What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and if you don’t have fresh lemons, bottled lemon juice works in a pinch (though fresh is always best!).

For the Buttery Shortbread Crust:

• All-purpose flour: 1 ¾ cups (220g) – I prefer King Arthur for consistent texture
• Granulated sugar: ⅓ cup (65g) – adds just the right touch of sweetness
• Salt: ¼ teaspoon – balances flavors
• Unsalted butter: ¾ cup (170g), softened – makes the crust tender and rich (use European butter if you want extra creaminess)
• Vanilla extract: 1 teaspoon – adds subtle warmth

For the Tangy Lemon Filling:

• Large eggs: 4, room temperature – helps set the custard
• Granulated sugar: 1 ½ cups (300g) – balances the tartness
• Fresh lemon juice: ⅔ cup (160ml), strained – freshly squeezed is best for zingy brightness
• Lemon zest: 2 tablespoons – for an aromatic boost
• All-purpose flour: ¼ cup (30g) – thickens the filling
• Salt: a pinch – enhances flavor depth

Substitution tips: For a gluten-free crust, swap the all-purpose flour with a gluten-free flour blend (make sure it contains xanthan gum). If dairy is a concern, use a vegan butter alternative suitable for baking. You can swap granulated sugar with coconut sugar for a hint of caramel flavor, but the color will darken slightly.

Equipment Needed

• 9×13-inch baking pan: Preferably metal for even heat distribution, but glass works too.
• Mixing bowls: One large and one medium-sized for crust and filling respectively.
• Electric mixer or hand whisk: To cream butter and sugar, and beat the filling smoothly.
• Microplane or fine grater: For zesting lemons finely without the bitter pith.
• Citrus juicer: Handy but optional; you can squeeze lemons by hand.
• Rubber spatula and wooden spoon: For mixing and folding ingredients.
• Cooling rack: Essential for cooling bars evenly to avoid soggy bottoms.

If you don’t have an electric mixer, no worries—this recipe works well with a sturdy whisk and some elbow grease. A non-stick baking pan makes cleanup simpler, but lining your pan with parchment paper also helps. I’ve found that using a metal pan gives the crust a lovely golden edge, but if glass is what you’ve got, just watch baking times closely.

Preparation Method

1. Preheat your oven to 350°F (175°C). Grease your 9×13-inch pan lightly or line it with parchment paper, leaving an overhang for easy removal later. This step is crucial to prevent sticking and make your life easier when cutting bars.
2. Prepare the shortbread crust: In a large bowl, whisk together 1 ¾ cups (220g) flour, ⅓ cup (65g) sugar, and ¼ teaspoon salt. Add the softened ¾ cup (170g) butter and 1 teaspoon vanilla extract. Using an electric mixer or your fingers, mix until the dough comes together and looks crumbly but holds when pressed.
3. Press the dough evenly into the bottom of your prepared pan. Use the bottom of a measuring cup or your fingers to create a smooth, compact surface. This helps the crust bake evenly.
4. Bake the crust for 15-20 minutes, or until the edges are lightly golden. Keep an eye on it—overbaking may dry it out, but underbaking results in a soggy base.
5. While the crust bakes, prepare the lemon filling: In a medium bowl, whisk 4 large eggs and 1 ½ cups (300g) sugar together until smooth and slightly frothy. Add ⅔ cup (160ml) fresh lemon juice and 2 tablespoons lemon zest. Stir in ¼ cup (30g) flour and a pinch of salt until fully combined with no lumps.
6. Pour the filling over the warm crust right out of the oven. The crust’s warmth helps the filling set beautifully.
7. Bake for an additional 20-25 minutes, or until the filling is just set but still slightly jiggly in the center. The residual heat will finish the job as it cools.
8. Cool completely on a wire rack, then chill in the fridge for at least 1 hour before slicing. This chilling step is key to getting clean, neat squares.
9. Cut into 16 bars and dust with powdered sugar if you like. Use a sharp knife, wiping it clean between cuts for perfect edges.

