Step‑by‑Step Instructions for Lime Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, prepare an 11×7-inch baking dish by lining it with parchment paper, ensuring enough overhang for easy removal later. This step is crucial, as you want your Lime Bars to bake evenly and release cleanly.
Step 2: Make the Shortbread Crust
In a food processor, blend together the all-purpose flour, powdered sugar, and salt. Add the cold butter, cutting it into small pieces to facilitate mixing. Pulse the mixture until it resembles coarse crumbs. Firmly press this crumbly mixture into the bottom of the prepared baking dish, smoothing the surface. Bake for 18-20 minutes until golden brown around the edges.
Step 3: Prepare the Lime Filling
While the crust bakes, whisk together the granulated sugar and flour in a medium bowl. Gradually add the large eggs, beating well after each addition to create a smooth base. Then, stir in the lime zest and fresh lime juice, along with food coloring if desired, blending until the mixture is velvety and all ingredients are well incorporated.
Step 4: Bake the Filling
Once the crust is ready, remove it from the oven and pour the lime filling over the hot crust. Use a spatula to spread it evenly. Return the dish to the oven and bake for an additional 18-20 minutes. You’ll know your Lime Bars are done when the center is set and no longer jiggles when gently shaken.
Step 5: Cool and Chill
Allow the Lime Bars to cool completely in the pan for about 1 hour at room temperature. After they have cooled, cover the dish and place it in the refrigerator for 1-2 hours to chill. This chilling step helps the flavors develop and allows for clean slicing into squares.
Step 6: Slice and Serve
Once chilled, carefully lift the Lime Bars out of the pan using the parchment paper overhang. Place them on a cutting board and slice into squares. Dust with powdered sugar if desired, and serve chilled for a refreshing treat that highlights the bright flavor of lime at every bite.

Expert Tips for Lime Bars
-
Egg Temperature Matters: Ensure your eggs are at room temperature for smoother incorporation into the filling, leading to a creamier texture.

-
Cooling is Key: Let your Lime Bars cool completely before chilling. This helps set the filling properly and makes slicing easier.
-
Flavorful Variations: Experiment by swapping lime juice with lemon or grapefruit for different flavor profiles in your Lime Bars.

Lime Bars Recipe FAQs
What type of limes should I use for the best flavor?
Absolutely! For the best flavor, always opt for fresh, ripe limes. Look for limes that are slightly soft when gently squeezed and have a vibrant green color. Avoid any that are hard or have dark spots, as these may be overripe and lack the juicy zest needed for perfect Lime Bars.
How long can I store Lime Bars in the refrigerator?
Very! You can store your Lime Bars in an airtight container in the refrigerator for up to 7 days. This is essential to keep them fresh, ensuring that the creamy texture and tangy flavor remain delightful. Just be sure to allow them to cool completely before refrigerating to prevent condensation.
Can I freeze Lime Bars?
Absolutely! To freeze Lime Bars, first, let them cool completely. Then, wrap each bar individually in plastic wrap, ensuring they’re tightly sealed. Afterward, place them in a freezer-safe container or a zip-lock bag to prevent freezer burn. They can be stored for up to 3 months. When you’re ready to enjoy them, transfer them to the refrigerator for several hours to thaw gently and maintain their texture.
What should I do if my filling is too jiggly after baking?
If your filling is still jiggly after the recommended baking time, don’t fret! Simply return the Lime Bars to the oven and bake for an additional 5-minute increments, checking closely. You want to achieve a firm set where the bars wobble slightly but don’t jiggle freely. This jiggle test is key to ensuring perfectly smooth and creamy Lime Bars!
Can I use other citrus fruits in this recipe?
Very! You can absolutely unleash your creativity with other citrus fruits. Substitute fresh lime juice with lemon or grapefruit juice for distinct flavor profiles. If using other citrus zest, like orange, just ensure to adjust the sugar slightly to balance the sweetness. The more the merrier when it comes to flavor combinations!
Are Lime Bars suitable for people with egg allergies?
While traditional Lime Bars require eggs for structure, you can create a delicious egg-free version using egg replacements like flaxseed meal or commercial egg substitutes. Mix 1 tablespoon of flaxseed meal with 2.5 tablespoons of water for each egg, letting it sit until it thickens. This will help keep the texture intact and allow everyone to enjoy these zesty treats!
