Ingredient Notes

5 ingredient lemon bar ingredients on table

Sugar: Adds sweetness to balance the tartness of the lemon, and contributes to the texture of the crust and filling. For the crust, light brown sugar can be used for a deeper flavor. In the lemon layer, honey or maple syrup can replace sugar, though it will slightly alter the flavor profile.
Butter: Provides richness, flavor, and structure to the shortbread crust. Use salted butter for best taste. Unsalted butter with a pinch of salt, or a plant-based butter for a dairy-free version can be used as well.
All-Purpose Flour: Gives structure to the crust and helps thicken the lemon filling. Gluten-free all-purpose flour blends can be used for a gluten-free version, though textures may vary slightly.
Eggs: Use large Grade AA eggs. Eggs are crucial for setting the lemon filling, adding richness, and creating a smooth texture so don’t skip these.
Lemon Juice: Provides the signature tart flavor and acidity to the bars. For best results, use freshly squeezed lemon juice. Store-bought lemon juice can be used in a pinch.

Types of Lemons

Any variety of lemon, including Meyer lemons, can be used for lemon bars. Meyer lemons are a cross between lemons and mandarin oranges, offering a sweeter taste and a more orange hue in the juice.

Baking to Perfection

While we give you ideal baking time, lemon bars are done when the center is fully set and doesn’t jiggle. Lightly touching the center shouldn’t leave an imprint.

Topping Ideas

Tired of the same old same old when it comes to powdered sugar-dusted lemon bars? Switch things up with one of these topping ideas:

Berry Topping: Pair the lemon bars with fresh berries like raspberries, blueberries, or sliced strawberries for a refreshing contrast and a visually appealing garnish.

Candied Lemon: Top your bars with candied lemon slices for a stunning and delicious garnish. They add a sweet, citrusy zing and look beautiful.f

Cream Cheese Frosting: Spread a thin layer of cream cheese frosting on top for a rich, creamy contrast to the tangy lemon.

Coconut Flakes: Toasted coconut flakes can add a tropical twist and a delightful crunch.

Nuts: Sprinkle chopped almonds, pistachios, or walnuts on top for added texture and a nutty flavor.

Meringue Topping: For a lemon meringue pie twist, top your bars with a layer of fluffy meringue and lightly torch it for a golden finish.

Storage and Reheating Instructions

Refrigerate leftovers in an airtight container for up to 5 days.

Freeze by wrapping individual portions in plastic wrap and store in a freezer-safe bag. They can be stored in the freezer for up to 3 months.

Thaw portions in the refrigerator for several hours or overnight. This gradual thawing helps maintain their texture and ensures they taste just as good as when they were first made.
