The best key lime pie has the most amazing graham cracker shortbread crust, a perfectly creamy and tart filling, and homemade whipped cream. It is simple to prepare and oh, so good!
In a stand mixer, beat together butter, honey, brown sugar, and vanilla. Add in flour and salt and mix until combined. Don't overwork it. Mixture will be crumbly.
Press the mixture into a 9-inch standard pie plate. Bake for 7 minutes.
Key Lime Filling
Lower the oven temperature to 350 degrees Fahrenheit.
In a stand mixer, mix the egg yolks by themselves for 1 minute on medium-high speed. Add in heavy cream and mix again for 1 full minute on medium-high speed. It should appear fluffy.
Add in the sweetened condensed milk and mix for 1 minute on medium-high and then add in key-lime juice. Mix for another 30 seconds on a low-medium speed.
Pour the mixture into the prepared pie shell. Bake for 15 minutes or until filling is set.
Let cool for 1 hour before moving to the fridge to chill completely, about 4 more hours. Top with whipped cream and enjoy!
Whipped Topping
Combine the heavy whipping cream and powdered sugar in a bowl and whip until it forms stiff peaks.
