Creamy Lemon Squares are the perfect balance of tangy and sweet, offering the bright flavor of lemon without the fuss of meringue or a traditional pie crust. With a buttery graham cracker base and a smooth, luscious lemon filling, these squares are a no-fuss dessert ideal for summer, holidays, or any time you need a citrusy pick-me-up. Quick to prepare and easy to serve, they bring the same satisfaction as a classic lemon pie but in a more manageable, handheld form.
I first discovered the magic of these creamy lemon squares while hosting a small family gathering. I wanted a dessert that looked elegant but didn’t require complicated techniques or fancy tools. The buttery crust baked quickly, while the velvety lemon filling set perfectly after a short chill. Watching everyone take their first bite and see their faces light up was unforgettable—the tangy sweetness and creamy texture won over both kids and adults alike. From that day, these squares became my go-to treat for any occasion.

For the crust, graham cracker crumbs, sugar, and melted butter are all you need. Use 10–12 full graham crackers to yield about 1½ cups of crumbs. The butter adds richness and helps bind the crumbs together, while the sugar enhances the natural sweetness. Lightly butter the baking dish for extra non-stick security and an added touch of flavor.
Forming and Baking the Crust
Combine the graham cracker crumbs, sugar, and melted butter until the mixture resembles wet sand. Press it evenly into an 8-inch square baking pan, extending about 1 inch up the sides. Bake at 350°F (175°C) for 8–12 minutes until lightly golden and set. Cooling the crust completely is crucial before adding the lemon filling to prevent it from melting or becoming soggy.
Crafting the Lemon Filling
Mixing the Ingredients
The filling combines egg yolks, sweetened condensed milk, and fresh lemon juice. Whisk until smooth and slightly thickened. Optionally, add lemon zest for an extra burst of citrus aroma. The egg yolks add richness and help the filling set, while the sweetened condensed milk gives it a creamy, velvety texture without needing additional cream.
Assembling and Baking
Pour the lemon mixture over the cooled crust and gently tilt the pan to spread evenly. Bake for 15 minutes, just until the filling is set but still creamy—overbaking will curdle the custard. The gentle cooking ensures a silky, luxurious texture that melts in your mouth.
Chilling and Serving
Cooling Properly
Allow the lemon squares to cool on a wire rack for 30 minutes, then transfer to the refrigerator to chill for at least 1 hour (longer for firmer squares). Use the parchment overhang to lift the slab out of the pan before slicing. Wiping your knife with a damp towel between cuts ensures clean, smooth edges for presentation.
Presentation Ideas
Dust the top with powdered sugar, garnish with thin lemon slices or zest, and serve alongside fresh berries or whipped cream. These little touches elevate the dessert and make it visually appealing. Pair with iced tea or sparkling water for a refreshing finish, perfect for a summer gathering or casual dessert.
Tips, Storage, and Variations
Storage Tips
Store the squares in an airtight container in the fridge for up to 5 days. They can also be frozen for up to 3 months; thaw in the fridge before serving. Proper chilling ensures the filling sets fully and the flavors develop beautifully.
Why This Recipe Works
Gently baking the filling ensures there are no raw eggs in the final product, creating a safe and creamy texture. The graham cracker crust remains firm yet buttery, providing the ideal contrast to the tangy lemon topping. Using fresh lemon juice rather than bottled guarantees a bright, zesty flavor that defines this dessert.
Optional Variations
Add a thin layer of whipped cream on top for an extra indulgent treat. For a more pronounced lemon flavor, increase the zest to two lemons or incorporate a touch of limoncello. These small tweaks personalize the dessert while keeping the core creamy, tangy experience intact.
