Gluten Free Key Lime Pie Recipe

gluten free key lime pie

This pie is a little runny but it is oh, so good.

My daughter has had her share of complaints since being diagnosed with Celiac. She can’t go to restaurants with her friends like she used too because so many of them do not have any gluten free items, she can’t have her favorite snacks, and she couldn’t have some of our favorite desserts because of the graham cracker crusts. I knew I could substitute gluten free baking mix for flour, but had no idea what to do for graham crackers.  We accidentally stumbled onto the idea to use Almond Meal instead of graham crackers and we were in business. Now she can enjoy traditional cheesecakes and pies instead of only eating the filling, which I would scoop out for her before putting in  pie crust for everyone else.  If you are watching calories, substitute artificial sweetener and low fat sweetened condensed milk.
For those of us who are not able to find Key Limes this time of year or don’t want to have to pay a premium price, just use regular limes. No one will know if you don’t tell.  The recipe also calls for raw egg yolks. I pick up some pasteurized eggs, but completely understand if you don’t want to use them and recommend using egg substitute. I’ve added the equivalent amount of egg substitute needed into the recipe. My mom made this when I was growing up and often substituted lemon juice when she was out of limes, which was almost every time. Be sure to make the sweetened whipped cream to put on top of this, because it is amazing. Life is too short not to have a pie with premium toppings.

Bobs Red Mill
 Bob’s Red Mill sent us a selection of gluten free products including Almond meal, Coconut flour, Xanthum Gum and Brown Rice Flour. They have been producing gluten free products for over 30 years and now have over fifty items available.  Through dedication, research and specialized machinery,  they have made sure their products are truly gluten free with no cross contamination.  Be sure to check out their video showing their story and their recipes. Humorously, my son told me he loved the crust in our pie. “It tastes like cookies,” he said.  “You realize this is gluten free?” I asked.  “Yep, tastes better than the normal graham cracker ones.” Woot! Score one for gluten free!

    We are not gluten-free, so I can’t comment on my favorite gluten-free food. I do think it’s great that there are so many options available now for going gluten-free, though.

    So glad you were able to find something to make pie for her! I tried going gluten free years ago (to combat IBD, didn’t work) and it was so hard. Good for you guys!

    Key Lime Pie is one of my favorites. I’m so glad you were able to alter this to make it something your daughter can enjoy. Have you seen the bottled Key Lime juice — they sell it at our local grocery store in the baking section.

    I use Red Mill to bake all the time, love their products just wish I did not have to order them over the internet and could get them at the store. I try to make everything GF that I can per doctors orders, your pie does not look bad and I would love to try to make it.

    Oh this looks super duper good! I would love to make this in a few weeks when the weather starts getting warm. It would be the perfect treat

    This pie looks delicious. My nephew was just diagnosed with some food allergies so he will be eating a gluten-free diet. I will be passing all of these recipes to my brother and his wife.

    My son has a very bad case of Chron’s and seems to do so much better when he sticks to a gluten free”ish” diet. I cannot wait to surprise him with this! Thank you and I hope your daughter does well in the future, it is so hard to not be able to “indulge” in the things your friends are, my son has had his fair share of that as well.

    I don’t know much about gluten free food but my cousin has to eat gluten free so I’m sending her to this post! I love pie & this seems like it is delicious!

    I didn’t realize Red Mill sold Xanthum Gum. My husband recently started using it in recipes but he had to order it from a specialty shop. I’ll have to check Red Mill when we’re ready for a refill!
