This easy Key Lime Pie is tart and sweet, super creamy and bursting with fresh lime flavor. We use a homemade graham cracker crust as the base, filling it to the brim with a smooth and creamy no-bake filling.
In a large mixing bowl, combine the melted butter, graham cracker crumbs, sugar, and cinnamon (if using). Mix well with a spoon or spatula.
Transfer the mixture into a 9" pie plate and press firmly into the bottom and sides using the bottom of a measuring cup.
Bake in a preheated oven for about 8 minutes, or until lightly golden.* Remove from the oven and let cool completely before filling.
Key Lime Pie
In the bowl of a stand mixer, whip the heavy cream until soft peaks form. Transfer to a separate bowl and set aside.
Add the room temperature cream cheese to the stand mixer bowl and beat until fluffy using the paddle attachment. Turn off the mixer and add the sweetened condensed milk, lime juice, and lime zest, then mix on low to combine. Increase speed to medium and beat again until fluffy and smooth.
Gently fold in the whipped cream with a spatula, then pour the filling into your prepared graham cracker crust.
Refrigerate at least 2 hours, or until ready to serve. Top with fresh whipped cream and lime slices before slicing and serving. Enjoy!
Notes
*For a no-bake graham cracker crust, freeze for at least 1 hour instead of baking in the oven.
