Why you will love this Easy Key Lime Recipe:

1. This pie recipe has it all…a creamy texture, tangy yet sweet flavor, all paired with a buttery graham cracker crust.
2. It calls for simple ingredients and is super easy to make so bakers of all skill levels can make this homemade key lime pie.
3. It stores super well so you can store any leftover pie covered in the refrigerator.

Tips for making the Best Key Lime Pie:

Chill the pie for at least 4 hours before serving to allow the flavors to meld and the texture to firm up.

Use fresh key limes for the best flavor. If you can’t find key limes, regular limes can be substituted, though the flavor will be slightly different.

Don’t overbake the filling; it should be set but still slightly wobbly in the center.

Easy Key Lime Pie Ingredients:

A traditional key lime pie is made with sweetened condensed milk, key lime juice, lime zest, and egg yolks in a graham cracker crust. The best key lime pie is made with a secret ingredient — sour cream. It is what gives it the rich, creamy texture without adding more sweetened condensed milk. It perfectly balances out the sweetness of the sweetened condensed milk!

Graham Cracker Crust:

• Graham Cracker Sheets
• Salted Butter (melted)

The graham cracker crust is made with two simple ingredients — crushed graham crackers and melted butter. I prefer to use salted butter to balance out the sweetness of the filling so if you use unsalted butter, add a pinch of salt.

Key Lime Pie Filling:

• Sweetened Condensed Milk
• Egg Yolks
• Sour Cream (preferably full-fat)
• Key Lime Juice (or regular limes)
• Zest from 1 Lime

Homemade Whipped Cream:

• Heavy Cream
• Powdered Sugar

I love adding fresh sweetened whipped cream to my key lime pie. This is made by whipping heavy cream until soft peaks form and stirring in powdered sugar. It is so simple but is a must with this key lime pie recipe.

How to Make the Best Key Lime Pie with Graham Cracker Crust:

This homemade key lime pie recipe is made with a buttery graham cracker crust, a sweet, tangy, and creamy key lime filling, perfectly balanced with sweetened condensed milk, and topped with fluffy whipped cream. This is such an easy key lime pie recipe and is always a hit!

Graham Cracker Crust:

• Preheat oven to 350 degrees. In a food processor, pulse graham crackers until fine crumbs. Stir in melted butter and continue to pulse. If you don’t own a food processor, place graham crackers in a large Ziploc bag and crush using a rolling pin until fine crumbs. Pour into a bowl and stir in melted butter.
• Press firmly into a 9-inch pie pan, using the back of a measuring cup or small glass. Bake at 350 degrees for 8 minutes. Set aside to cool.

Key Lime Pie Filling:

• In a medium bowl, whisk together sweetened condensed milk, egg yolks, lime juice, lime zest, and sour cream. Pour into the graham cracker crust and bake for 10 minutes.
• Let it CHILL. It is important to allow it time to chill in the refrigerator because this allows it to set-up. It needs at least 4 hours before slicing the pie.

HOMEMADE WHIPPED CREAM:

• In a large bowl, whip heavy cream until soft peaks form. Fold in powdered sugar. Add a dollop of whipped cream to each piece or pipe over the entire pie. Garnish with fresh lime slices.

How to Decorate Your Key Lime Pie:

Keep the decoration simple to let the refreshing citrus flavor shine:

• Whipped Cream: A classic topping that adds a light, sweet contrast to the tart filling.
• Lime Zest & Slices: Sprinkle lime zest over the top and add a few quartered lime slices for a burst of color.
• Macadamia Nuts or Graham Cracker Crumbs: For added texture, scatter whole macadamia nuts or extra graham cracker crumbs over the whipped cream.

FAQ’s:

1. Can I make key lime pie ahead of time?

Yes! Key lime pie is best made a day in advance, allowing it to chill and the flavors to develop.

2. What’s the difference between key limes and regular limes?

Key limes are smaller, have a thinner skin, and are more aromatic and tart compared to regular limes. They are also slightly yellow when ripe. Can I use regular limes instead of key limes? You can substitute regular limes with key limes if you can’t find key limes.

3. How do I know when my key lime pie is done baking?

The edges should be set while the center has a slight jiggle. It will continue to set as it cools.

4. How do I keep the pie from cracking?

To avoid cracks in the filling, don’t overbake the pie. Bake it just until the center is slightly jiggly, then allow it to cool slowly.

How to store homemade Key Lime Pie:

Refrigerator: Store any leftover key lime pie in an airtight container in the refrigerator for up to 3-4 days.

To serve chilled icebox key lime pie, cut into wedges and garnish with fresh whipped cream and lime slices.
