Start by mixing all the crust ingredients together in a bowl.
Spread the mix on a pie pan evenly to make the layer of crust. Transfer the pan to a preheated oven at 350F for 7 minutes. Leave the pan to cool for 30 minutes.
Beat together the egg yolks, sweetened condensed milk and the key lime juice till a smooth consistency is formed.
Spread the filling on the crust and bake for another 15 minutes.
After removing the pan from the oven, let it cool for 30 minutes, then transfer to the fridge to chill for at least 8 hours.
Whisk with a stand mixer the sugar and heavy cream together, then add the vanilla extract for final flavor. Beat till the whipped cream form.
Decorate your pie. Slice it up and enjoy!
