Ingredients You’ll Need
Here’s everything you’ll need to make these easy lemon bars. I’ve grouped them by layer to keep things simple.
For the Shortbread Crust:
- 1 cup unsalted butter, melted
- 2 cups all-purpose flour
- ½ cup powdered sugar
- ¼ tsp salt
- 1 tsp vanilla extract (optional, but adds depth)
Tip: Make sure your butter is fully melted for the easiest mixing!
For the Lemon Filling:
- 1½ cups granulated sugar
- ¼ cup all-purpose flour
- 4 large eggs, at room temperature
- 2/3 cup fresh lemon juice (from about 3–4 lemons)
- 1 tbsp lemon zest (zest before juicing!)
- Optional: 1 tbsp milk for extra creaminess
For Dusting:
- Powdered sugar, to dust before serving
Ingredient Substitutions
Don’t have everything on hand? Here are a few swaps you can try:
- Salted butter instead of unsalted: Just omit the added salt in the crust.
- Bottled lemon juice: Not ideal, but okay in a pinch. Add extra zest for brightness.
- Gluten-free flour: Use a 1:1 gluten-free blend for a celiac-friendly version.
- Coconut sugar in place of granulated: It’ll add a deeper flavor and darker color.
- Almond extract instead of vanilla: Just a drop can add a twist!
How to Make Lemon Bars
Follow these steps and you’ll have bright, citrusy lemon bars cooling on your counter in under an hour!
1. Preheat and Prep (5 minutes)
- Preheat your oven to 350°F (175°C).
- Line a 9×13 inch baking pan with parchment paper, leaving some overhang for easy lifting.
2. Make the Shortbread Crust (10 minutes)
- In a mixing bowl, combine melted butter, flour, powdered sugar, salt, and vanilla.
- Stir until it forms a soft dough.
- Press evenly into the prepared pan. Use the bottom of a measuring cup for a smooth, flat surface.
3. Bake the Crust (18–20 minutes)
- Bake until the crust is just starting to turn golden around the edges.
- Remove from the oven and let it cool slightly while you make the filling.
4. Mix the Lemon Filling (5 minutes)
- In a large bowl, whisk together sugar and flour.
- Add the eggs, lemon juice, and zest. Whisk until smooth and slightly frothy.
5. Pour and Bake (20–22 minutes)
- Pour the filling over the warm crust.
- Return to the oven and bake until the center is set and doesn’t jiggle, about 20 minutes.
6. Cool & Chill (1–2 hours)
- Let the bars cool at room temperature, then chill in the fridge for at least 1 hour for clean slicing.
7. Slice and Dust (5 minutes)
- Use the parchment overhang to lift the bars out.
- Slice with a sharp knife, wiping between cuts.
- Dust with powdered sugar before serving.

Expert Tips and Common Mistakes to Avoid
- Use room temperature eggs: They mix more evenly and help the filling set better.
- Don’t overbake: If the top starts to brown, they’re likely overdone. Look for a set but pale top.
- Zest before juicing: It’s way easier and avoids squishy lemons.
- Chill before cutting: This helps the filling firm up, so your bars cut cleanly.
- Use a glass or ceramic pan: Metal pans can give a metallic tang to citrus desserts.
Common mistake: pouring filling onto a cold crust—this can cause it to separate.
Variations & Add-Ons
- Gluten-Free: Use a 1:1 gluten-free flour blend in both crust and filling.
- Dairy-Free: Substitute vegan butter (like Earth Balance) in the crust.
- Meyer Lemon Bars: Swap in Meyer lemons for a sweeter, floral flavor.
- Lavender Lemon Bars: Add a pinch of dried culinary lavender to the crust.
- Coconut Crust: Replace ½ cup flour with shredded coconut for a tropical twist.
- Berry Swirl: Drop small spoonfuls of raspberry jam on top before baking and swirl gently.
Serving Suggestions
These bars are lovely on their own but can be dressed up, too:
- Dust with powdered sugar just before serving for that bakery-style finish.
- Serve alongside whipped cream or a scoop of vanilla ice cream.
- Pair with tea or lemonade for a refreshing afternoon treat.
- Display on a white platter lined with parchment paper for a classic, clean look at parties.
Storage & Reheating
Refrigeration:
- Store lemon bars in an airtight container in the fridge for up to 5 days.
- Place parchment between layers if stacking.
Freezing:
- Wrap bars individually in plastic wrap, then freeze in a zip-top bag.
- They’ll keep for up to 3 months.
- Thaw overnight in the fridge before serving.
Reheating:
- Lemon bars are best served chilled or at room temperature—no reheating needed!

Frequently Asked Questions
Can I use bottled lemon juice for lemon bars?
Yes, you can use bottled lemon juice in a pinch, but fresh lemon juice and zest give the best flavor and brightness.
Why did my lemon bars come out runny?
If your lemon bars are runny, they may be underbaked or the filling wasn’t mixed thoroughly. Make sure the center is set and slightly firm before removing them from the oven.
Do lemon bars need to be refrigerated?
Yes, lemon bars should be refrigerated because of the egg-based filling. Store them in an airtight container for up to 5 days.
Can I freeze lemon bars?
Absolutely! Wrap the bars individually in plastic wrap, then place them in a freezer bag. They can be frozen for up to 3 months. Thaw overnight in the fridge before serving.
How do I cut lemon bars cleanly?
For clean slices, chill the bars completely, then use a sharp knife and wipe the blade clean between each cut. This helps avoid a sticky mess.
Why is my lemon bar crust too soft or soggy?
A soggy crust usually means the crust wasn’t baked long enough before adding the filling. Make sure it’s lightly golden around the edges before pouring the lemon mixture on top.
