How to Make Key Lime Pie Bars

Ingredients

  • 1.5 cups graham cracker crumbs
  • 6 tablespoons salted butter (melted)
  • 0.33 cup granulated sugar
  • 1 can sweetened condensed milk (14-ounce)
  • 5 large egg yolks
  • 0.5 cup fresh key lime juice
  • 2 tablespoons key lime zest
  • Powdered sugar (for dusting, optional)
  • 2 tablespoons key lime and/or lemon zest (for topping, optional)

Key Lime Pie Bars

Directions

  1. Preheat the Oven
    Begin by preheating your oven to 375°F (190°C). While the oven is heating, prepare an 8 or 9-inch square baking pan by spraying it with cooking spray and lining it with parchment paper. This will make it easy to remove the bars later.

  2. Make the Crust
    In a medium bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Mix well until the crumbs are evenly coated in butter and sugar. Press this mixture into the bottom of the prepared baking pan. Make sure to pack it down tightly so the crust holds together when baked. Bake for about 7 minutes, or until it turns lightly golden. Once done, remove it from the oven and let it cool.

  3. Prepare the Filling
    Lower the oven temperature to 350°F (175°C). In a separate bowl, whisk together the sweetened condensed milk, egg yolks, fresh key lime juice, and key lime zest. Mix until smooth and well combined. Pour the filling over the cooled crust, spreading it evenly.

  4. Bake the Bars
    Place the pan back into the oven and bake the bars for about 25 minutes. You’ll know they are done when the filling is set but still slightly jiggly in the center. After baking, remove them from the oven and allow them to cool at room temperature for a while. Once they have cooled down, refrigerate the bars for 2 to 3 hours. This chilling time helps them firm up nicely.

  5. Serve
    Before serving, dust the bars lightly with powdered sugar, if desired. For a finishing touch, sprinkle with extra zest from key limes or lemons. Slice them into squares or bars and enjoy!

How to Serve Key Lime Pie Bars

Key Lime Pie Bars are great for any occasion, whether it’s a family gathering, a picnic, or a casual dessert after dinner. To serve, cut them into square or rectangular bars and place them on a serving platter. You can garnish with additional key lime or lemon zest to enhance their appearance. Serve them chilled for the best flavor and texture. They pair wonderfully with a dollop of whipped cream on top or alongside fresh fruit like strawberries or raspberries.

How to Store Key Lime Pie Bars

To store Key Lime Pie Bars, keep them in an airtight container in the refrigerator. They will stay fresh for about 4 to 5 days. If you want to keep them longer, you can freeze them. Wrap the bars tightly in plastic wrap and then place them in a freezer-safe container. They can be stored in the freezer for up to 2 months. When ready to enjoy, thaw the frozen bars in the refrigerator overnight.

Tips to Make Key Lime Pie Bars

  • Use Fresh Ingredients: The flavor of your bars will greatly improve with fresh key lime juice and zest. If key limes are not available, you can use regular limes, but the taste will be slightly different.

  • Don’t Overbake: Keep an eye on the bars as they bake. Overbaking can lead to a tough filling. It’s better to slightly underbake than overbake; they will continue to set as they cool.

  • Adjust the Sweetness: If you prefer a sweeter bar, you can add a little more sugar to the filling. Taste the filling before pouring it onto the crust to adjust the sweetness to your liking.

Variation

If you want to mix things up, consider some tasty variations. You can create a Coconut Key Lime Pie Bar by adding shredded coconut to the crust. Alternatively, for a more intense flavor, include a bit of cream cheese in the filling for added richness. Another option is to add a swirl of fruit puree, such as raspberry or mango, on top of the filling before baking for a colorful twist.

FAQs

Q: Can I make these bars ahead of time?
A: Yes, Key Lime Pie Bars can be made a day or two in advance. Just be sure to keep them refrigerated until you are ready to serve.

Q: What can I use if I can’t find fresh key limes?
A: If fresh key limes are not available, bottled key lime juice can be a good substitute. Regular limes can also work, but be aware the flavor will be different.

Q: How do I know when the bars are done baking?
A: The bars are done when the filling is set but slightly jiggly in the center. They will firm up more as they cool.

Q: Can I freeze leftover bars?
A: Yes! You can freeze Key Lime Pie Bars. Wrap them tightly and store them in an airtight container in the freezer for up to 2 months.

In summary, making Key Lime Pie Bars is a straightforward and enjoyable process that results in a refreshing dessert. With the right ingredients and approach, you can create a treat that’s perfect for any occasion. Whether you keep them for yourself or share them with friends and family, these bars are sure to be a hit!
