Ingredients for Key Lime Bars Citrus Treat
When it comes to creating my Key Lime Bars Citrus Treat, simplicity is key. Here’s what you’ll need:

- Granulated sugar: Sweetens the crust and custard, balancing the tanginess.
- All-purpose flour: The base for both the crust and the custard, providing stability.
- Kosher salt: Just a pinch to enhance all the flavors.

How to Make Key Lime Bars Citrus Treat
Making my Key Lime Bars Citrus Treat is easier than you might think! Just follow these steps, and you’ll have a tasty dessert in no time.
Step 1: Prepare Your Pan
First thing’s first: preheat your oven to 350°F (175°C).
Then, grab a 9×13 inch baking pan. Line it with parchment paper, leaving some overhang on the sides. This will help you lift the bars out later.
Next, grease the paper really well with a little butter or cooking spray. This will give you a nice, clean cut when it’s time to slice your bars.
Step 2: Create the Shortbread Crust
In a large bowl, cream 1 cup of softened unsalted butter. I usually mix it for about 2–3 minutes until it gets light and fluffy.
Now, add in 1/2 cup of granulated sugar along with the 2 cups of all-purpose flour and 1/4 teaspoon of kosher salt.
Mix until combined. It should resemble a crumbly dough. Don’t worry if it seems a bit dry!
Now, press this mixture evenly into your prepared pan using your fingers. This part is fun—just imagine you’re smoothing out a sandy beach!
Step 3: Chill and Bake the Crust
Once your crust is pressed in, chill it in the fridge for about 15 minutes. This helps it hold its shape while baking.
After chilling, bake it in the preheated oven for 15-20 minutes. You want it to be lightly golden on top.
Use a toothpick to check the doneness. If it comes out clean, it’s good to go. Take it out and let it cool completely on a wire rack.
Step 4: Make the Key Lime Custard
While the crust is cooling, let’s whip up that zesty custard! In a large bowl, whisk together 5 large eggs, 1 cup of granulated sugar, 1/4 cup of all-purpose flour, 3/4 cup of freshly squeezed key lime juice, and 2 tablespoons of grated key lime zest.
Make sure to mix until everything is smooth and well combined. This custard is where that magic flavor comes from!
Step 5: Bake the Custard Filling
Pour that luscious custard filling over your cooled shortbread crust.
Carefully smooth it out with a spatula if needed. Pop the pan back into the oven and bake for 25–30 minutes. The custard should be just set but still a little jiggly in the center.
Let it bake until it’s golden and firm around the edges. No need to worry if it wiggles a bit! It will set more as it cools.
Step 6: Cool and Slice
Once done, remove the pan from the oven and cool it on a wire rack until it’s completely at room temperature.
For the best flavor, refrigerate the bars for at least an hour before serving. Once chilled, dust the top with powdered sugar and slice them into 16 bars.
Enjoy these tantalizing bars cold, or at room temperature. They’ll disappear faster than you can say “Key Lime Bars Citrus Treat!”
Tips for Success
- Always use fresh key lime juice for a vibrant flavor that stands out.
- Let your eggs reach room temperature for better mixing and a smoother custard.
- Chill the bars before slicing to achieve clean cuts and a refreshing taste.
- Don’t skip the parchment paper; it makes removing the bars a breeze!
- For added flair, garnish with extra lime zest or serve with whipped cream.
Equipment Needed
- Baking pan: A 9×13 inch pan works best, but an 8×8 inch pan is a good alternative for thicker bars.
- Mixing bowls: Use two large bowls for mixing; one for the crust and one for the custard.
- Whisk: A regular whisk or an electric mixer makes blending easier.
- Parchment paper: Essential for easy bar removal; aluminum foil can be a substitute in a pinch!
- Cutting board: For slicing the bars neatly once they’ve cooled.
Variations
- Gluten-Free Option: Substitute all-purpose flour with a gluten-free blend to enjoy the same tart flavor without the gluten.
- Coconut Twist: Add 1/2 cup of sweetened shredded coconut to the crust for a tropical vibe that pairs wonderfully with the lime.
- Berry Blast: Top the Key Lime Bars with fresh strawberries or blueberries for an extra burst of flavor and color.
- Vegan Version: Substitute eggs with a mixture of flaxseed and water or silken tofu blended until smooth and use coconut cream instead of butter.
- Add Spice: A teaspoon of ground ginger or cinnamon in the crust can add a delightful warmth to the flavor profile.
Serving Suggestions for Key Lime Bars Citrus Treat
- Serve with a dollop of whipped cream for added richness that complements the tangy bars.
- Pair with a refreshing glass of iced tea or lemonade to enhance the zesty flavor.
- Garnish with lime slices or fresh mint leaves for a gorgeous presentation.
- Enjoy alongside fresh fruit, like strawberries or raspberries, for a colorful contrast.
