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.

If you want to order your monk fruit sweetener online, you can use discount code REALBALANCED for 20% OFF your order!

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 to store this pie?

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.

Crust: In a food processor, pulse sesame seeds and shredded coconut until ground.

Transfer mixture to mixing bowl and add melted butter, monk fruit sweetener, and salt. Using a spoon, mix all ingredients until well-combined.

Spoon crust mixture into a prepared springform pan and, using your fingers, press mixture into even layer across base and up sides of pan to form crust.

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.
