Lemon Bars

Bright, tangy, and satisfyingly sweet, these Lemon Bars are a simple way to bring sunshine to any dessert table. The buttery base bakes into a slightly golden, tender foundation that contrasts with a smooth, custard-like lemon topping. The glaze adds an extra punch of fresh citrus and a glossy finish that settles into a delicate crackle. Expect a pleasing balance of sweet and tart, a melt-in-your-mouth texture from the butter and eggs, and an aromatic lift from freshly grated lemon zest. These bars are ideal for afternoon tea, potlucks, picnic desserts, or anytime you want a bright finish to a meal. They travel well, slice neatly after chilling, and are quick enough for a last-minute treat. Make them when you want a nostalgic, crowd-pleasing dessert that showcases pure lemon flavor without fuss.

Ingredients

• 1/2 cup unsalted butter, softened
  Helpful note: Soft butter creams easily with the sugar and flour to form the base texture.

• 3/4 cup all-purpose flour
  Helpful note: Provides structure for the base. Measure by spooning into the cup and leveling.

• 2 large eggs, room temperature
  Helpful note: Room temperature eggs incorporate more smoothly, for a silky lemon layer.

• 2 tablespoons lemon zest (from about 2 lemons), finely grated
  Helpful note: Zest adds concentrated lemon aroma and bright citrus oils. Use a fine grater.

• 2 tablespoons fresh lemon juice
  Helpful note: Fresh juice gives a clean, tart flavor not matched by bottled juice.

• 3/4 cup granulated sugar
  Helpful note: Sweetens the batter and helps create a tender crumb for the base.

• 1/4 teaspoon sea salt
  Helpful note: Enhances the flavors and balances the sweetness.

• 4 tablespoons fresh lemon juice (for glaze)
  Helpful note: Adds tang to the glaze for a shiny, citrusy finish.

• 8 teaspoons lemon zest (for glaze), finely grated
  Helpful note: Extra zest in the glaze boosts aroma and visual appeal.

• 1 cup icing sugar (powdered sugar), sifted
  Helpful note: Sifting prevents lumps in the glaze for a smooth spread.

Step-by-step Instructions

1. Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking dish with butter and set it aside. Make sure the butter reaches into the corners to prevent sticking.

2. In a stand mixer or using a hand mixer, beat the softened butter, granulated sugar, all-purpose flour, and sea salt until just combined and slightly crumbly. The mixture should hold together when pressed.

3. In a separate bowl, whisk together the eggs, 2 tablespoons of lemon zest, and 2 tablespoons of fresh lemon juice until smooth. This creates the lemon custard base for the bars.

4. Gradually add the egg-lemon mixture to the flour mixture and beat on low until smooth. Scrape down the bowl as needed to ensure everything is fully incorporated.

5. Pour the batter into the prepared baking dish and smooth the top with a spatula so the layer is even. For an even bake, tap the pan lightly on the counter to level it.

6. Bake for 23 to 25 minutes, or until the edges are golden brown. The center should be set but may still have a slight jiggle.

7. Allow the bars to cool completely in the pan. Cooling fully helps the lemon layer set so the bars slice cleanly.

8. For the glaze, whisk together 1 cup of sifted icing sugar, 4 tablespoons of fresh lemon juice, and 8 teaspoons of lemon zest until smooth. Taste and adjust by whisking a little longer if needed to dissolve any lumps.

9. Once the bars are cool, spread the glaze over the top and let it set for at least 20 minutes before slicing into squares. Use a sharp knife wiped clean between cuts for neat slices.

Frequently Asked Questions

Q: Can I use bottled lemon juice instead of fresh?
A: Fresh lemon juice is best for bright flavor, but bottled juice will work in a pinch.

Q: How do I know when the bars are fully baked?
A: The edges should be golden brown and the center mostly set with a slight jiggle.

Q: Can I make these in a different size pan?
A: You can, but baking time may change. An 8×8-inch pan gives the intended thickness and bake time.

Q: Why should I let the bars cool completely before glazing?
A: Cooling lets the lemon layer set so the glaze spreads smoothly and slices cleanly.

Q: How should I slice the bars for clean edges?
A: Use a sharp knife and wipe it clean between cuts. Chilling briefly can also help.

Q: Are these bars suitable for make-ahead dessert needs?
A: Yes, they keep well refrigerated and can be made a day in advance.

People Also Ask

Q: What gives lemon bars their tart flavor?
A: Fresh lemon juice and lemon zest provide the bright tartness in both the filling and glaze.

Q: Can I prepare the batter in a bowl by hand?
A: Yes, you can mix by hand, but a mixer speeds up blending and gives a more even texture.

Q: Is it better to sift icing sugar for the glaze?
A: Sifting prevents lumps and creates a smoother glaze that spreads evenly.

Q: How thick should the lemon layer be?
A: The lemon layer should be thick enough to be custardy and set, as in this 8×8-inch pan recipe.

Q: Will the bars keep their texture after refrigeration?
A: Refrigeration firms the lemon layer and preserves texture for several days.

Q: Can I double this recipe for a larger crowd?
A: Doubling the ingredients and using a larger pan works, but watch baking time and test for doneness.

Q: What causes a grainy glaze?
A: Undissolved powdered sugar can make a glaze grainy. Sift and whisk thoroughly.

Q: How can I make cleaner slices?
A: Chill the bars briefly and clean the knife between each cut for neat squares.
