Key lime pie is a no-fuss custard pie made with fresh lime juice, sweetened condensed milk, and egg yolks poured into a graham cracker crust. The filling sets firm in about 15 minutes in the oven, then the pie chills until cold — plan for at least 2 hours of refrigeration before serving.

Instructions
Preheat your oven to 350°F (175°C).In a mixing bowl, combine 1 and 1/2 cups of graham cracker crumbs, 1/3 cup granulated sugar, and 6 tablespoons melted unsalted butter. Mix until the crumbs are evenly coated with butter.
Press the mixture firmly into the bottom and sides of a 9-inch pie pan, creating an even layer. Bake for 10 minutes or until lightly browned and fragrant.
In another bowl, whisk together 1 cup of sweetened condensed milk, 1/2 cup key lime juice, 1 tablespoon lime zest, and 4 egg yolks until smooth and well combined.
Pour the filling mixture into the pre-baked crust, spreading it evenly. Bake for an additional 15 minutes, or until the center is set but still slightly jiggly.
Allow the pie to cool at room temperature, then refrigerate for at least 2 hours before serving to fully set the filling.

Notes
Tammy’s Tips
For a more vibrant flavor, consider adding a few drops of pure vanilla extract to the filling.
If you cannot find fresh key limes, regular limes will suffice, though the flavor will be slightly less intense.
For a dietary-friendly version, use gluten-free graham crackers and substitute coconut milk for those with lactose intolerance.
