gently shake the pan.
Cooling and Serving Instructions
Patience is crucial at this stage. Allow the bars to cool completely in the pan set on a wire cooling rack for at least 2 hours. This cooling time allows the filling to set properly and makes cutting much easier. For even cleaner cuts, you can refrigerate the cooled bars for an additional hour.
When ready to serve, gently lift the bars out of the pan using the parchment paper as handles. Place them on a cutting board and use a sharp knife to slice into 20 squares – make 5 slices along the long side and 4 slices along the short side. Clean your knife between cuts for the neatest appearance.
Just before serving, dust the bars generously with powdered sugar using a fine-mesh sieve. This final touch adds visual appeal and a little extra sweetness that complements the tart lemon flavor beautifully.
Storage and Make-Ahead Tips
These lemon cream cheese bars are incredibly versatile when it comes to storage and planning ahead. At room temperature, store the bars in an airtight container for up to 3 days. However, wait to dust with powdered sugar until just before serving, as the sugar can absorb moisture and lose its visual impact over time.
For longer storage, these bars freeze exceptionally well for up to 3 months. Wrap individual bars in plastic wrap or store them in a freezer-safe container with parchment paper between layers. Thaw at room temperature for about 30 minutes before serving.
If you want to make these bars ahead for a special occasion, prepare them completely, cool and cut them, then store them covered in the refrigerator overnight. This actually improves the texture slightly, as the flavors have more time to meld together.
Recipe Variations and Substitutions
While this recipe is perfect as written, there are several ways to customize it to your preferences or dietary needs. For a more intense lemon flavor, increase the lemon zest to 2 tablespoons and add an extra tablespoon of lemon juice. You can also substitute lime zest and juice for a tropical twist.
For those who prefer less sweetness, reduce the powdered sugar in the filling to 3½ cups. The bars will still set properly but will have a more pronounced tangy flavor. Adding a pinch of salt to the cream cheese mixture can also help balance the sweetness and enhance the overall flavor profile.
If you don’t have a lemon or yellow cake mix on hand, vanilla cake mix works as an excellent substitute. You can also experiment with other citrus flavors by using orange or lime cake mix paired with matching zest and juice.
Troubleshooting Common Issues
If your bars turn out too soft or don’t set properly, the most common culprit is underbaking. Make sure to bake until the top is golden and has developed that characteristic shiny crust. The center should be set but can still have a slight jiggle when gently shaken.
Lumpy cream cheese filling usually results from using cold cream cheese or not beating it thoroughly before adding other ingredients. Always ensure your cream cheese is at room temperature and beat it until completely smooth before proceeding with the recipe.
If your bars crack during cooling, they may have been overbaked or cooled too quickly. Try reducing the baking time slightly and allow them to cool gradually at room temperature before refrigerating.
