Unsalted butter: Using unsalted butter lets you control the salt level for balance and richness in your crust.
Graham crackers: These bring sweetness and texture; pulse them finely for a crust that packs together well without turning into mush.
Sugar: Adds just a touch of sweetness to your crust to counterbalance the tart filling.
Egg yolks: Give the filling its creamy consistency and help thicken it without baking it into a firm custard.
Sweetened condensed milk: The secret to smoothness and sweetness—plus, it pairs perfectly with lemon for that classic flavor you love.
Lemon juice: Fresh is best for that fresh, vibrant zing; bottled lemon juice won’t give you the same punch.

Tweak to Your Taste

One of the things I adore about this Creamy Lemon Squares Recipe is how easy it is to make it your own. Sometimes, I like to dial up the lemon for a punchier tang, other times I soften it with a sprinkle of powdered sugar on top. Play around with it based on your mood or the occasion!

More citrus zing: Add a teaspoon of lemon zest to the filling for a fragrant boost—I do this when I’m craving an extra lemony hit.
Low-sugar version: For a lighter sweet touch, reduce the sugar in the crust slightly and use a sugar-free substitute in the filling instead of sweetened condensed milk.
Seasonal twists: You can swap lemon juice for lime or even orange for a different but equally delicious citrus spin.

Step-by-Step: How I Make Creamy Lemon Squares Recipe

Step 1: Prepping the Crust

Start by breaking up your graham crackers into small pieces and tossing them into a food processor. Pulse until you have fine crumbs—almost like sand. Then, add the sugar and melted butter and pulse once more to combine. Press this mixture firmly into your prepared baking pan, making sure to bring it up about an inch along the sides. This creates the perfect sturdy base. Pop it in a 350°F oven for 10-12 minutes, watching carefully so it gets lightly browned but not burnt. Then, set it aside to cool. Cooling the crust fully is key so your filling sets up beautifully without mixing.

Step 2: Mixing the Creamy Lemon Filling

While your crust cools, whisk together the sweetened condensed milk and egg yolks until silky smooth—I usually use a handheld mixer, but a whisk works fine if you want to feel like a pro. Next, pour in your freshly squeezed lemon juice and whisk until everything’s blended in nicely. The mixture should be thick and creamy, not watery. Pour this gently over your cooled crust, then bake again at 350°F for about 15-20 minutes. You’re looking for the filling to be set but with a slight jiggle—think soft and creamy, not firm like a cheesecake.

Step 3: Cooling and Cutting

Once baked, let your creamy lemon squares cool completely in the pan on a wire rack. If you have the patience (or the time), refrigerate them after they reach room temperature—this step really helps firm them up, making clean, neat cuts a breeze. Thanks to the parchment paper hanging over the edges, lifting the whole block out of the pan is simple. Then slice into 16 mini squares or 9 larger pieces, depending on how big a bite you want.

Pro Tips for Making Creamy Lemon Squares Recipe

Press Crust Firmly: I press the graham crumb mixture tightly with the bottom of a glass for a crust that won’t crumble when you bite.
Cool Crust Completely: Letting the crust cool fully before adding filling prevents soggy bottom layers.
Check Filling Doneness: Take it out when the edges are set and the center still jiggles slightly—that’s perfect creaminess.
Use Fresh Lemon Juice: Bottled juice can make the flavor dull, so I always squeeze fresh lemons for a bright, fresh taste.

Garnishes

I like to keep things simple with these creamy lemon squares—just a light dusting of powdered sugar or some thin twisted lemon zest spirals for a bit of elegance. Sometimes, I accompany them with a dollop of lightly sweetened whipped cream for extra indulgence, especially if serving to guests.

Side Dishes

These squares are amazing on their own but also pair wonderfully with a cup of freshly brewed tea or a citrusy cocktail if you’re feeling fancy. For brunch, they’re a sweet note alongside fresh berries or a light fruit salad.

Creative Ways to Present

For parties, I’ve layered these lemon squares on a tiered dessert tray alongside mini cupcakes and macarons—it adds a beautiful pop of color and texture. You can cut them into tiny bite-sized pieces and serve on decorative toothpicks for easy finger food, perfect for social gatherings.

Make Ahead and Storage

Storing Leftovers

I always store leftover lemon squares in an airtight container in the fridge. They keep beautifully for up to 4 days—though honestly, mine rarely last that long! Keeping them chilled helps maintain their creamy texture and keeps the crust crisp.

Freezing

Freezing works if you want to prep ahead. I wrap individual squares tightly in plastic wrap and then place them in a freezer bag. They can keep for up to 2 months. When ready to eat, thaw overnight in the fridge for the best results.

Reheating

I prefer to enjoy lemon squares chilled, so I usually skip reheating. But if you want to warm them slightly, a quick 15-second zap in the microwave softens the texture without melting the filling. Just be cautious not to overheat and lose that creamy consistency.

FAQs

Can I use a different citrus instead of lemon in this recipe?

Absolutely! Lime juice works wonderfully as a tart substitute, offering a slightly different but equally delicious flavor. Orange juice can also be used, though it will create a sweeter, less tangy filling. Keep in mind that the acidity level affects how the filling sets, so you might need to adjust baking time slightly.
Why is my lemon filling rubbery after baking?

This often happens if the filling is overbaked. To avoid a rubbery texture, bake just until the edges are set and the center has a slight jiggle. The filling will firm up more as it cools and chills. Using only egg yolks, like in this recipe, helps keep it tender.
How do I get clean cuts when slicing lemon squares?

Let your squares cool completely, then chill them in the fridge for an hour or more. Use a sharp knife wiped clean between each cut to prevent sticky smears. Removing the squares from the pan using parchment paper “handles” is key for easy slicing and serving.
Can I make these lemon squares vegan or dairy-free?

While this recipe relies on condensed milk and butter, you can experiment by substituting coconut condensed milk and vegan butter alternatives. Keep in mind that texture and flavor might vary, so try a small batch first to see how you like it.

I can’t tell you how many times this Creamy Lemon Squares Recipe has brought a smile to my friends and family’s faces.
