This is my favorite lemon bar recipe! They’re made with a 3-ingredient buttery shortbread crust, and the lemon custard is sweet, tart, and gooey! This has been our family recipe for over 30 years, and it’s the best lemon bar recipe.

The process of making lemon bars is straightforward. It begins with a simple, three-ingredient crust that provides a buttery shortbread texture for the gooey lemon custard to sit atop.

The tart lemon filling is made in one bowl and whisked together. I garnish them with a dusting of powdered sugar, which complements the bars’ gooey texture with a hint of sweetness.

Shopping List and Ingredient Notes

Butter: Use unsalted butter for the crust to control the salt level. The butter needs to be softened to create a tender shortbread base.

Flour: All-purpose flour works best for a sturdy crust and to thicken the filling.

Sugar: Powdered sugar is ideal for a smooth crust. For the filling, granulated sugar is perfect for achieving a glossy, sweet-tart lemon topping.

Confectioners Sugar: This is used to sweeten the shortbread crust.

Baking Powder: This acts as a leavening agent for the bars.

Eggs: They are essential for the structure and richness of the lemon filling. I prefer large or extra-large eggs for consistency.

Fresh Lemon Juice: Freshly squeezed lemon juice and freshly grated zest are non-negotiable for the filling. They provide the bright, zesty flavor characteristic of lemon bars.

Recipe Tips and Variations

How to Remove: Bars can be challenging to remove. Ensure they are cooled completely, then go around the edge with a knife to loosen the crust from the sides of the pan before cutting it into squares. Remember, the first square is the hardest to take out! 

Gooey Goodness: These are supposed to be gooey and a little messy. They taste better that way, so don’t be alarmed if the filling is gooey.

Lemon Freshness: The brightness and tang of the lemon flavor are crucial, so I always use fresh lemons, and when my Meyer lemons are in season, I go with those first. 

Pan Size: Use an 8×8 or 9×9 pan to make these bars. A metal pan works best, but a glass pan will also work. Just keep in mind that the baking time may vary slightly.

Gluten-Free Option: For a gluten-free version of these lemon bars, use 1:1 gluten-free flour instead of all-purpose flour for the crust. The results are equally delicious!

Other Citrus Fruits: While lemon bars are a classic, you can easily experiment with other citrus fruits like limes or make orange bars using orange juice for a unique twist on this recipe. 

Allow to Cool: Allow the bars to cool completely before slicing, as this helps them to set and makes them easier to cut. This could mean letting them sit for up to 1 hour.

Storing and Freezing Lemon Bars

While these lemon bars rarely last long in my household, they can be stored in an airtight container in the fridge for up to 5 days.

For more extended storage, I recommend freezing them. Wrap them tightly in plastic wrap and place them in an airtight container before storing them in the freezer for up to 3 months.

Do Lemon Bars Need to Be Refrigerated?

To maintain their stability and freshness, I always refrigerate lemon bars if not consumed on the same day. Wrap them gently in plastic wrap and keep them in the fridge.

Can Lemon Bars Sit out Overnight?

I don’t recommend leaving lemon bars out overnight due to the risk of bacteria growth from the egg content. It’s best to store them in the refrigerator.

How Long Can You Keep Lemon Bars?

In the fridge, lemon bars stay suitable for a few days. For long-term storage, freeze them for up to four months — a convenient option for having desserts ready.

Can I Freeze Lemon Bars?

Absolutely, freezing is a great option. Wrap them individually in wax paper, again in plastic wrap, then into a freezer bag or airtight container, keeping them towards the back of your freezer.

How Do You Cut Lemon Bars Cleanly?

For clean cuts, allow the bars to cool completely. A hot, wet, sharp knife slices them neatly, preserving their alluring appearance.

Can I use bottled lemon juice instead of fresh lemons in a lemon bar recipe?

I do not recommend bottled lemon juice as it won’t be the same. The fresh lemons provide the best tangy flavor and ideal sweetness that bottled lemon juice doesn’t.
