- 1 box (15.25 oz) lemon cake mix

How to Make Two-Ingredient Lemon Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C).
Lightly grease an 8×8-inch or 9×9-inch baking pan, then line it with parchment paper if desired for easier removal.
Step 2: Combine the Ingredients
In a large mixing bowl, add the lemon cake mix and lemon pie filling.
Stir until the two ingredients are completely combined and no large dry pockets of cake mix remain.
The batter will be thick and sticky. This is normal.
Step 3: Transfer to the Pan
Spread the batter evenly into the prepared baking pan.
Use a spatula or the back of a spoon to smooth the surface.
Step 4: Bake
Bake for approximately 25–30 minutes, or until the center is set and the edges are lightly golden.
A toothpick inserted into the center should come out with a few moist crumbs but not wet batter.
Step 5: Cool
Remove the pan from the oven and allow the lemon bars to cool completely before slicing.
Cooling helps the bars firm up and makes them easier to cut cleanly.
Step 6: Slice and Serve
Lift the cooled bars from the pan using the parchment paper if used.
Cut into squares or rectangles and dust lightly with powdered sugar if desired.
Tips for the Best Two-Ingredient Lemon Bars
- Use the exact size cake mix listed in the recipe for the best texture.
- Don't add extra liquid unless the batter is unusually dry.
- Spread the thick batter evenly in the pan.
- Don't overbake the bars or they can become dry.
- Let them cool completely before cutting.
- For cleaner slices, use a sharp knife and wipe it between cuts.
What Do Two-Ingredient Lemon Bars Taste Like?
These bars have a soft, tender texture with a sweet and tangy lemon flavor. The lemon cake mix provides sweetness and structure, while the lemon pie filling adds moisture and concentrated citrus flavor.
They're closer to a soft lemon cake bar than a traditional buttery shortbread-style lemon bar.
Can I Use Lemon Cake Mix?
Yes. Lemon cake mix provides the strongest citrus flavor and gives these bars their characteristic bright lemon taste.
If you prefer a slightly milder lemon flavor, a white or yellow cake mix can sometimes be used with lemon pie filling, although the final flavor and texture will be different.

Can I Make These Lemon Bars Ahead of Time?
Yes. These bars are convenient to make ahead because they can be prepared several hours before serving.
Allow them to cool completely, cover them, and store them appropriately until you're ready to serve.
How to Store Two-Ingredient Lemon Bars
Store the cooled lemon bars in an airtight container.
For longer storage, refrigerate them and allow them to come closer to room temperature before serving if you prefer a softer texture.
Can You Freeze Lemon Bars?
Yes. Once completely cooled, wrap individual bars tightly and place them in a freezer-safe container or bag.
Thaw them safely before serving and dust with fresh powdered sugar if desired.
Frequently Asked Questions
Can I use homemade lemon pie filling?
Yes. Homemade lemon pie filling can be used as long as it has a similar consistency and moisture level to prepared pie filling.
Why are my lemon bars too soft?
They may need additional baking time or more cooling time. The bars continue to firm as they cool, so allow them to cool completely before judging their final texture.
Why are my lemon bars dry?
Overbaking is the most common reason. Remove them once the center is set and the edges are lightly golden.
Can I double the recipe?
Yes. For a larger batch, use a larger baking dish and monitor the baking time carefully. A deeper layer may require additional time to bake through.
Can I add fresh lemon juice?
You can, but because this is designed as a two-ingredient recipe, additional liquid may change the texture. Fresh lemon zest is a safer way to increase lemon flavor without adding extra moisture.
Can I make these gluten-free?
Yes, provided you use a certified gluten-free lemon cake mix and gluten-free lemon pie filling.
