Ingredient Breakdown

When making an authentic Florida Key Lime Pie, it’s vital to use fresh, high-quality ingredients.

Crust Ingredients

I always start with a graham cracker crust.

You’ll need about 1 1/2 cups of graham cracker crumbs, which come from roughly 10 full-sized graham crackers.

Crush them finely, then mix in about 1/3 cup of granulated sugar and 6 tablespoons of melted butter.

For an extra touch, some people like adding 1/4 cup of crushed pecans to the mix for added texture and flavor.

Once combined, press this mixture firmly into your pie pan and bake it for about 10 minutes at 350 degrees until it’s set. This gives the pie a sturdy base and a slightly toasted flavor that’s simply delicious.

Filling Ingredients

The filling is where the magic happens. Authentic Key Lime Pie filling requires fresh key lime juice.

About 1/2 to 2/3 cup of freshly squeezed juice is needed, which usually comes from 12-16 key limes.

In a mixing bowl, beat together 4 egg yolks with a can (14 ounces) of sweetened condensed milk.

Then, slowly add the key lime juice while mixing until everything is well combined.

Adding a teaspoon of lime zest gives an extra burst of citrus flavor, making every bite bright and tangy.

Topping Ingredients

For the topping, I prefer freshly made whipped cream over meringue.

Using an electric mixer, beat 1 cup of heavy cream with 1/4 cup of powdered sugar until stiff peaks form.

Some like adding a dash of vanilla extract for a rich flavor.

Spread this whipped cream over the cooled pie.

For the final touch, I sprinkle a bit more lime zest on top. It adds a refreshing look and an extra zing that perfectly balances the sweetness of the filling.

Step-by-Step Instructions

Making an authentic Florida key lime pie involves a few essential steps: preparing the crust, whipping the cream, assembling and baking the pie, and finally, chilling and serving it. Here’s how to do it all with ease and precision.

Preparing the Crust

First, I like to use a homemade graham cracker crust. It adds a wonderful texture and flavor.

In a 9-inch pie plate, I combined about 1 and 1/2 cups of graham cracker crumbs with 1/4 cup of sugar, and 6 tablespoons of melted unsalted butter.

I press the mixture firmly using the back of a measuring cup.

Then, I bake the crust at 350 degrees Fahrenheit for about 10 minutes until it’s golden and sets nicely.

After baking, I let it cool completely on a wire rack. This step is crucial for getting that perfect firm base for the pie filling.

Whipping the Cream

For the topping, I prefer to make homemade whipped cream instead of using store-bought whipped topping.

I take 1 cup of cold heavy cream and beat it in a large bowl using an electric mixer on medium-high speed.

Gradually, I add 3 tablespoons of powdered sugar and 1 teaspoon of vanilla extract.

I continue to beat until soft peaks form. Careful not to overbeat, as I want the cream to be light and airy. The homemade whipped cream pairs perfectly with the tartness of the key lime pie filling.

Assembling and Baking

Next, it’s time to prepare the filling and put everything together.

In a large bowl, I mix together 4 egg yolks, a can (14 ounces) of sweetened condensed milk, and 2/3 cup of fresh-squeezed key lime juice.

I use a hand mixer on medium speed for 1-2 minutes until the mixture is smooth and well combined.

Then, I pour the filling into the pre-baked crust.

I smooth the top with a spatula and bake it at 350 degrees Fahrenheit for about 15 minutes, or until the filling sets.

After baking, I let the pie cool on a wire rack before moving it to the refrigerator.

Chilling and Serving

Chilling the pie is essential for getting the right texture.

I cover the pie loosely with plastic wrap and let it chill in the refrigerator for at least 4 hours, or overnight if possible.

This resting time allows the flavors to meld together beautifully.

When it’s ready to serve, I top the pie with the homemade whipped cream.

Sometimes, I like to add a bit of lime zest on top for an extra burst of flavor and a touch of color. It’s the perfect finish to this classic key lime pie.
