How to Make Key Lime Bars Citrus Treat
Now let’s embark on this delightful journey of creating Key Lime Bars Citrus Treat! Each step is simple, allowing you to whip up these beauties in no time. Roll up your sleeves, and let’s get cooking!
Step 1: Preheat and Prepare
First things first, preheat your oven to 350°F (175°C). This ensures even baking. While it warms up, take a 9×13-inch baking pan and line it with parchment paper. Greasing it first helps the paper stick. Don’t skip this step—nobody wants a delicious key lime bar stuck to the pan!
Step 2: Make the Shortbread Crust
Next, we’ll create our wonderfully buttery shortbread crust. In a mixing bowl, combine softened unsalted butter, granulated sugar, and all-purpose flour. Using a hand mixer or stand mixer, beat these ingredients until they’re light and fluffy—about 2 to 3 minutes. It should be like a fluffy cloud!
Once it’s mixed, gently press this dough evenly into the prepared pan—don’t worry about being perfect. Chill it in the refrigerator for about 15 minutes. While it chills, you can enjoy a cup of coffee! After that, bake the crust for 15 to 20 minutes. You’ll know it’s ready when it’s lightly golden—just the perfect touch for our citrus treat.
Step 3: Prepare the Key Lime Filling
Now, let’s turn our attention to that tangy key lime filling! In another large bowl, whisk together the eggs, granulated sugar, all-purpose flour, fresh key lime juice, and zest. Make sure everything is blended well and smooth. This mixture is what makes your bars heavenly, so don’t rush it. Feel the texture change as it comes together!
Step 4: Bake the Bars
With our filling ready, pour it gently over the cooled shortbread crust. Now, it’s time for the magic to happen. Return the pan to the oven and bake for another 25 to 30 minutes. Keep a close eye on it! The filling should be set but still jiggles slightly in the center when done. Trust me, it’s worth it!
Step 5: Cool and Serve
Once out of the oven, allow the bars to cool in the pan completely. This step is crucial! For even better flavor, I suggest chilling them in the refrigerator for a while. Once chilled, dust the top with powdered sugar to add that touch of elegance. Slice into 16 bars, and voilà! Your refreshing Key Lime Bars Citrus Treat is ready to impress.
Tips for Success
- Always use room temperature eggs for a smoother filling.
- Substitute fresh key lime juice with bottled if needed, but fresh is best!
- Chill your crust for a firmer base before adding the filling.
- Don’t overbake—pull them out when the center has a slight jiggle!
- Dust with powdered sugar before serving for that gorgeous finish.
Equipment Needed

- Hand or stand mixer: Whisking by hand works, but a mixer saves time;
