Ingredients
- 1 package (15.25 ounces) yellow cake mix
- ½ cup (1 stick) unsalted butter, melted
- 1 can or jar (20 ounces) lemon pie filling or lemon curd
Directions
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C).
Grease a 9×13-inch baking dish lightly or line it with parchment paper for easy removal and cleanup.
Step 2: Create the Crumb Mixture
In a large bowl, combine the dry cake mix and melted butter.
Stir until the mixture forms coarse crumbs resembling damp sand.
Step 3: Form the Crust
Transfer about two-thirds of the crumb mixture into the prepared baking dish.
Press it firmly into an even layer to create the base of the bars.
Step 4: Add the Lemon Layer
Spread the lemon filling evenly over the crust, making sure it reaches all corners of the pan.
Step 5: Add the Topping
Sprinkle the remaining crumb mixture over the lemon layer.
The topping doesn’t need to completely cover the filling; some lemon peeking through creates a beautiful appearance.
Step 6: Bake
Place the pan in the oven and bake for 25 to 30 minutes.
The bars are ready when the crumb topping is lightly golden and the lemon filling is set.
Step 7: Cool Completely
Allow the bars to cool fully before slicing.
For the cleanest cuts, refrigerate them for at least one hour before serving.
Helpful Baking Tips
Press the Crust Firmly
A well-packed crust helps the bars hold together and prevents crumbling when sliced.
Don’t Overbake
Removing the bars once the topping turns lightly golden helps maintain a soft, tender texture.
Use Quality Lemon Filling
Since the filling provides most of the flavor, choosing a high-quality lemon curd or pie filling will noticeably improve the final result.
Chill Before Cutting
Refrigerating the bars before slicing creates cleaner edges and a firmer texture.
Delicious Variations

Mix freshly grated lemon zest into the filling before baking for a brighter citrus taste.

- Raspberry filling

for a fruity twist.
Different Cake Mix Options

- White cake mix

to customize the flavor.

Frequently Asked Questions
Can I use a different cake mix?
Yes. White, vanilla, or lemon cake mix all work well. Yellow cake mix provides a rich, buttery flavor, but feel free to experiment with other varieties.
Is lemon curd a good substitute for lemon pie filling?
Absolutely. Lemon curd creates a richer, more intense citrus flavor, while lemon pie filling tends to be sweeter and thicker.
Why are my bars falling apart?
The crust may not have been packed firmly enough, or the mixture may need a little more melted butter. Make sure the base is pressed tightly before baking.
Why is the filling too soft?
The bars likely need more cooling time. Lemon fillings continue to set as they cool, so wait until they reach room temperature or chill them before slicing.
How can I tell when they’re finished baking?
Look for lightly golden crumbs on top and a filling that appears mostly set with only slight movement in the center.
Can I prepare them ahead of time?
Yes. In fact, many people prefer them after they’ve chilled for several hours, allowing the flavors to develop.
How should they be stored?
Keep them in an airtight container:
- At room temperature for up to 2 days
- In the refrigerator for up to 1 week
Can they be frozen?
Yes. Wrap individual bars tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before serving.
Can I make them less sweet?
You can balance the sweetness by adding fresh lemon zest or using a tart lemon curd instead of a sweeter pie filling.
