Ingredients

Graham Cracker Crust

1½ cups graham cracker crumbs
1/3 cup granulated sugar
6 tablespoons butter melted

Key Lime Pie

2 cans (14 oz each) sweetened condensed milk
1/2 cup sour cream
3/4 cup key lime juice (see notes)
zest from 2 limes

Whipped Cream

1 cup heavy whipping cream
1/2 cup powdered sugar
zest from 1 lime optional for garnish

Instructions

Heat oven to 350°.
In a small bowl mix together all the graham cracker crust ingredients and stir until it's well combined. Press into a 9-inch pie plate.
* You want to get a tight crust so press it really well into the pie plate. Use the flat underside of a measuring up to get it pressed into the pie plate well.
Cook for 7 minutes. Let the crust cool while you prepare the filling.
In a large bowl add the sweetened condensed milk, sour cream, key lime juice, and lime zest. Stir with a whisk until it's combined well and smooth.
Pour into the graham cracker crust. Bake for 10 minutes.
Let the pie cool for about 20-30 minutes and then cover with saran wrap. Make sure that the saran wrap is touching the top of the key lime pie to prevent condensation from the refrigeration time.
Refrigerate for at least 6 hours or overnight.
When ready to serve beat the heavy whipping cream and powderd sugar in a bowl until stiff peaks form. This will take several minutes. Start on LOW speed and increase speed as needed as the cream gets thicker.
Pipe the whipped cream onto the pie (as pictured) or serve each slice with a dollop of whipped cream. You can also just use the spray whipped cream in a can if wanted.

Notes

Sour Cream : Feel free to use lite sour cream in this recipe. I think the full-fat sour cream gives a thicker and richer texture but lite sour cream will work just as well.

Key Lime Juice : This is not the same thing as lime juice. You will find it in the juice aisle and it's by the brand name of 'Nellie and Joes Famous Key Lime Juice'.

Lime Zest : When zesting a lime be sure and wash it first with water and only grate the outermost layer of the lime. You don't want to grate more than that (the white part) because it's really bitter. Just grate the outer green part one time and move on.
