Lime Bars Ingredients

For the Filling

Large Eggs (Room Temperature) – Binds the filling; contributes to the custard-like texture. For vegan, consider using flax eggs.
Granulated Sugar – Sweetens the filling and balances the tartness of the lime. Substitution: Stevia or sugar substitute for lower-sugar options.
Zest of Two Limes – Enhances flavor with aromatic oils from the peel. Note: Fresh zest is recommended for best flavor.

Step‑by‑Step Instructions for Lime Bars

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This is an important step for ensuring that your Lime Bars bake evenly and develop the perfect texture. While the oven warms up, take a moment to gather all your ingredients and equipment, including a 9×13-inch baking pan and mixing utensils.

Step 2: Prepare the Crust
In a stand mixer, combine 2 cups of all-purpose flour, ½ cup of confectioners’ sugar, and ½ cup of room temperature butter. Mix on medium speed until the mixture resembles a soft dough. Once ready, press the dough evenly into the greased 9×13 pan, creating a slight edge. Bake for 20 minutes or until the crust turns golden brown.

Step 3: Make the Filling
While the crust bakes, whisk together 4 large eggs, 1 cup of granulated sugar, the zest of two limes, ½ cup of fresh lime juice, and a pinch of salt in a mixing bowl. Stir in the remaining ¼ cup of flour and ½ teaspoon of baking powder until well combined. The filling should be smooth and slightly thick.

Step 4: Combine Crust and Filling
Once the crust is golden and coming out of the oven, pour the lime filling over it immediately. Ensure the filling spreads evenly across the hot crust. This step helps the two layers bond beautifully during baking, creating the scrumptious texture of your Lime Bars.

Step 5: Bake Again
Return the pan to the oven and bake for an additional 25 minutes. Keep an eye on your Lime Bars; they should be set and slightly puffed but not jiggly in the center. A light golden hue on the edges indicates they’re just about perfect.

Step 6: Finish and Cool
After baking, sprinkle a generous dusting of confectioners’ sugar over the hot filling while it’s still warm. This not only adds sweetness but enhances the visual appeal of your finished Lime Bars. Allow them to cool in the pan at room temperature before transferring to the refrigerator for a few hours, or overnight for the best slicing results.

Step 7: Slice and Serve
Once cooled completely, cut the Lime Bars into squares using a sharp knife for clean cuts. For an elegant presentation, you can garnish with thinly sliced limes or additional powdered sugar. Serve chilled or at room temperature for a refreshing treat everyone will love!

Expert Tips for Lime Bars

Use Room Temperature Ingredients: Make sure your eggs and butter are at room temperature; this helps create a smoother filling and perfect texture in your lime bars.
Avoid Overbaking: Keep a close eye on the baking time—the filling should be set but not jiggly. Overbaking can lead to a less creamy texture.
Chill Before Slicing: For cleaner cuts, refrigerate your lime bars overnight before slicing. This makes cutting easier and gives them a firmer texture.
Fresh is Best: Always opt for fresh lime juice and zest over bottled for a vibrant flavor that truly elevates your lime bars.
Double Check Measurements: Accurate measurements are crucial—especially for the filling. A small error can affect the balance of flavors in these delightful lime bars.

Storage Tips for Lime Bars

Fridge: Store your lime bars in a tightly covered dish for up to 5 days. This helps maintain their freshness and prevents them from absorbing other odors.
Freezer: For longer storage, freeze lime bars in an airtight container or wrapped tightly in plastic wrap for up to 3 months. Thaw in the fridge before serving for the best taste and texture.
Reheating: If desired, enjoy your lime bars chilled or at room temperature. There’s no need to reheat them, as they are perfectly delicious served cold, enhancing their refreshing zing.
Cutting Tips: For cleaner slices, consider chilling the bars overnight before cutting. This step makes it easier to achieve neat squares for that perfect presentation during gatherings.

Make Ahead Options

These Lime Bars are perfect for meal prep enthusiasts! You can make the crust up to 24 hours in advance, ensuring it’s chilled and ready for the tart filling. Simply prepare the crust as directed, cool it completely, then cover and refrigerate. You can also whisk the filling ingredients together and refrigerate them for up to 3 days; just remember to give it a gentle stir before pouring it over the crust. When you’re ready to bake, combine the crust and filling, bake until set, and finish with a dusting of confectioners’ sugar while still warm. This not only saves time on busy weeknights but also ensures that your Lime Bars are just as delicious as if made fresh!

Lime Bars Recipe FAQs

How do I select ripe limes for my lime bars?
Absolutely! Look for limes that feel heavy for their size, indicating juicy fruit. The skin should be smooth, shiny, and free from dark spots. Fresh limes will also yield to gentle pressure, which means they’re ripe and ready to be zested and juiced for the perfect flavor in your lime bars!

How should I store leftover lime bars?
Very good question! Store your lime bars in a tightly covered dish in the refrigerator for up to 5 days to keep them fresh. Make sure they’re fully cooled before covering, as this helps prevent any condensation from making the crust soggy.

Can I freeze lime bars, and if so, how?
Absolutely! To freeze your lime bars, first cut them into squares after they’ve cooled completely. Then, wrap each square tightly in plastic wrap to prevent freezer burn and place them in an airtight container. They’ll keep well in the freezer for up to 3 months. When you’re ready to enjoy them, simply thaw in the refrigerator overnight for the best texture and flavor.

What should I do if the filling of my lime bars is jiggly after baking?
No worries! If your filling is still jiggly after the suggested baking time, it likely needs a few more minutes in the oven. Return them to the oven and bake in 5-minute increments until the filling is set but still slightly soft. This subtle texture is key for that creamy custard feel you want in delicious lime bars!

Are lime bars safe for people with dietary restrictions?
Great question! These lime bars can be modified to suit various dietary needs. Use gluten-free flour for a gluten-free option and vegan butter to make them dairy-free. If allergies are a concern, be sure to have clear substitutions for eggs; you can use flax eggs as a substitute for the large eggs required in the filling. Always check the labels of your ingredients to ensure they match the dietary requirements!
