Frozen Key Lime Pie. What sets this frozen pie recipe apart is the creamy filling that sets to a luscious, creamy consistency. Makes a perfect cool summer treat or welcome dessert at any time of year.

Frozen Key Lime Pie
I’ve seen many recipes over the years for this style of frozen key lime pie. I decided to put my own twist on it with a vanilla cookie crust and a little whipped cream folded into the mix to lighten up the texture even more.

Lime desserts are probably tied with lemon as my favourite citrus flavours.
Sometimes frozen desserts can be a little annoying because they freeze hard as a rock. Then, they need to be taken out of the freezer to warm up for 20 minutes or so before serving.
Getting the timing right on those is sometimes a pain in the butt when you have guests waiting in eager anticipation.

A graham crumb crust in a springform pan holds the filling.
This pie doesn’t freeze terribly hard at all so it is easy to cut and has a very refreshing creamy finish. The fact that it’s frozen means that you can make it days in advance of any summer event.

Frozen Key Lime Pie
It would be terrific to take along to any summer barbecue that you get invited to; heck make one and you are sure to get several invites. Perfect to have in the freezer to for dessert at a moment’s notice too.
It is an ideal cool summer treat, yes, but don’t just reserve it for the warmer months. Since this is quite a large dessert, it’s one you can serve anytime, even at special occasions like Thanksgiving, where it would be a welcome addition to a more traditional pie.

If using half this recipe, how many egg yolks should be used?
Thanks, Kim

No, it is frozen so that's one safety plus whipping egg yolks with sugar denatures the proteins.

Whipping the egg yolks with the sugar denatures the protein strands in the egg yolks in the same way that cooking does...and it's frozen anyway.

@Barry C. Parsons, Sorry but this is not true. There is still a risk of Salmonella if egg yolk is whipped with sugar. Also, only heat kills Salmonella, freezing does not.
