Step-by-Step Instructions: How to Make Lemon Squares
1. Prepare Your Pan and Preheat the Oven
- Preheat your oven to 350°F (175°C)
- Line your 9×13 inch baking pan with parchment paper, leaving an overhang on two sides for easy removal
- Lightly grease the parchment paper with butter or cooking spray
- Set the prepared pan aside while you make the crust
2. Make the Shortbread Crust
- In a large mixing bowl, combine 2 cups flour, ½ cup sugar, and ¼ teaspoon salt
- Cut the softened butter into small cubes and add it to the flour mixture
- Using a pastry cutter, fork, or your hands, work the butter into the flour until the mixture resembles coarse crumbs
- Press the mixture evenly into the bottom of your prepared pan, making sure it reaches all corners
- Use the bottom of a measuring cup to pack the crust down firmly and create an even layer
3. Bake the Crust
- Place the pan in the preheated oven and bake for 20 minutes
- The crust should be lightly golden around the edges but not completely browned
- Remove from the oven but leave the oven on
- Let the crust cool slightly while you prepare the filling (about 5 minutes)
4. Prepare the Lemon Filling
- In a medium bowl, whisk together the 4 eggs until well beaten and slightly frothy
- Add 2 cups sugar and whisk until the mixture is smooth and the sugar begins to dissolve
- Stir in â…“ cup flour until completely incorporated with no lumps
- Add the fresh lemon juice and lemon zest, whisking until the filling is smooth and uniform in color
- Let the mixture sit for 2-3 minutes to allow any remaining air bubbles to rise to the surface
5. Pour and Bake
- Carefully pour the lemon filling over the warm crust, spreading it evenly with a spatula if needed
- Gently tap the pan on the counter a few times to release any air bubbles
- Return the pan to the oven and bake for 25 minutes
- The filling should be set around the edges but still slightly jiggly in the center when done
- Avoid overbaking, as this can cause cracks and a tough texture
6. Cool and Cut
- Remove the pan from the oven and place it on a cooling rack
- Allow the lemon squares to cool completely at room temperature (about 1 hour)
- Once cooled, refrigerate for at least 2 hours or overnight for the cleanest cuts
- Use the parchment paper overhang to lift the entire sheet out of the pan onto a cutting board
- Cut into 16 equal squares using a sharp knife, wiping the blade clean between cuts
- Dust generously with powdered sugar using a fine-mesh sieve just before serving

Tips for The Best Lemon Squares
These simple tricks will help you achieve bakery-quality results every single time. I’ve learned these through years of experimentation and a few less-than-perfect batches.
- Use room temperature ingredients: Let your butter and eggs sit out for 30 minutes before starting for better texture
- Don’t skip the parchment paper: This makes removal and cutting so much easier
- Zest before juicing: It’s much easier to zest whole lemons than juiced ones
- Chill before cutting: Cold lemon squares cut cleaner with no messy edges
- Clean your knife between cuts: Wipe the blade with a damp cloth for neat, professional-looking squares
- Sift your powdered sugar: This prevents clumps and gives you that beautiful, snowy finish
- Check for doneness carefully: The center should still have a slight jiggle when you remove them from the oven

Health Benefits of Key Ingredients
While lemon squares are definitely a treat, they do contain some ingredients with nutritional benefits. Understanding what goes into your desserts helps you make informed choices.
Lemons are packed with vitamin C, which supports immune function and helps your body absorb iron. They also contain antioxidants that may reduce inflammation and support heart health.
Eggs provide high-quality protein and essential nutrients like vitamin D, B12, and choline. They help with brain function and eye health while keeping you satisfied longer.
Butter offers fat-soluble vitamins A, D, E, and K that your body needs for various functions. When used in moderation, it adds richness and helps you feel satisfied with smaller portions.

FAQs About Lemon Squares
1. Why are my lemon squares runny?
The filling needs adequate baking time to set properly. If your squares are runny, they likely need more time in the oven or weren’t fully cooled before cutting.
Make sure you’re measuring the flour correctly and not overbaking the crust, which can cause the filling to bake unevenly. Always chill them completely before cutting for the best texture.
2. Can I use bottled lemon juice instead of fresh?
Fresh lemon juice tastes significantly better and gives you that bright, authentic citrus flavor. Bottled juice often contains preservatives that can affect the taste and texture of your squares.
If you absolutely must use bottled juice, choose 100% pure lemon juice without additives. However, I strongly recommend taking the extra few minutes to juice fresh lemons for the best results.
3. How do I prevent cracks in my lemon squares?
Cracks usually form when the filling is overbaked or cooled too quickly. Remove the pan from the oven when the center still has a slight jiggle, as it will continue cooking from residual heat.
Let them cool gradually at room temperature instead of placing them directly in the refrigerator. Gentle cooling prevents the dramatic temperature change that causes cracking.
4. Can I double this recipe?
Absolutely! This recipe doubles beautifully for larger gatherings. Use two 9×13 inch pans or one large sheet pan (approximately 12×17 inches).
Keep in mind that baking time may increase slightly for a thicker layer in a sheet pan. Check for doneness by looking for that slight jiggle in the center.
5. Why is my crust soggy?
A soggy crust happens when the crust isn’t baked long enough before adding the filling. Make sure your crust is lightly golden and firm to the touch before pouring in the lemon mixture.
Also, avoid letting the baked crust cool completely before adding the filling, as the contrast between a cold crust and hot filling can create condensation. Add the filling while the crust is still warm for the best results.
