This 3 ingredient no-bake key lime pie makes my mouth water just thinking about it!
Ingredients:
- 1 can of sweetened condensed milk
- ½ cup of key lime juice
- 8 ounces of Cool Whip or 1 cup of freshly whipped cream
And one 1 graham cracker pie crust.
How to Make 3 Ingredient Key Lime Pie:
- In a large bowl or stand mixer, add the sweetened condensed milk and the lime juice. Mix with the whisk attachment until the mixture is thick. I use a stand mixer on medium speed and let it mix for about 5 minutes to make the mixture a light and fluffy. You could use a hand mixer or food processor in a pinch.
- When the mixture is thick, add the 8 ounce of Cool Whip (what my grandmother would’ve done) or whipped cream (what my mom would do) into the mixing bowl. Fold together until everything is well mixed.
- Pour the creamy filling into the pie crust. Cover with plastic wrap and place it into you refrigerator for 1 hour. It will harden a bit as it cools and sets.
- After an hour, cut slices and serve.
Enjoy a slice of pie with a dollop of Cool Whip on top or garnish with a lime slice on top! For presentation purposes, you can also make a lime twist for the center of the pie which is a thin slice of the lime peel twisted. This tart and sweet dessert with simple ingredients is perfect for summer months.
Recipe Notes:
What will really make this a key lime pie recipe from Key West is using fresh key limes which are a little more tangy than regular supermarket Persian limes. If you have access to fresh key limes at your grocery stores, squeezing them would take this recipe up a notch so feel free to do that and while you are at it, add a 1/2 teaspoon of key lime zest while you have fresh limes. But if not, don’t sweat it! This recipe works just fine with regular limes or even the pre-squeezed regular lime juice that comes in the lime bottle. That couldn’t be easier and it still works just fine.
You can use a store bought graham cracker crust or you can make a homemade graham cracker crust (with just melted butter and graham cracker crumbs). Either way that sweet crunchy crust goes great with the creamy lime filling.
A more traditional key lime pie uses egg yolks but here we use cool whip or heavy cream for a creamier, lighter pie.
You may wish to garnish with lime slices or a swirl of lime peel.
