Instructions

Step 1: Prepare the Crust

Step 2: Make the Key Lime Filling

  2. Add the sweetened condensed milk and mix until fully combined.
  3. Stir in the key lime juice and lime zest, mixing until smooth.
  4. Pour the filling over the cooled crust and spread evenly.

Step 3: Bake and Chill

  1. Bake at 350°F (175°C) for 15 minutes, or until the center is set but slightly jiggly.
  2. Remove from the oven and let cool at room temperature for 30 minutes.
  3. Transfer to the refrigerator and chill for at least 2 hours, or overnight for best results.

Step 4: Slice and Serve

  1. Once fully chilled, lift the bars out using the parchment paper and place them on a cutting board.
  2. Slice into squares and top with whipped cream, extra zest, and lime slices.
  3. Serve and enjoy!

Tips for the Best Key Lime Pie Bars

  • Use Fresh Key Lime Juice: Fresh juice provides the best flavor, but bottled key lime juice works in a pinch.
  • Chill Thoroughly: The bars set better when refrigerated for several hours.
  • Use a Hot Knife: For clean slices, warm your knife under hot water and wipe it dry between cuts.

FAQs

1. Can I Use Regular Limes Instead of Key Limes?

Yes! Regular limes (Persian limes) can be used if key limes aren’t available. The flavor will be slightly less tangy but still delicious.

2. How Do I Store Key Lime Pie Bars?

Store them in an airtight container in the fridge for up to 5 days. You can also freeze them for up to 2 months.

3. Can I Make These Bars in Advance?

Absolutely! These bars actually taste better when made a day ahead, as the flavors develop while chilling.

4. What’s the Difference Between Key Limes and Regular Limes?

Key limes are smaller, have more seeds, and have a more intense, aromatic flavor compared to regular limes.

5. Can I Use a Different Crust?

Yes! While graham cracker crust is traditional, you can try crushed vanilla wafers, digestive biscuits, or even a shortbread crust for a twist.
