For the Base:

- 1/2 cup (1 stick) unsalted butter, melted
- 1 large egg
- 1/4 cup fresh lemon juice
- 2 tablespoons lemon zest

Step-by-Step Instructions:
Step 1: Prepare Your Kitchen Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving some overhang for easy removal. Lightly grease the parchment with cooking spray.
Step 2: Create the Base Layer In a large mixing bowl, combine the cake mix, melted butter, one egg, 1/4 cup lemon juice, and 2 tablespoons lemon zest. Mix until just combined – the mixture will be thick and slightly crumbly. Press this mixture firmly into the bottom of your prepared pan using clean hands or the bottom of a measuring cup.
Step 3: Make the Creamy Topping In a separate bowl, beat the softened cream cheese until light and fluffy (about 2 minutes with an electric mixer). Add sugar and beat until smooth. Mix in the remaining egg, 2 tablespoons lemon juice, and 1 tablespoon lemon zest until well combined.
Step 4: Assemble and Bake Carefully spread the cream cheese mixture over the pressed cake mix base, using a spatula to create an even layer. Bake for 22-25 minutes, or until the edges are lightly golden and the center is set but still slightly jiggly.
Step 5: Cool and Serve Allow the bars to cool completely in the pan (about 2 hours) before lifting out using the parchment paper overhang. Cut into 16 squares and dust with powdered sugar if desired.
What to Serve Lemon Cake Mix Bars With:
These versatile bars pair beautifully with various accompaniments:
Hot Beverages: Serve alongside fresh coffee, Earl Grey tea, or chamomile tea for an afternoon treat. The citrus complements the warmth perfectly.
Fresh Fruits: Garnish with fresh berries like blueberries or raspberries for added color and complementary tartness. Sliced strawberries also create a lovely presentation.
Creamy Additions: A dollop of whipped cream or vanilla ice cream transforms these bars into an elegant dessert. For special occasions, try serving with lemon curd or mascarpone cheese.
Wine Pairings: These bars complement light wines like Moscato, Riesling, or Prosecco for adult gatherings.
Top Tips for Perfecting Lemon Cake Mix Bars:
Use Fresh Citrus for Maximum Flavor
Always use fresh lemon juice and zest rather than bottled versions. The oils in fresh zest provide incredible aroma and authentic taste that bottled alternatives simply can’t match.
Room Temperature Ingredients Work Better
Ensure your cream cheese and eggs are at room temperature before mixing. This prevents lumps and creates a smoother, more professional-looking topping layer.
Don’t Overbake
The center should still have a slight jiggle when you remove them from the oven. They’ll continue cooking from residual heat and firm up as they cool.
Press the Base Firmly
A well-compressed base layer prevents crumbling when cutting. Use the bottom of a measuring cup for even pressure across the entire surface.
Ingredient Substitutions
- No fresh lemons? Use 1 tablespoon lemon extract plus 1/4 cup water
- Want extra tang? Add 1 tablespoon sour cream to the topping
- Dairy-free option? Substitute cream cheese with dairy-free alternative
Storing and Reheating Tips:
Refrigerator Storage: Store covered bars in the refrigerator for up to 5 days. The cream cheese topping requires refrigeration for food safety.
Freezing Instructions: These bars freeze beautifully! Wrap individual bars in plastic wrap, then place in a freezer-safe container. Freeze for up to 3 months. Thaw overnight in the refrigerator before serving.
Serving Temperature: These bars taste best when served chilled or at room temperature. Remove from refrigerator 15-20 minutes before serving for optimal texture.
Make-Ahead Option: Prepare these bars up to 2 days in advance. They actually improve in flavor as the lemon notes meld together.

Frequently Asked Questions
Can I use a different cake mix flavor?
Absolutely! Vanilla, white, or even funfetti cake mix work wonderfully. Each creates a slightly different flavor profile while maintaining the same delicious results.
Why are my bars too crumbly?
This usually happens when the base layer isn’t pressed firmly enough or if you’ve overbaked them. Ensure you compact the base well and watch the baking time carefully.
Can I make these without cream cheese?
Yes! For a simpler version, skip the cream cheese layer and just bake the pressed cake mix base for 15-18 minutes. Add a simple lemon glaze after cooling.
How do I know when they’re done baking?
The edges should be lightly golden, and the center should be set but still have a slight jiggle. A toothpick inserted in the center should come out with just a few moist crumbs.
Can I double this recipe?
Certainly! Use two 9×13 pans or one large sheet pan. Adjust baking time accordingly – larger pans may need an extra 5-10 minutes.
What’s the best way to cut clean bars?
Use a sharp knife and wipe it clean between cuts. For extra-clean lines, chill the bars for 30 minutes before cutting.
Creative Variations to Try
Lemon Blueberry Bars: Fold 1/2 cup fresh blueberries into the cream cheese layer for bursts of fruity sweetness.
Coconut Lemon Bars: Add 1/4 cup shredded coconut to the base layer and sprinkle toasted coconut on top before baking.
Glazed Lemon Bars: Create a simple glaze with 1 cup powdered sugar, 3 tablespoons lemon juice, and 1 teaspoon vanilla. Drizzle over cooled bars.
Meyer Lemon Version: Use Meyer lemons for a sweeter, more floral citrus flavor that’s absolutely divine.
Lemon Lavender Bars: Add 1/2 teaspoon food-grade dried lavender to the base for an elegant, sophisticated twist.
