Deliciously smooth no bake key lime pie made from scratch with simple ingredients.

Cream cheese, sweetened condensed milk, and key lime juice team up to create a creamy and flavorful no bake dessert.

Easy No Bake Key Lime Pie Crust

This key lime pie is incredibly easy to make and it’s incredibly easy when using a hand or stand mixer. This crust for this no bake treat is made with crushed graham cracker crumbs, granulated sugar, and melted butter.

TIP: Skip the graham cracker crumbs and place graham crackers in a food processor or in a Ziploc bag and crush them with a rolling pin.

Those three ingredients combine together to create a graham cracker crust that is crunchy and sweet. To make this a truly no bake dessert, freeze the crust while preparing the other ingredients instead of baking the crust in the oven for a few minutes.

If you do want your crust to be on the crunchier side, bake the prepared crust in the oven at 350° for about 7 minutes or use a store-bought prepared crust. If baking the pie crust, remove it from the oven and allow it cool while preparing the filling.

How to Make No Bake Key Lime Pie

Make the Graham Cracker Crust: The first step in making this key lime pie is to prepare the graham cracker crust. To make the crust, combine the graham cracker crumbs (store-bought or homemade) and the granulated sugar.

Pour in the melted butter into the crumbs and stir so that all of the crumbs are moistened. Press the prepared crumbs into a 9-inch pie plate and use the back of a measuring cup to evenly press the crust onto the bottom and up the sides of the pie plate.

TIP: For a thinner filling and a wider pie, use a pie dish like this one. It is the one used in this post.

Prepare the Filling: Using a hand mixer or a stand mixer makes preparing the filling for this key lime pie quick. Heavy cream is beaten until stiff peaks begin to form. This will take a long time if done by hand but just a few minutes when using a stand or hand mixer.

In a separate bowl, beat the softened cream cheese until smooth and add the granulated sugar, key lime juice, and zest as well as the sweetened condensed milk. Once the ingredients are smooth, gently fold the whipped cream into the cream cheese mixture.

Spread the prepared filling evenly into the prepared graham cracker crust and use a silicone spatula to smooth the filling.

Chill the No Bake Pie: Chill the no bake key lime pie in the refrigerator for at least two hours before removing and decorating.

Top the chilled key lime pie with cool whip and decorate with thinly sliced key limes (limes) if desired.
