How to Serve Key Lime Pie Bars
Key Lime Pie Bars are best served chilled. You can cut them into squares or rectangles for easy serving. Top each bar with a dollop of whipped cream and a sprinkle of lime zest for a beautiful presentation. They pair well with fresh fruit, making them a perfect choice for a summer dessert.
How to Store Key Lime Pie Bars
To store your Key Lime Pie Bars, keep them covered in the refrigerator. They will stay fresh for up to five days. If you would like to freeze them, wrap the bars tightly in plastic wrap and then in aluminum foil. Frozen bars can last up to three months. Just be sure to thaw them in the fridge before serving.
Tips to Make Key Lime Pie Bars
- Use fresh key lime juice for the best flavor. If you can’t find key limes, regular lime juice will work too.
- For a thicker crust, increase the amount of graham cracker crumbs by half a cup.
- Don’t skip the chilling time! Allowing the bars to set properly will enhance their texture and flavor.
Variation
You can add a twist to these bars by mixing in coconut or crushed pineapple for a tropical flavor. Another option is to add a layer of meringue on top for an extra touch of sweetness.
