Ingredients You’ll Need

For the Crust:

2 cups all-purpose flour
1/2 cup powdered sugar
1 cup unsalted butter, softened
1/2 teaspoon salt

For the Key Lime Filling:

4 large eggs
2 cups granulated sugar
2 teaspoons Key Lime zest
1/2 teaspoon baking powder
1/3 cup Key Lime juice
1/4 cup all-purpose flour

Kitchen Equipment

Before you start, make sure you have the following equipment:

9×11 baking dish
Mixing bowls (at least two large bowls)
Whisk
Pastry cutter or fork
Spatula
Measuring cups and spoons
Zester
Oven mitts

Step-by-Step Instructions

1. Preheat and Prepare the Pan

Preheat your oven to 350°F (175°C). Spray a 9×11 baking dish with non-stick cooking spray to ensure easy removal of the bars later.

2. Make the Crust

In a large bowl, combine the flour, powdered sugar, and salt. Use a pastry cutter or fork to cut in the softened butter until the mixture resembles coarse crumbs. Pour the crust mixture into the prepared baking dish and press it evenly to form the base layer. Bake the crust for 10 minutes, then remove it from the oven to cool slightly.

3. Prepare the Filling

While the crust is baking, whisk together the eggs, granulated sugar, Key Lime zest, baking powder, Key Lime juice, and flour in another large bowl. Ensure the mixture is smooth and fully incorporated.

4. Assemble and Bake

Pour the filling over the slightly cooled crust. Return the dish to the oven and bake for 25 minutes, or until the filling is set and no longer jiggles in the center.

5. Cool and Serve

Allow the bars to cool completely in the baking dish. Once cooled, sprinkle the top with powdered sugar and cut into squares. For an extra decorative touch, garnish each bar with a slice of Key Lime (optional). Enjoy!

Tips for Perfect Key Lime Bars

1. Use Fresh Key Lime Juice

For the best flavor, always use freshly squeezed Key Lime juice. Bottled juice can work in a pinch, but it often lacks the vibrant taste of fresh limes.

2. Room Temperature Ingredients

Using room temperature butter and eggs helps the ingredients blend more evenly, resulting in a smoother crust and filling.

3. Let Them Cool Completely

Patience is key! Allow the bars to cool fully before cutting them to ensure clean, even slices. If you’re short on time, you can refrigerate the dish to speed up the cooling process.

Variations and Swaps

Gluten-Free Option: Replace the all-purpose flour with a 1:1 gluten-free flour blend.
Lemon Bars: Substitute the Key Lime juice and zest with lemon juice and zest for a tangy twist.
Graham Cracker Crust: Swap the traditional crust for a graham cracker crust for added texture and flavor.
Coconut Addition: Add shredded coconut to the filling or sprinkle it on top for a tropical flair.

How to Store Key Lime Bars

Refrigeration

Store leftover Key Lime Bars in an airtight container in the refrigerator for up to 5 days. The cool temperature helps maintain their texture and flavor.

Freezing

To freeze, wrap each bar individually in plastic wrap and place them in a freezer-safe bag. They can be frozen for up to 3 months. Thaw in the refrigerator before serving.

Food and Drink Pairings

Key Lime Bars pair beautifully with:

Coffee: A hot cup of coffee or espresso balances the sweetness of the bars.
Iced Tea: Opt for unsweetened or lightly sweetened iced tea for a refreshing combo.
Vanilla Ice Cream: Serve a scoop of vanilla ice cream alongside the bars for an indulgent dessert.
Sparkling Wine: The citrus notes in the bars complement the crispness of a sparkling wine.

Frequently Asked Questions (FAQ)

Can I use regular lime juice instead of Key Lime juice?

Yes, you can use regular lime juice, but the flavor will be slightly different. Key Limes have a unique tartness that sets them apart from regular limes.

Why is my crust crumbly?

If your crust is too crumbly, it may be due to not pressing it firmly enough into the pan. Make sure to pack it down evenly to create a solid base.

How do I know when the filling is set?

The filling is set when it no longer jiggles in the center and appears slightly firm to the touch. You can also insert a toothpick; if it comes out clean, the filling is ready.

Conclusion

Key Lime Bars are a delightful dessert that’s easy to make and always impresses. With their buttery crust and tangy filling, they’re a treat for all seasons. Whether you’re serving them at a summer barbecue or enjoying them as an afternoon pick-me-up, these bars are sure to become a favorite in your recipe collection.
