Start by preheating your oven to 375°F. While the oven gets ready, gather and measure all your ingredients. Having everything prepped in advance ensures a quicker and smoother process.

Combine the egg yolks, sweetened condensed milk, and key lime juice in a mixing bowl. Use a whisk to blend everything until smooth and creamy. If you enjoy a brisker tang, add an extra splash of lime juice or a bit of zest.

If you’re using a ready-made graham cracker crust, you can jump straight to the next step! For homemade crusts, mix graham cracker crumbs with melted butter and a touch of sugar, pressing it into a pie dish using the back of a spoon. Ensure the layer is even and compact for a sturdy base.

Pour the lime filling into the prepared crust, using a spatula to spread it evenly. Bake the pie for 15 minutes, until the filling appears set but still jiggles slightly when you move the dish. This consistency is key to a luscious dessert.

Allow the pie to cool completely at room temperature after baking. Then refrigerate it for at least 3 hours or, better yet, overnight. Trust me, the cooling time makes a huge difference in the final flavor and texture.

Before serving, decorate your pie with whipped cream, lime zest, or thin lime slices for a fresh and inviting look. Slice it up, share with loved ones, or enjoy your moment of citrusy bliss solo!
