How to Make Keto No-Bake Key Lime Cheesecake {Quick Overview}

This is just a quick overview of some of the steps involved in making the low carb dessert. For the recipe in detail, including exact measurements used at each step, scroll to the recipe card at the end of the post.

First, you’ll make the crust.

TIP: The crust needs to chill in the fridge for one hour before the filling is added. After the crust has chilled for 45 minutes, feel free to get started on the filling steps!

Next, you’ll make the filling, starting by whipping the whipping cream until stiff peaks form. Place the whipped cream in the fridge.

In another bowl, mix cream cheese and Swerve Confectioners. Then add key lime juice, vanilla extract, and sour cream and thoroughly mix.

Remove the whipped cream from the fridge and gently fold it into the cream cheese mixture, being sure not to overmix.

Remove the crust from the fridge, add filling, and refrigerate!

After the cheesecake has firmed up in the fridge for at least 8-12 hours (I like to aim for 14 if possible), slice, serve, and enjoy.

Optionally garnish with Keto Whipped Cream, lime zest, and/or lime wedges.

Crust Ingredients

  • 1 1/4 cups almond meal or almond flour
  • 1/2 cup Swerve Brown or other brown sugar substitute
  • 6 tbsp melted butter

Filling Ingredients

Optional Toppings


Crust Instructions

  • Combine almond meal (or flour) and Swerve Brown in a bowl, then add melted butter and combine thoroughly.
  • Press the crust very tightly into the bottom and up the sides of a 9” pie dish. Use a measuring cup or the back of a spoon to pack the crust firmly.
  • Chill for one hour in the fridge.

Filling Instructions

  • Add heavy whipping cream to a mixing bowl and beat with a hand or stand mixer on high speed, scraping down the sides as needed, until the cream forms stiff peaks (approx. 2-4 minutes). Once done, refrigerate it.
  • In another mixing bowl, blend cream cheese and Swerve Confectioners on medium speed, scraping down the sides as necessary, until the mixture is smooth.
  • Add key lime juice, vanilla extract, and sour cream, and mix on medium speed until smooth, remembering to scrape down the sides when needed.
  • Take the chilled heavy whipping cream from the refrigerator and gently fold it into the cream cheese mixture using a silicone spatula. Avoid overmixing to prevent the whipped cream from deflating.
  • Remove the crust from the fridge and pour the filling onto it, spreading it evenly with a silicone spatula or an offset spatula. (Use an offset spatula if you have one!)
  • Cover the mixture and refrigerate for a minimum of 8-12 hours, or longer if possible (I typically aim for 14 hours).

Serving Instructions

  • Take the cheesecake out of the fridge and slice using a knife. For neater cuts, heat a jar of water in the microwave, dip the knife in the water, and wipe it off before each cut. The warmed knife will result in cleaner slices.
  • Keep covered in the refrigerator for a maximum of five days.
  • To serve, top with Keto Whipped Cream and optionally lime wedges and lime zest.
