There’s something quietly magical about the scent of citrus wafting through a kitchen. It always reminds me of summers at my grandmother’s house—bare feet on cool tile floors, the hum of a ceiling fan overhead, and a tray of lime bars chilling in the fridge. These bright and tangy lime bars aren’t just a dessert. They’re a piece of family tradition, a refreshing escape from the summer heat, and a beloved recipe that bridges generations.

Unlike their lemon cousins, lime bars bring a bold tartness that surprises the taste buds in the best way. Their vibrant flavor and rich color make them an eye-catching addition to any dessert spread. These bars were a staple at family picnics, tucked neatly into wax paper and passed around between bites of grilled corn and potato salad. Now, I bake them every spring and summer, just when limes are at their peak and the days beg for something cool and sweet.

Whether you’re hosting a garden brunch, prepping for a potluck, or simply need a bite of sunshine in your day, these lime bars are just the thing.

• ¼ teaspoon salt
• ½ cup (1 stick) butter, cold and cut into chunks

For the Lime Filling:

• 1¼ cups granulated sugar

How to Make Lime Bars

Making lime bars at home is surprisingly simple, and the results are deliciously rewarding. Here’s how to bake them just like my grandmother used to—with a few modern shortcuts for ease.

STEP-BY-STEP INSTRUCTIONS:

1. Prep Your Pan and Oven

Start by preheating your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper, leaving an overhang on the sides. This makes removing the bars super easy later on.

2. Make the Shortbread Crust

In a food processor, combine the flour, powdered sugar, salt, and butter. Pulse until the mixture resembles coarse crumbs. If you don’t have a food processor, use a pastry cutter or your hands to blend the butter in.

Pour the crust mixture into your prepared pan and press it down evenly. Bake for 18–20 minutes, or until lightly golden.

3. Prepare the Lime Filling

While the crust is baking, whisk together the granulated sugar and flour in a large bowl. Add the eggs one at a time, whisking well after each. Then stir in the lime zest, lime juice, and a touch of food coloring if you’d like that vibrant green hue.

4. Bake the Bars

Once the crust comes out of the oven, immediately pour the lime filling on top. Return the pan to the oven and bake for 18–20 minutes, or until the center is set and no longer jiggles.

5. Cool and Chill

Let the bars cool at room temperature for about an hour, then refrigerate for 1–2 hours until firm. Once chilled, lift the bars from the pan using the parchment overhang and cut into neat squares.

Helpful Tips:

• Use Fresh Limes: Bottled juice just doesn’t capture the same bright, fresh flavor.
• Avoid the White Pith: When zesting, stick to the green outer peel to avoid bitterness.
• Chill Thoroughly: These bars slice much better when cold, so don’t skip that chilling step.
• Add a Dusting: A sprinkle of powdered sugar right before serving adds a pretty finish.
