Equipment

9x13 inch baking pan
Parchment paper
Mixing bowls
whisk
spatula
Measuring cups and spoons
Knife

Ingredients

1 1/2 cups graham cracker crumbs
1/3 cup granulated sugar (for crust)
6 tbsp unsalted butter, melted
4 large eggs
1 2/3 cups granulated sugar (for filling)
2/3 cup key lime juice
2 tbsp lime zest
1/3 cup all-purpose flour

Instructions

Preheat oven to 350°F (175°C) and line a 9x13-inch baking pan with parchment paper.
Mix graham cracker crumbs, sugar, and melted butter until combined.
Press mixture firmly into the pan and bake for 10 minutes until lightly golden.
In a bowl, whisk eggs and sugar until smooth.
Add lime juice and zest, then whisk in flour until smooth.
Pour filling over warm crust.
Bake for 20–25 minutes until edges are set and center slightly jiggles.
Cool completely, then refrigerate for at least 2 hours.
Lift from pan and slice into bars before serving.

Notes

Use fresh key lime juice for best flavor. Do not overbake—center should still jiggle slightly. Chill at least 2 hours before slicing. Use a hot knife for clean cuts. Store refrigerated up to 5 days.
