Does key lime pie contain gluten?
Some key lime pies are naturally gluten-free, but if you are buying a store-bought pie, it's best to double-check the ingredients to ensure the crust does not contain gluten. Store-bought pie crusts are often made with all-purpose or whole wheat flour, so be cautious of this. Generally, key lime pie filling naturally does not contain gluten.
Since this gluten-free key lime pie recipe uses gluten-free graham crackers for the crust, it does not contain gluten and is safe to enjoy if you have gluten allergies. It is also dairy-free and vegan!
You only need 7 ingredients to make the key lime pie. It is so easy and simple!
Here is some helpful information about the ingredients, with recommendations for substitutions you can make if necessary:
- Gluten-free graham crackers - There are a few gluten-free graham cracker options on the market. I recommend trying these gluten-free honeygrahams from Schar, but any gluten-free graham crackers should work. Be sure to ground them into a fine powder when making the crust.
- Melted vegan butter - This is a dairy-free key lime pie, so vegan butter is used in the crust. I use Earth Balance and Melt vegan butter the most. Either option should have good results. Make sure to melt it before mixing the crust.
- Fresh lime zest - Don't omit the lime zest! It adds such a strong, delicious lime flavor to the filling (even more than the lime juice).
- Lime juice - Freshly squeezed key lime juice is the best option for the filling, but you can use bottled lime juice if it is all you have on hand. It will still taste delicious!
- Canned coconut milk - Be sure to use canned coconut milk, not the drinking kind of coconut milk you find in the fridge. Full fat coconut milk is necessary for this recipe.
- Pure maple syrup - Maple syrup is a natural sweetener in the pie filling instead of using processed granulated sugar. You can use honey instead, if you aren't vegan.
- Cornstarch - This is necessary to thicken the key lime pie filling.
How to Make Gluten Free Graham Cracker Crust
The no-bake gluten-free graham cracker pie crust is made with just two ingredients: graham crackers and vegan butter! Here are instructions for making the pie crust:
STEP 1: Crush graham crackers. In a food processor or powerful blender, crush the gluten-free graham crackers into a fine, dusty powder. You want to avoid having big graham cracker chunks. Fine crumbs hold together the best.
STEP 2: Melt vegan butter. In a microwave-safe bowl, melt the vegan butter.
STEP 3: Combine crumbs and butter. In a large mixing bowl, stir together the gluten-free graham cracker crumbs with the melted butter until a sticky mixture forms. It should be "moldable" and damp.
STEP 4: Transfer to pie pan. Spray an 8 or 9-inch pie pan with non-stick cooking spray. Then, transfer the pie crust mixture to the pan. Use your fingers or the back of a spoon to smooth the crust evenly around the pan and up the edges.
STEP 5: Chill. Set the crust in the fridge for 10 minutes while you make the key lime pie filling. This is a no-bake graham cracker crust, which means you don't have to "set it" in the oven like other pie crust recipes might require. The fridge is fine!
How to Make Dairy Free Key Lime Pie Filling
The gluten-free, dairy-free key lime pie filling comes together on the stove in just a few minutes. Here are instructions for making the pie filling:
STEP 1: Add all ingredients to a saucepan. Over medium-high heat, warm the coconut milk, maple syrup, lime juice, lime zest, and cornstarch.
STEP 2: Reduce heat and stir. Once the mixture is heated, but not yet boiling, reduce to low heat and stir the mixture continuously for 4-8 minutes until it thickens. It should be smooth, thick, and creamy.
STEP 3: Remove from heat. Then, pour the thickened key lime pie filling into the prepared pie crust. Use a spoon to evenly spread the filling around the pie pan.
STEP 4: Chill the pie. The gluten-free key lime pie needs to set up for at least 5 hours in the fridge before serving. It's best to chill it overnight, but 5+ hours is fine.
Once chilled, consider topping the pie with dairy-free coconut whipped cream and fresh lime zest. You can garnish the pie with a few fresh lime slices, too.
Expert Baking Tips
- Chill pie completely - It's very important to let the key lime pie set up completely in the fridge before you slice and serve the pie. Be sure it has time to chill for at least 5 hours, for best results.
- Don't let the filling boil - When heating the pie filling ingredients on the stove, don't let the mixture boil. You want it to become warm, but not boiling.
- Finely crush graham crackers - Big chunks of graham crackers don't lend themselves to making a seal-proof pie crust. Be sure to finely ground the gluten-free graham crackers in a food processor or blender so it is easy to mix with the melted vegan butter and form a moldable pie crust.
- Use full fat coconut milk - You need to use canned coconut milk with fat in order for the key lime pie filling to thicken properly and set up.

How To Thaw A Frozen Pie
Remove the frozen pie from the freezer and let it thaw on the counter for 1-3 hours, until soft enough to eat. I do not recommend trying to thaw a frozen pie quickly by heating it in the microwave or oven, as this could cause the key lime pie filling to become sticky and melt.
