Ingredients For This No-Bake Keto Key Lime Pie
You will need only a few simple ingredients for this no-bake keto lime pie, which you may already have in your pantry:
For the Crust
To make the crust for this pie, I used an almond flour mixture, but you can also use my keto graham crackers to replicate the original pie crust recipe.
- Almond Flour- is my favorite keto flour alternative for no-bake keto recipes. Be sure you use almond flour instead of almond meal. If you don’t have almond flour on hand, grind some almonds in your food processor and use it instead.
- Sweetener- Any keto powdered sweetener, such as erythritol, xylitol, monk fruit, or allulose, can be used. Just make sure you’re using a powdered form, so it blends easier.
- Butter- replace it with coconut oil.
- Vanilla Extract- I recommend using a high-quality vanilla extract you can get.
- Cinnamon- optional, but make the crust taste like a graham cracker crust.
For the Lime Filling
- Lime Juice- Freshly squeezed. Lime is very accessible and can be found in all stores.
- Gelatin Powder- is used to set the filling mixture.
- Cream Cheese- for the smoothest filling, make sure that the cream cheese is at room temperature.
- Lime Zest- this is optional, but I used it for an extra flavor.
- Heavy Cream- room temperature for easier mixing.
- Vanilla Extract- this ingredient is never missing from my desserts, but you can replace it with some lime extract.
- Sweetener- use powdered sweetener for the filling to avoid any lumps.
How To Make This Delicious No-Bake Keto Lime Pie
If you follow the next few easy steps, you will end up with one of the best keto desserts you will ever try.
- Start by making the keto pie crust: Combine all the ingredients for the crust until you have a sandy mixture.
- Press evenly into the bottom of a pan and chill while preparing the filling.
- Make the keto key lime filling: Combine the gelatin powder and lime juice in a small bowl, then microwave for 40 seconds.
- In another bowl, mix the rest of the ingredients, add the gelatin mixture, and mix well.
- Chill the pie for at least 8 hours after spreading the cheesecake filling over the crust.
Tips For Making This No-Bake Keto Key Lime Pie
- You can use lemons, but I recommend using limes for the specific key lime pie flavor.
- Use room temperature ingredients so all the ingredients combine smoothly.
- Line the pan with parchment paper so you can release the pie and transfer it to a cutting board for easy slicing.
- I always make this keto key lime pie with cream cheese the day before serving it. This allows the pie enough time to firm up for clean cuts and lets the flavors develop.
- Make sure not to boil the gelatin and lime juice. Boiling gelatin destroys it and can weaken its gelling ability.
- Use a hot knife to cut the cheesecake evenly.
Key Lime Vs. Regular Lime
- If you’ve ever seen a key lime next to an ordinary lime, you’ll notice the difference immediately because limes can be found in many shapes and sizes.
- Key limes are known for their “bouquet” and intense flavor. They are often used to garnish and flavor seafood, add a tangy touch to drinks, and give typically sweet pastries a zesty twist.
- Key limes are harder to find than regular limes, so locating them may require a bit more effort.
How To Choose The Perfect Limes
When you touch the lime, it should feel juicy; do not take it if it seems dry. Wash well so that no wax remains.
When grating the lemon zest, you should know that only the green part is good, the white one is bitter.
How To Store Sugar-free Key Lime Pie
This refreshing no-bake key lime pie can be stored in the refrigerator or in the freezer.
- Fridge: This keto key lime pie will stay fresh when covered and stored in the refrigerator for 4-5 days.
- Freezer: To store the low-carb key lime pie cheesecake in the freezer, wrap it tightly with plastic wrap and place it in the freezer. It can be stored for up to two weeks. When ready to serve, remove the pie from the freezer and let it thaw in the fridge for a few hours before enjoying.

I made this . its delicious.
If you really want to send this recipe into the stratosphere, toast your almond flour in a skillet for 3-4 minutes and use brown sugar (or lakanto brown). It gives it a really nice depth of flavor and makes it taste exactly like graham cracker!
That’s such a fantastic tip! Toasting the almond flour for a few minutes brings out a nutty, rich flavor, and using brown sugar substitute really does give it that classic graham cracker taste. Thank you for sharing- I know others will love this trick too!
This keto key lime pie recipe is one of my new favorites! I wanted to make something for my mom for Mother’s Day and she requested a keto key lime flavored something. She’s had my key lime pound cake before so I wanted to go with a classic. I landed on your key lime pie specifically because it didn’t use keto sweetened condensed milk, and the steps were way more easy and straightforward. With your recipe, I got the most light and airy key lime pie filling I’ve ever made. It was so good and a huge hit with both my mom and dad. My mom is high protein low carb, and this was her favorite Mother’s Day present. Thank you for your attention and care in creating this recipe, Ioana! P.S. I toasted the almond flour and added brown swerve like another reader suggested and oh my goodness, it’s so good too!
Olivia, I can’t tell you how much this means to me. Thank you for such a kind and thoughtful comment. I’m so glad the recipe felt easy and that the filling turned out so light and airy. That’s exactly what I hoped for when creating it. And now I’m seriously craving it with toasted almond flour and brown Swerve in the crust. That sounds absolutely delicious!
