Getting ready to make these lemon bars couldn’t be easier since the ingredients are straightforward yet each plays an essential role. From the crisp, flaky shortbread base that provides crunch and richness to the tangy lemon curd that offers that signature zesty kick, every element works together beautifully to create a harmonious dessert.

3/4 cup plain flour (all-purpose flour): Provides structure and a tender crumb for the shortbread base.
1/4 cup rice flour (or cornstarch/cornflour): Adds extra lightness and delicate texture to the crust.
1/2 cup icing sugar / powdered sugar, sifted: Sweetens the base gently without overpowering its buttery flavor.
1/4 tsp salt: Enhances all the flavors and balances the sweetness perfectly.
110g / 1 stick unsalted butter, cold and cubed: The star of the base, creating that rich, crumbly texture.
3 large eggs (55-60g/2oz each): Binds and adds richness to the lemon curd topping.
1 cup caster sugar / super-fine sugar: Sweetens the lemon curd smoothly for the perfect tang-to-sweet ratio.
2 tbsp plain flour (all-purpose flour): Thickens the lemon curd so it sets without cracks or wrinkles.
1 tbsp lemon zest: Packed with essential oils, it adds intense, fresh lemon aroma and flavor.
1/2 cup lemon juice (2–3 lemons): Provides the bright, refreshing sourness that defines this dessert.

How to Make Easy Lemon Bars Recipe

Step 1: Prepare the Shortbread Base

Begin by preheating your oven to 180C/350F (160C fan). Grease an 8-inch square baking tin and line it with parchment paper, making sure to leave an overhang for easy removal later. In a food processor fitted with the standard “S” blade, pulse the flours, icing sugar, salt, and cold butter cubes together about 5 to 10 times until the mixture resembles coarse sand. If you don’t have a processor, using your fingertips to rub the butter into the dry ingredients works just as well. Pour this sandy mixture into your lined tin, then press it down firmly and evenly, using the back of a spoon or a flat tool to ensure it’s packed well and reaches the edges.

Step 2: Bake the Base

Pop your prepared crust into the oven and bake for about 20 minutes, or until the edges turn a warm golden brown and the center appears pale golden. This step is vital for a crust that both supports the lemon topping and has a satisfying buttery crunch. Don’t let it cool once it’s out — you’ll want to pour the lemon curd right on top while the base is still warm to help everything set beautifully.

Step 3: Mix the Lemon Curd

While your crust is baking, whisk together the eggs, caster sugar, flour, lemon zest, and freshly squeezed lemon juice until fully combined. The flour helps the lemon curd set properly without becoming rubbery, while the zest and juice give it that fresh, vibrant lemon flavor we all crave.

Step 4: Bake the Lemon Topping

When the crust comes out of the oven, immediately pour your lemon curd mixture evenly over the warm shortbread. Return the pan to the oven and bake for another 20 minutes. You want the topping to be set but still just a little soft to the touch—this guarantees a creamy texture instead of something overly firm. It’s important not to overbake, or the curd can dry out, losing that luscious quality.

Step 5: Cool and Chill

Once baked, take the bars out and let them cool at room temperature for about an hour before transferring them to the fridge for at least two hours. This chilling time is key to allowing the lemon curd to firm up perfectly, making slicing into neat squares a breeze. When ready, dust generously with icing sugar for that classic bakery-finished look and a little extra sweetness.

How to Serve Easy Lemon Bars Recipe

The image shows a white marbled surface with a group of 16 square lemon bars arranged in a 4 by 4 grid. Each bar has two layers: a thick, bright yellow bottom layer with a soft, slightly shiny texture, and a thin, pale dusted top layer of powdered sugar giving a fine white coating. Several lemon wedges with bright yellow skin and juicy pale yellow flesh are placed on top of and around the bars in a casual, scattered manner. Two lemon bars are stacked, showing the distinct two layers clearly, while the others lie flat on the surface. photo taken with an iphone --ar 4:5 --v 7

Garnishes

These lemon bars shine on their own, but a delicate dusting of powdered sugar adds just the right touch of sweetness and a lovely visual appeal. For a pop of color and texture, try sprinkling finely chopped fresh mint or edible flowers. Thin lemon slices or small curls of lemon zest can also brighten their presentation if you want something extra special.

Side Dishes

Easy Lemon Bars Recipe pairs wonderfully with a light accompaniment. A scoop of vanilla bean ice cream or a dollop of whipped cream complements the tangy lemon flavor beautifully. For an elegant touch, serve alongside fresh berries—strawberries or raspberries bring an additional burst of freshness and color that balances perfectly.

Creative Ways to Present

Don’t hesitate to get creative with your plating! Cut the bars into bite-sized squares for a delightful finger food arrangement at your next party. Layer them on a pretty platter with dollops of cream and fresh mint leaves for a simple yet stunning display. You could also serve these bars in small glass jars for individual portions, adding a sprinkle of lemon zest and a sprig of thyme for a charming twist.

Make Ahead and Storage

Storing Leftovers

If you have leftovers, store your Easy Lemon Bars Recipe in an airtight container in the fridge. They will keep well for up to 4 days, maintaining their fresh flavor and satisfying texture. The chilling also helps the lemon curd stay firm without becoming watery.

Freezing

You can freeze these lemon bars for longer storage by wrapping individual slices tightly in plastic wrap and then placing them in a freezer-safe container. When stored this way, they’ll last up to 2 months. To enjoy, thaw overnight in the fridge—just note that the crust may lose some crispness after freezing.

Reheating

Since lemon bars are best served chilled, reheating is generally unnecessary. However, if you prefer them slightly softened, let them sit at room temperature for 15 to 20 minutes before serving. Avoid microwaving as it can affect the texture and dryness of the shortbread base.

FAQs

Can I use regular flour instead of rice flour?

Absolutely! While rice flour or cornstarch helps make the crust extra light and tender, you can substitute with all-purpose flour alone. Your crust might be slightly denser but will still be delicious.

How do I know when the lemon bars are done baking?

The topping should look set but still jiggle slightly in the center when gently shaken. Avoid overbaking to keep the curd creamy and smooth rather than dry or cracked.

Can I make these bars without a food processor?

Yes, definitely! Use your fingertips to rub cold butter into the dry ingredients until the mixture has a sandy texture. This may take a bit more time but works just as well.

Is it important to chill the bars after baking?

Yes, chilling is crucial because it allows the lemon curd to firm up to the right consistency, making the bars easier to cut and enhancing their flavor.

Can I adjust the sweetness or tartness of the lemon bars?

Of course! If you prefer a tarter lemon flavor, reduce the sugar slightly or add a bit more lemon juice. Conversely, for a sweeter bar, simply increase the sugar in the curd mixture a little bit.

This Easy Lemon Bars Recipe is a true crowd-pleaser that balances perfectly between tangy brightness and buttery richness.
