Easy Lemon Bar Recipe

I just made a Classic Lemon Bars Recipe that hits like sunshine in a square and won’t survive the first coffee break.

I adore this Classic Lemon Bars Recipe because it’s unapologetically bright and messy in the best way. I love that creamy, slightly tangy filling sitting on a buttery shortbread crust.

I’m obsessed with how the zest of 2 lemons and 1/2 cup fresh lemon juice hit your face with real citrus punch. These Lemon Cream Bars Recipe moments make me stop whatever I’m doing and take a bite, powdered sugar be damned.

But it’s not trying too hard. It’s loud, simple, and impossible to resist.

Give me one square and I’m done. No regrets.

I want another one right now.

Ingredients

• Butter: Basically gives that rich, tender crust you’ll happily steal straight from the pan.
• Flour (crust): The base structure, dry but necessary for that crisp, sandy bite.
• Powdered sugar (crust): Adds a soft sweetness and slight melt-in-your-mouth feel to the crust.
• Salt (crust): Just a pinch to balance sweetness and make flavors pop, not salty at all.
• Eggs: They set the lemon filling, give body and a custardy, not rubbery texture.
• Granulated sugar: Bright sweetness that lets the lemon sing without being bitter.
• Flour (filling): Thickens the filling so it’s sliceable, not runny and messy.
• Lemon juice: The star tang that wakes up every bite, fresh is best.
• Lemon zest: Basically extra punchy lemon oils, fragrant and wildly addictive.
• Pinch of salt (filling): Tames sweetness and sharpness, tiny but crucial.
• Powdered sugar (dusting): Pretty and sweet on top, optional but totally worth it.

Ingredient Quantities

• 1 cup (2 sticks) unsalted butter, softened
• 2 cups all purpose flour, divided (about 1 3/4 cups for crust, 1/4 cup for filling)
• 1/2 cup powdered sugar for the crust
• 1/4 teaspoon salt for the crust
• 4 large eggs, room temperature
• 1 1/2 cups granulated sugar
• 1/4 cup all purpose flour for the filling
• 1/2 cup fresh lemon juice (about 2 to 3 lemons), strained if you want it smooth
• zest of 2 lemons (more if you like it extra lemony)
• pinch of salt for the filling
• powdered sugar for dusting, optional

How to Make this

1. Preheat oven to 350 F and line an 8×8 inch baking pan with parchment paper leaving an overhang so you can lift the bars out later.

2. Make the crust: in a bowl cream 1 cup (2 sticks) softened unsalted butter with 1/2 cup powdered sugar until light and a bit fluffy, then stir in about 1 3/4 cups of the all purpose flour and 1/4 teaspoon salt until it comes together into a soft dough.

3. Press the crust mixture evenly into the bottom of the prepared pan using your fingers or the bottom of a measuring cup, make it fairly compact and even, then bake for 15 to 20 minutes or until the edges are just turning golden.

4. While crust bakes, whisk the filling: in a medium bowl beat 4 large room temp eggs with 1 1/2 cups granulated sugar until smooth and a little pale, then whisk in the remaining 1/4 cup all purpose flour, 1/2 cup fresh lemon juice (strained if you want it super smooth), the zest of 2 lemons and a pinch of salt.

5. When the crust is done, remove from oven and immediately pour the lemon filling over the hot crust, spreading gently so it covers evenly.

6. Return pan to oven and bake for about 20 to 25 minutes more, or until the filling is set at the edges and slightly jiggly in the center but not liquid.

7. Let the pan cool on a wire rack to room temperature, then refrigerate for at least 2 hours (overnight is even better) to make clean slices and help the filling fully set.

8. Use the parchment overhang to lift the slab out, dust the top with powdered sugar if you like, then cut into squares or bars with a sharp knife — wipe the knife between cuts for cleaner edges.

9. Serve chilled or at room temperature. Store leftover bars in an airtight container in the fridge for up to 4 days, they actually taste better after a day or two.

10. Tips and hacks: use room temperature eggs so the filling mixes smooth; strain lemon juice to avoid pulp if you want silky curd; if your filling browns too fast tent loosely with foil; for extra lemon punch add a little more zest, not more juice or the texture can get off.

8. Fine zester or microplane and a citrus juicer or reamer
9. Wire rack for cooling plus a sharp knife for clean cuts

Easy Lemon Bar Recipe Substitutions and Variations

• Unsalted butter: swap with equal parts coconut oil for a slightly tropical note, or use margarine if you need dairy free. Coconut oil will make the crust a bit more crumbly, but it’s fine.
• All purpose flour: use a 1 to 1 gluten free flour blend instead, or try almond flour (use slightly less and expect a denser, nuttier crust).
• Eggs: replace each egg with a flax egg (1 tbsp ground flax + 3 tbsp water, let sit 5 minutes) for a vegan option, or use 1/4 cup applesauce per egg though the filling will be less firm.
• Fresh lemon juice: bottled lemon juice works in a pinch, or swap for fresh lime juice for a punchier, different flavor. If using bottled, taste first its often less bright so add a little extra zest.

Pro Tips

1) Let the eggs sit out until truly room temp and whisk them well with the sugar. It helps the filling become silkier and less grainy, so don’t skip that step even if you’re in a hurry.

2) Press the crust evenly and, if you’ve got the time, pop the pan in the fridge for 15 minutes before baking. A slightly chilled crust holds its shape better and is less likely to shrink or slough away from the edges.

3) Watch the filling, not the clock. Pull the bars when the edges are set and the center still has a tiny jiggle, because carryover heat will finish it. If the top starts browning too fast, loosely tent with foil.

4) For cleaner cuts and brighter flavor, chill completely (overnight is best), dust with powdered sugar, then use a sharp knife dipped in hot water and wiped between slices. It gives you nice, neat bars and makes serving way easier.
