There’s something undeniably refreshing about citrus desserts, and lime—often the underdog of the citrus world—deserves its moment to shine. These Bright and Tangy Lime Bars bring the perfect punch of citrus zing wrapped in a buttery shortbread crust. Whether you need a pick-me-up treat, a picnic dessert, or something vibrant for a spring or summer gathering, these bars are the sweet-tart solution.

Why You’ll Fall in Love with These Lime Bars

Lime bars are often overlooked in favor of their cousin, lemon bars—but let us tell you, lime brings a whole new level of brightness and depth. These bars are intensely flavorful without being overly sweet. The lime curd filling is creamy and custardy, and it pairs beautifully with the rich, melt-in-your-mouth shortbread base. They’re simple to make but taste like you picked them up from an artisan bakery.

This recipe leans into natural ingredients—real lime juice and zest—no bottled stuff here. The fresh flavor is so vivid and tangy, it practically dances on your tongue.

The Inspiration Behind the Recipe

Lime desserts bring a sense of vibrancy that feels like a burst of sunshine. We wanted to create a dessert that’s equal parts bright, tangy, and comforting. Think Key Lime Pie, but in a hand-held, snackable format that’s easier to prep and serve. These lime bars are ideal for everything from casual get-togethers to elegant brunch spreads.

Ingredients Snapshot

Here’s what goes into each layer:

1. Shortbread Crust: Just four ingredients—butter, flour, sugar, and a pinch of salt. It’s pressed into a baking dish and pre-baked until golden.

2. Lime Filling: Freshly squeezed lime juice, lime zest, eggs, sugar, and a touch of flour to thicken. Whisked together and poured over the warm crust.

3. Topping: A light dusting of powdered sugar to finish. Optional garnish: lime zest or candied lime slices for visual flair.

Tips for the Best Lime Bars

Use fresh limes. Bottled juice can’t match the flavor of fresh citrus.

Zest before juicing. It’s much easier to zest whole limes than squeezed halves.

Let them chill. These bars firm up in the fridge and taste even better cold.

Dust right before serving. Powdered sugar can absorb moisture and disappear over time.

Flavor Variations

Feeling adventurous? Add a little coconut to the crust or filling for a tropical twist. You can also mix lime with lemon or orange juice for a citrus medley bar. Want extra tang? Add a touch of Greek yogurt to the filling for a creamy boost.

Perfect For:

Summer potlucks

How to Store

Store your lime bars in an airtight container in the fridge for up to 5 days. They can also be frozen—just wrap them tightly and thaw in the fridge overnight before serving.
