The Best Lemon Bar Recipe

Bylilan Sage April 20, 2026April 20, 2026

Introduction

These lemon bars are the perfect balance of tangy and sweet with a buttery crust and a bright lemon filling. They’re easy to make and a refreshing treat for any occasion. You’ll love their classic, zesty flavor and tender texture.

A stack of three lemon bars is shown, each bar having two layers: a bottom light beige crumbly crust and a top bright yellow, smooth, and slightly glossy lemon filling. A thin dusting of white powdered sugar is sprinkled on top of each bar and visible between the layers, adding a soft texture. The bars are placed on a surface with a white marbled texture, and some powdered sugar is scattered around them. In the background, blurred yellow lemon slices can be seen. photo taken with an iphone --ar 4:5 --v 7

Ingredients

1/2 cup unsalted butter (softened)
1/4 cup powdered sugar
1 cup all-purpose flour
Pinch salt
3 large eggs
1 cup granulated sugar
2 tablespoons granulated sugar
1/2 cup fresh lemon juice
1 tablespoon lemon zest
1/4 cup all-purpose flour (sifted)
Powdered sugar (for dusting)

Instructions

Step 1: Preheat your oven to 350°F and line an 8×8 inch baking pan with parchment paper, leaving an overhang for easy removal.
Step 2: In a medium bowl, cream together the softened butter and powdered sugar until light and fluffy. Add 1 cup flour and a pinch of salt, mixing until just combined.
Step 3: Press the dough evenly into the bottom of the prepared pan. Bake the crust for 13–14 minutes, or until the edges are slightly golden brown. Remove from the oven.
Step 4: While the crust bakes, whisk together the eggs, 1 cup granulated sugar, lemon juice, lemon zest, and sifted 1/4 cup flour in another bowl until smooth and well combined.
Step 5: Pour the lemon filling over the warm crust, spreading it evenly. Return the pan to the oven and bake for 20–22 minutes, until the filling is set and the edges turn light golden.
Step 6: Remove from the oven and let the bars cool completely in the pan. Once cooled, dust with powdered sugar, lift out using the parchment overhang, slice into squares, and enjoy.

Tips & Variations

Use fresh lemons for the brightest flavor; bottled lemon juice won’t give the same fresh tang.
For a more vibrant lemon flavor, add an extra teaspoon of zest to the filling.
Chill the bars in the refrigerator for at least an hour before slicing to get clean edges.
Try sprinkling a little extra powdered sugar on top just before serving for a pretty finish.

Storage

Store lemon bars in an airtight container in the refrigerator for up to 4 days. Let them come to room temperature or warm briefly before serving for the best texture. They can also be frozen for up to 1 month; thaw in the fridge overnight before enjoying.

How to Serve

The image shows square lemon bars stacked on each other, each having two clear layers: a thick bright yellow lemon layer on top and a thinner light beige crust at the bottom. The top surface of the lemon bars is dusted with white powdered sugar that contrasts with the lemon's yellow. The bars have clean, sharp edges, and the texture of the crust looks crumbly while the lemon layer appears smooth and slightly glossy. The background is a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make lemon bars ahead of time?

Yes, lemon bars keep well in the refrigerator for several days and can be made a day ahead. Just store them in an airtight container and dust with powdered sugar before serving.

How do I know when the lemon filling is done?

The filling should be set and slightly firm to the touch, with lightly golden edges. It’s okay if the center jiggles a little when you gently shake the pan, as it will continue to set while cooling.