Pro tip: If your filling bubbles too much while baking, place a baking sheet on the rack below to catch drips and make cleanup easier. When zesting lemons, avoid the white pith—it can turn your bars bitter. Also, letting the bars rest overnight in the fridge intensifies the lemon flavor and firms up the texture beautifully.

Cooking Tips & Techniques

To get those tangy lemon bars just right, here are some tricks I’ve picked up along the way. First off, don’t skip softening your butter properly; it’s the secret to that tender, flaky shortbread crust. I’ve learned the hard way that cold butter doesn’t mix well and results in a crumbly mess.

When mixing your crust, handle the dough gently—overworking it can develop gluten, making the crust tough. For the filling, whisk the eggs and sugar well to incorporate air, which helps the custard set with a light texture rather than dense or rubbery.

Timing is everything here: bake the crust until just golden, then immediately pour in the filling while it’s still hot. This step helps the layers meld perfectly without sogginess. Watch the lemon filling closely during baking—the center should jiggle slightly, like a good cheesecake, when done.

Multitasking tip: prepare your filling while the crust bakes to streamline the process. If you want a shinier finish, I sometimes brush the crust with a little melted butter before baking. And if your bars crack during baking, don’t fret—powdered sugar dusting hides imperfections nicely!

Variations & Adaptations

These lemon bars are easy to tweak depending on what you’ve got on hand or your dietary needs. Here are some of my favorite variations:

• Gluten-Free: Swap the all-purpose flour in the crust and filling with a gluten-free blend like Bob’s Red Mill 1-to-1. Just watch the baking time as gluten-free flours sometimes brown faster.
• Lower Sugar: Reduce the sugar in the filling by up to ⅓ cup or use a natural sweetener like honey or maple syrup. The bars will be more tart but still delicious.
• Berry Twist: Swirl in ½ cup of fresh or frozen raspberries or blueberries into the lemon filling before baking for a fruity surprise. It adds color and a lovely flavor contrast.
• Dairy-Free: Use coconut oil or a vegan butter substitute in the crust and swap eggs for a flaxseed “egg” (1 tablespoon flaxseed meal + 3 tablespoons water per egg), though the texture will be a bit different.
• Herb-Infused: Add a teaspoon of finely chopped fresh thyme or basil to the crust for a sophisticated flavor burst that pairs surprisingly well with lemon.

Personally, I like the berry variation for summer picnics—it’s refreshing and pretty on a serving platter. Just press the berries gently into the filling before baking to avoid sinking. If you try the herb twist, start with a small amount and adjust to taste!

Serving & Storage Suggestions

Serve these tangy lemon bars chilled or at room temperature for the best texture. Dusting with powdered sugar right before serving adds a lovely touch of sweetness and a pretty finish. They pair beautifully with a hot cup of tea or a crisp glass of sparkling water if you want to keep things light.

If you’re serving at a party, arrange the bars on a decorative tray with a few fresh lemon slices or edible flowers for that Pinterest-worthy look. They also make fantastic gifts—wrap them in parchment paper tied with twine for a homemade touch.

Store leftover lemon bars in an airtight container in the refrigerator for up to 4 days. They keep well and the flavors actually deepen over time. You can freeze them too—wrap squares individually in plastic wrap and freeze for up to 3 months. Thaw overnight in the fridge before serving.

For reheating, a quick 10-second zap in the microwave softens the bars without melting the filling too much. But honestly, these bars are perfect cold, especially on warm days when the tartness feels extra refreshing.

Nutritional Information & Benefits

One serving (1 bar) of these lemon bars contains approximately 220 calories, 10g fat, 30g carbohydrates, and 3g protein. They offer a modest dose of vitamin C from fresh lemon juice and zest, which supports the immune system and adds antioxidant benefits.
