What Is Key Lime Pie?

Key lime pie is an American dessert that originated in Key West, Florida, and is traditionally made with, you guessed it, key limes. The lime juice is then blended with condensed milk, and eggs (just whites for this recipe) and then baked into a buttery graham cracker crust that gives it a mouth-watering flavor combination.

Ingredients

Limes- For this recipe, we will be using regular limes however, if you would like to use key limes you can. You will need about 1/2 cup of lime juice in total.

Condensed Milk- Using sweetened condensed milk will help sweeten and set the pie.

Sugar- White sugar is best for making the crust as it helps give the crust a nice crunch.

Graham Crackers- This recipe calls for plain graham crackers, you will need 12 sheets. You can also use cinnamon crackers to add a little warmth if you like.

Eggs- Use large eggs. If you have small or medium-sized eggs, I suggest you use 5 egg whites to ensure you have enough for the filling.

Butter- I use salted butter for this recipe. If you would like to use unsalted I suggest adding 1/4 tsp of salt to balance out the flavors for the crust.

What You Will Need To Make It

Filling

5 limes juice and zest

1- 14oz can of sweetened condensed milk

4 large egg whites

Graham Cracker Crust

1/4 cup white sugar

12 graham crackers

10 tbsp of melted salted butter

Tools

stand mixer or hand mixer (to whip the egg whites)

9″ springform pan

Directions

Begin by making the crust. Melt the butter in a saucepan. Brush a springform pan with the melted butter. Add the graham crackers, remaining melted butter, and sugar to a food processor.

Process until the crackers turn into fine crumbs that look like wet sand.

Pour the mixture into the springform pan and press it down to smooth it out with the back of a spoon. Set aside.

Zest and squeeze the juice from the limes.

Separate the eggs and add the four whites to a mixer bowl. Whip the egg whites until soft peaks form. Pour in the condensed milk, lime juice, and half the zest. Save the rest of the lime zest for garnishing. Mix until smooth.

Pour the mixture into the springform pan. Bake at 350℉ for 20 minutes.

Chill before serving. Garnish with lime zest.

Baking Notes

• Be sure to whip the egg whites until stiff otherwise, the pie will not set properly.
• Allow the key lime pie to cool to room temperature before placing it in the fridge.
• To remove from the springform pan, run a knife along the sides before unlatching the pan to help release it from the sides.
• Garnish with lime zest for a pretty presentation.

FAQ

How long does key lime pie last?

Store your key lime pie in an air-tight container and if possible place it in the fridge’s vegetable drawer. It will keep for up to a week.

Can you freeze key lime pie?

Key lime pie is best when made fresh and the good news is, it’s one of the simplest pies you can make. I can have one whipped up and ready to go in the oven in 15 minutes! However, you can freeze it in an air-tight container and it should keep for up to 3 months. To thaw, remove the key lime pie from the freezer and keep it in the fridge for a day or so.

Can I make this key lime pie dairy free?

My 6 Ingredient Key Lime Pie will definitely need the condensed milk to set right however this recipe from Simply Whisked, Dairy Free Key Lime Pie looks like a great alternative to check out.
