Lemon Bars are the kind of dessert that always disappears first at any gathering. These bars are buttery and perfectly sweet with that tangy lemon bite. They have a simple shortbread crust and a silky lemon layer on top, finished with a snowy dusting of powdered sugar.
What makes these lemon bars so good is the texture combo, tender crust with a smooth, citrusy filling that slices into pretty squares every time. They are ideal for spring parties, potlucks, baby showers, or whenever you need an easy dessert that feels bakery-style.

Why we think you’ll love it:
- Fresh fruit flavor. We love the bright lemon flavor! It’s refreshing and delicious.
- 10 minutes of prep. The shortbread crust is simple, and the filling is a breeze making this one of our best-loved easy desserts!
- Freezable! These can be enjoyed at room temperature or chilled. They can even be frozen for longer storage – perfect for making ahead of time.
Lemon Bars Ingredients
- Unsalted butter, room temperature (1 cup): This creates that rich, tender shortbread crust and helps everything press smoothly into the pan.
- All-purpose flour (2 cups): Gives the crust structure so it bakes up sturdy enough to hold the lemon layer.
- Powdered sugar (½ cup): Sweetens the crust while keeping it soft and delicate, not gritty.
- Salt (½ teaspoon): Balances the sweetness and makes the buttery crust taste more flavorful.
- Eggs (4): Set the lemon layer so it becomes custardy and sliceable instead of runny. Room temperature eggs incorporate better than cold eggs.
- Lemon juice (5-6 tablespoons): Brings the tangy lemon flavor that makes lemon bars so refreshing. For fresh lemon juice you’ll need 2 medium-sized lemons, or you can use bottled lemon juice.
- Granulated sugar (1¾ cups): Sweetens the filling and balances the tart lemon so it tastes bright, not puckery.
- All-purpose flour (⅓ cup): Thickens the lemon layer so it bakes up smooth and holds its shape when cut.
- Powdered sugar, for topping (powdered sugar, for topping): Adds that classic lemon bar finish and a little extra sweetness on top. You can also use a lemon glaze or a layer of lemon frosting.
How to Make Lemon Bars
PREP. Preheat the oven to 375°F. Grease a 9×13-inch glass baking dish and set aside.
CRUST. In a medium bowl, mix butter, flour, powdered sugar, and salt with a pastry cutter or spatula. Press the crust firmly and evenly into the pan so it bakes into a solid base and does not crumble when cutting.
- Bake for 20 minutes. Make sure to not let it brown.
LEMON LAYER. While the crust is baking, blend eggs, lemon juice, granulated sugar, and flour in a medium bowl with a hand mixer until frothy, about 30 seconds. Pour the lemon mixture over a warm crust, this helps it bond and bake evenly.
- Bake for an additional 22–24 minutes. Bars are done when the edges begin to turn golden brown and the middle is set and does not wobble.
SERVE. Let cool completely in the pan. Sift powdered sugar over the top before cutting into lemon bars.
Kristyn’s Lemon Bars Tips
- We prefer fresh-squeezed lemon juice, and sometimes we include 1-2 teaspoons lemon zest for extra lemon flavor.
- If you overcook your lemon bars, they will curdle, look eggy, and end up with more of a grainy texture. Make sure to take them out of the oven as soon as the middle is set.
- Don’t worry if air bubbles appear. They are common and get covered with the powdered sugar topping.
- We often garnish each lemon square with a sliver of fresh lemon or add fresh berries (raspberry, blueberry, strawberry) to each square.
- For clean, even slices, we like to bake our bars in a parchment paper-lined pan. Once baked and cooled, lift out completely. Dip a chef’s knife in hot water, wipe off the water, and then slice.
