Key Lime Pie with Pecan Shortbread Crust – Gluten Free

gluten free

How could I have been so busy at to miss something as significant as National Pi Day?! Blasphemy!

Not that I need excuse to eat pie, but I did need an excuse to actually make a pie in the middle of the week.

There it was…and I missed it.

If you don’t know what National Pi Day is, click here for a fun explanation.

Inspired by National Pi Day and St. Patty’s day all in one week, I decided to make Key Lime Pie. Well, it’s kind of green.

But, this wasn’t just any key lime pie. This was one with a Pecan Shortbread cookie crust – and it was gluten free!

I made a basic butter cookie crust with Pameal’s Pecan Shortbread Cookies. Then I used the Shirriff brand, Dr. Oetker, Key Lime Pie Filling an Dessert Mix and topped it with merengue.

This isn’t one of the “instant” pudding mixes and requires you to boil water to make the filling, but I promise it’s not that intimidating.

It came out absolutely delicious.

I was tempted to color it more “green” for St. Patty’s day, but decided it didn’t need any additional artificial colors or flavors.

Any gluten free cookie would work okay – but key lime pies usually have a graham cracker or vanilla wafer cookie crust, so I chose a really great shortbread cookie.

Using a chocolate cookie crust or gf flour pie crust starts to get farther away from the traditional key lime pie ensemble.

Next year, I think I’ll devote the whole week to pie!
