How to store Key Lime Pie Bars

Tips to make Key Lime Pie Bars
- Use fresh lime juice for the best flavor. Bottled lime juice lacks the bright taste that fresh limes provide.
- Keep an eye on the baking time to avoid overcooking, as it can make the bars dry.
- For a thicker crust, increase the amount of graham cracker crumbs slightly and press them firmly into the bottom of the pan.
Variation
You can add a swirl of meringue on top before baking for a twist on the classic recipe. Alternatively, consider adding shredded coconut to the crust for a tropical touch.
