Step 1

Preheat oven to 375 °F and set an oven rack in the middle position.

Step 2

You can crush the graham crackers either by placing them in the plastic bag and crushing them with a rolling pin or with a food processor.

Step 3

In a large bowl, combine the graham cracker crumbs, brown sugar, and melted butter. Start by mixing with a fork, and then use your hands until the mixture is combined through.

Step 4

Using your hands and a bottom of a glass, press the mixture firmly into the sides and bottom of your 9" x 1.5" inch deep pie pan. The crust should be about 1/4" thick.

Step 5

Bake for 10 minutes or until slightly browned.

Step 6

Let the crust cool on a wire rack.

Step 7

Preheat the oven to 325 degrees.

Step 8

Gently whisk the 6 egg yolks (just barely) in a medium bowl.

Step 9

Combine the egg yolks with the sweetened condensed milk. (This mixture should be thin).

Step 10

Whisk or mix the eggs and milk on a low setting of a hand mixer while adding in juice. The mixture will get thicker in a minute or two because of a chemical reaction between the juice and dairy.

Step 11

Place the filling into the crust.

Step 12

Bake the pie for 15 minutes.

Step 13

Let cool.

Step 14

In a large bowl, beat the heavy cream with an electric mixer until the cream makes soft peaks. (You could also use a stand mixer with the whisk attachment).

Step 15

Then, mix in the confectioners' sugar and beat until you can see stiff peaks.

Step 16

Once the pie is cooled, you can decorate with the whipped cream topping.

Step 17

You can also top this amazing key lime pie with key lime zest, thinly sliced lime wedges, lime gummies, or even white chocolate shavings if you want.
