I can’t resist sharing this recipe with friends and family, as it’s simple enough for anyone to master but feels absolutely special every time you enjoy it.
Ingredients You’ll Need
The beauty of Easy Lemon Squares lies not just in their flavor but in their simplicity. You’ll only need a handful of pantry basics and fresh lemons, but each ingredient plays an essential part—crisping the crust, making it melt-in-your-mouth tender, and giving the filling that gorgeous lemony brightness.
- Unsalted Butter (1 cup, softened): It creates a rich, tender foundation for your crust. Be sure your butter is soft for easy mixing!
- Granulated Sugar (1/2 cup for crust, 1 1/2 cups for filling): Adds gentle sweetness and balances out the tart lemon.
- All-Purpose Flour (2 cups for crust, 1/4 cup for filling): Gives the bars structure, both in the crispy base and the smooth lemon layer.
- Salt (1/4 teaspoon): Just a pinch brightens all the flavors and enhances the buttery notes.
- Large Eggs (4): Essential for binding the lemon filling and lending that satisfyingly creamy texture.
- Freshly Squeezed Lemon Juice (2/3 cup): The heart of these bars, giving them unmistakable tang and freshness—use real lemons for best results!
- Lemon Zest (1 tablespoon): Adds extra fragrance and a burst of fresh lemon oil without added acidity.
- Powdered Sugar (for dusting, optional): A snowy finish that looks beautiful and softens the tartness with each bite.
How to Make Easy Lemon Squares
Step 1: Prepare Your Pan and Preheat
Start by preheating your oven to 350°F (175°C), ensuring it’s ready when your batter is. Grease a 9×13-inch baking dish thoroughly, covering every corner, so your Easy Lemon Squares lift out perfectly after baking. This step is all about setting yourself up for success.
Step 2: Make the Buttery Crust
In a medium bowl, cream together the softened butter and 1/2 cup sugar until the mixture is light and fluffy. Add the flour and salt, mixing just until it forms a crumbly but cohesive dough. Press this mixture evenly across the bottom of your prepared pan—no need to fuss, just make sure the layer is smooth and even. Pop it in the oven for 18 to 20 minutes, or until the edges turn a gentle golden color.
Step 3: Whisk Up the Lemon Filling
While the crust bakes, grab a large bowl. Whisk together the eggs, remaining 1 1/2 cups sugar, 1/4 cup flour, lemon juice, and lemon zest. You want this mixture to be silky smooth and totally combined, so the finished filling is luscious and sets up beautifully in the oven. By now your whole kitchen should smell irresistibly citrusy!
Step 4: Pour and Bake
As soon as your crust comes out of the oven, immediately pour the lemon mixture over the hot crust. This helps the layers bond for super clean slices later. Return the pan to the oven and bake for 20 to 25 minutes—you’re aiming for a filling that’s set and doesn’t jiggle in the center when you gently shake the pan.
Step 5: Cool, Dust, and Slice
Let the bars cool completely in the pan; this patience pays off with neat squares and perfect texture. Once cooled, dust generously with powdered sugar. Use a serrated knife for the cleanest edges, and see those beautiful layers come to life as you slice your Easy Lemon Squares!
How to Serve Easy Lemon Squares
Garnishes
A classic flourish is a snowy dusting of powdered sugar, but you can also add a sprinkle of extra lemon zest or a few curls of candied lemon peel if you’re feeling fancy. A small mint sprig or edible flower on the plate makes each square look bakery-ready.
Side Dishes
For a breezy dessert tray, try pairing Easy Lemon Squares with plump fresh berries or a scoop of vanilla ice cream. They’re also delightful alongside a cup of tea, coffee, or even a lemonade for peak citrus goodness.
Creative Ways to Present
Cut your squares into triangles or diamonds for a playful twist, or arrange them on a tiered stand for a tea party vibe. For special occasions, try layering them with a dollop of whipped cream and blueberries in mini dessert glasses—fun, impressive, and so easy!
Make Ahead and Storage
Storing Leftovers
Keep any leftover Easy Lemon Squares in an airtight container in the refrigerator, where they’ll stay fresh and delicious for up to 5 days. The flavors actually meld and improve as they chill, making them even better on day two!
Freezing
To freeze, line a freezer-safe container with parchment and layer the squares (with a sheet of parchment between layers). They’ll keep for up to 3 months. When you’re ready for a treat, simply thaw them overnight in the fridge.
Reheating
If you like your Easy Lemon Squares just slightly warm, pop a piece in the microwave for 10 to 15 seconds. This revives the flavor and softens the crust just enough—though they’re equally divine straight from the fridge!
FAQs
Can I use bottled lemon juice instead of freshly squeezed?
Freshly squeezed lemon juice yields the brightest, freshest flavor. Bottled works in a pinch, but the taste won’t be quite as vibrant.
Why did my lemon filling turn out runny?
Usually, this happens if the bars are underbaked or if measurements were a bit off. Make sure to bake until the center is set and doesn’t wobble. Precise measuring (especially with flour and liquid) helps guarantee that perfect firm custard.
Can I add more lemon zest for a stronger flavor?
Absolutely! If you love a bold, tart flavor, increase the lemon zest or add a few drops of lemon extract. Just remember: zest adds aroma without making it more sour, while extract ramps up intensity quickly.
What’s the best way to cut Easy Lemon Squares cleanly?
Let them cool fully, even chilling in the fridge if you have time, and use a sharp serrated knife. Wipe the blade clean between cuts for perfect edges every time.
Can I make these gluten-free?
Yes! Swap all-purpose flour for your favorite cup-for-cup gluten-free blend. The result will be a slightly different crumb, but still delicious—just as easy and lemony as the original.

If you’re new to baking or just need a cheerful, dependable dessert in your rotation, Easy Lemon Squares deliver every single time. Their sunny flavor and effortless prep make them a must-try for anyone who loves classic, bright, crowd-pleasing treats. Give these a go—you’ll be passing the recipe on, too!
