Key Ingredients for Key Lime Pie Bars
- For the crust:
- 1 ¾ cups graham cracker crumbs
- ½ cup granulated sugar
- 1/2 cup unsalted butter, melted
- For the filling:
- 2 cans (14 ounces each) sweetened condensed milk
- ½ cup sour cream
- ¾ cup fresh Key lime juice (or regular lime juice if unavailable)
- Zest of 2 limes
- 3 large egg yolks
Step-by-Step Instructions
- Prepare your baking pan: Start by preheating your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving a little overhang to make lifting out the bars easier later.
- Make the crust: In a mixing bowl, combine the graham cracker crumbs, sugar, and melted butter. Stir until the mixture resembles wet sand. Firmly press this mixture into the bottom of the prepared pan to form an even layer. Bake the crust for about 10 minutes, until lightly golden. Remove from the oven and set aside to cool slightly.
- Prepare the filling: In another mixing bowl, whisk together the sweetened condensed milk, sour cream, Key lime juice, lime zest, and egg yolks until smooth and creamy.
- Combine and bake: Pour the filling mixture over the pre-baked crust, evenly spreading it out. Bake for an additional 15 minutes or until the filling is set but still slightly jiggles.
- Cool and slice: Remove from the oven and allow the bars to cool completely at room temperature. Afterward, refrigerate for at least 2 hours or until chilled. Once set, lift the bars out using the parchment paper, slice into squares, and serve!
What to Serve Key Lime Pie Bars With
These Key Lime Pie Bars are perfectly delightful all on their own. However, if you want to take your dessert experience to the next level, try pairing them with a dollop of freshly whipped cream or some vibrant mixed berries that complement the tartness of the limes beautifully. Alternatively, a refreshing glass of iced tea or a fruity sparkling water makes a refreshing accompaniment. The combination of flavors will elevate your dessert table and create a mouthwatering experience for you and your guests!
Top Tips for Perfecting Key Lime Pie Bars
To perfect your Key Lime Pie Bars, keep these tips in mind. First, always use fresh Key limes for the best flavor; however, if you can’t find them, regular limes work just fine. Be sure to zest the limes before juicing them to maximize flavor. Second, let the bars chill for a sufficient time in the fridge; the longer they sit, the more flavors meld together. Lastly, avoid overbaking the filling—once the edges are set, it’s time to take them out. Happy baking!
Storing and Reheating Tips
Staying organized when it comes to storing your Key Lime Pie Bars is easy! Simply refrigerate any leftovers in an airtight container for up to five days. If you’re looking to save them for later, you can freeze them for up to three months. Just be sure to wrap them in plastic wrap and foil for best results. When ready to enjoy, thaw them in the refrigerator overnight and serve chilled for the optimal taste experience.
