Keto key lime pie recipe FAQs
Are there any ingredient substitution options?
- Butter: Coconut oil can be substituted in for butter in both the crust and filling at a 1:1 ratio.
- Classic Monk Fruit Sweetener: Lakanto Golden Monk Fruit Sweetener, erythritol, or Swerve subbed in at a 1:1 ratio will work here. Powdered or liquid stevia will not work.
- Cream Cheese: Mascarpone cheese can be substituted in for cream cheese. Instead of 3/4 cup of cream cheese, I would use 1/2 cup mascarpone. Note that this substitution will alter the final nutrition information.
- Powdered Monk Fruit Sweetener: If you don’t have powdered monk fruit sweetener on-hand, simply pulse granulated monk fruit sweetener in a high-speed blender or food processor until powdered.
- Key Lime Zest and Key Lime Juice: The zest and juice from regular limes will work just fine here!
Where can I purchase monk fruit sweetener to make this recipe?
Monk fruit sweetener is now widely available at most grocery stores, especially specialty food stores and Costco. I personally purchase mine online from Lakanto and have it directly shipped to me.

How is this recipe nut-free if there is coconut in it?
This recipe uses shredded coconut, but coconuts are not actually nuts. They’re a fruit (a drupe).
Real Balanced recipes are nut-free, but they DO contain coconut products.
Here’s what the American Academy of Allergy, Asthma, and Immunology has to say about nut allergies and consuming coconut:
“Although the Food and Drug Administration labels coconut as a tree nut, the vast majority of tree nut-allergic individuals also tolerate coconut without difficulty, since coconut is not truly a nut, but rather a fruit.”

Of course, please check with your doctor if you have any questions or concerns. If you are looking for recipes that are both nut-free and coconut-free, you can try these keto coconut-free recipes.
Why are there avocados in this dessert recipe?
The filling for this Keto Key Lime Pie is made from a combination of avocado and mascarpone cheese.
If you’ve never had avocados in a dessert before, you may be a little unsure of what to expect in a final product; rest assured, the resulting pie is sweetened and you won’t notice that avocado was used. Plus, using avocado gives you an extra dose of healthy fats!
How many net carbs per serving?
Each slice contains 3.6 grams of net carbs.
This recipe yields 10 servings in total. One slice is equivalent to one serving.
How to store this pie?
Refrigerator Storage: Store in an airtight container in the refrigerator for up to 3 days.
Freezer Storage: Store in an airtight container in the freezer for up to 2 months. I would recommend freezing it without the whipped cream topping. Thaw pie completely in the refrigerator prior to serving.
How to make this keto and nut-free key lime pie
Preheat oven to 300 degrees. Liberally coat bottom and sides of 9-inch springform pan with nonstick cooking spray.

Transfer pan to oven to bake until edges are golden brown, about 20-25 minutes, before removing pan from oven and allowing to cool.
Filling: Meanwhile, to a mixing bowl, add all filling ingredients.
Blend all filling ingredients together using an electric mixer or high-speed blender. Taste mixture and add additional powdered monk fruit sweetener based on sweetness and tartness preference.
Spoon filling atop cooled baked crust. Transfer pan to freezer to freeze until set, about 1-2 hours, depending on the temperature of the freezer.
Topping: Meanwhile, in a mixing bowl, using an electric mixer, mix together heavy cream and powdered monk fruit sweetener until whipped. Transfer prepared whipped cream to the refrigerator to chill until pie is ready to serve.
Final Steps: Once set, remove pie from freezer and allow to sit at room temperature to soften slightly before topping individual pieces with prepared whipped cream and fresh lime zest.
