For those embracing a ketogenic lifestyle, the desire for a sweet, creamy treat doesn't have to be a forbidden indulgence. Homemade keto ice cream offers a delightful solution, allowing you to enjoy a satisfying dessert while staying true to your dietary goals. This article explores the world of keto ice cream, focusing on recipes that incorporate eggs for an extra-rich and creamy texture, akin to a frozen custard.
The Magic of Eggs in Keto Ice Cream
Why add eggs to your keto ice cream? The answer lies in the texture. Incorporating egg yolks into your ice cream mixture results in a smoother, creamier final product. This technique, often referred to as "French" style ice cream, creates a richer mouthfeel that elevates the entire dessert experience.
Overcoming the Fear of Tempering Eggs
Tempering eggs is a crucial step in many egg-based ice cream recipes, and while it might seem intimidating, it's quite simple with the right approach. The key is to gently raise the temperature of the eggs to prevent them from scrambling when added to the hot cream mixture.
Here's how to temper eggs effectively:
- Heat your cream, milk (or dairy-free alternative), and sweeteners in a saucepan over medium heat until hot but not simmering.
- In a separate bowl, whisk the egg yolks until smooth.
- Gradually add a small amount (about 1/2 cup to 1 cup) of the hot cream mixture to the beaten egg yolks, whisking constantly to slowly raise the temperature of the eggs.
- Repeat this process, adding another cup of the hot cream mixture, until the egg mixture is warm to the touch.
- Once the eggs are tempered, you can safely add the egg mixture back to the saucepan with the remaining cream mixture.
The Importance of an Ice Cream Machine
While no-churn keto ice cream recipes exist, an ice cream machine is a worthwhile investment for achieving optimal texture. Ice cream machines work by churning the ice cream base as it freezes, incorporating air into the mixture. This process results in a lighter, more scoopable ice cream, preventing it from becoming a solid block of ice.

Basic Keto Vanilla Ice Cream Recipe with Eggs
This recipe provides a foundation for creating your own customized keto ice cream flavors.
Ingredients:
- 1 can (13.5 oz) full-fat coconut milk, refrigerated overnight (or heavy cream)
- 1 cup heavy cream
- 6 egg yolks
- ½ cup powdered Swerve (or other keto-friendly sweetener)
- 1 vanilla bean, split and seeds scraped (or 2 teaspoons vanilla extract)
- Pinch of salt
- 1 tablespoon vegetable glycerin (optional, for softer texture)
Instructions:
- Prepare the Cream Base: In a saucepan, heat the coconut milk (or heavy cream), heavy cream, vanilla bean (and seeds), salt, and half of the Swerve (or sweetener) over medium heat. Stir frequently until the mixture is hot but not simmering (about 5 minutes).
- Temper the Eggs: In a separate bowl, beat the egg yolks and the remaining sweetener with a wire whisk until well combined. Slowly temper the egg yolks by adding about 1 cup of the hot cream mixture to the beaten eggs, whisking constantly. Repeat with another cup of the cream mixture until the eggs are fully tempered.
- Cook the Custard: Return the tempered egg mixture to the saucepan and cook over medium heat, stirring constantly, until the base thickens slightly and coats the back of a spoon (about 5-7 minutes). Be careful not to overheat or boil the mixture.
- Cool the Base: Strain the custard base through a mesh sieve into a bowl. Place the bowl in an ice bath (a larger bowl filled with ice and water) and let it cool completely, stirring occasionally. Alternatively, you can cool the base in the refrigerator overnight.
- Churn the Ice Cream: Once the base is cool, add it to your ice cream machine and churn according to the manufacturer's instructions.
- Freeze: Transfer the churned ice cream to a freezer-safe container and freeze for at least 2-3 hours to allow it to firm up.
Tips for Success
- Sweetener Choice: Powdered Swerve works best to minimize any gritty texture, but granulated Swerve can be used in a pinch. Other keto-friendly sweeteners like erythritol, monk fruit sweetener, or allulose can also be used.
- Dairy-Free Options: For a dairy-free version, use full-fat coconut milk as the base.
- Glycerin: Vegetable glycerin helps to keep the ice cream soft and scoopable. If you don't have glycerin, allow the ice cream to temper at room temperature for about 30 minutes before serving.
- Storage: Store homemade keto ice cream in an airtight, freezer-safe container in the coldest part of your freezer.
Flavor Variations
Once you've mastered the basic vanilla recipe, the possibilities are endless. Here are a few ideas to get you started:
- Mint Chip: Add a teaspoon or two of peppermint extract to the base before churning. Stir in sugar-free chocolate chips after churning.
- Cookie Dough: Add small chunks of keto-friendly cookie dough after the ice cream has finished churning.
- Brownie Dough: Crumble the crust from a keto chocolate cheesecake into small pieces and add it to the ice cream after churning.
- Birthday Cake: Combine vanilla, butter, and almond extracts to create a cake batter flavor. Add sugar-free sprinkles after churning.
- Coffee Caramel: Add coffee extract, or instant coffee, to the base before churning. Swirl in sugar-free caramel sauce after churning.
- Pecan Praline: Add chopped pecans and a sugar-free praline sauce after churning.
- Peanut Butter: Swirl in peanut butter (or other nut butter) after churning.
- Chocolate: Add unsweetened cocoa powder to the base.
Topping Ideas
No bowl of ice cream is complete without toppings! Here are some keto-friendly options:
- Nuts: Add your favorite nuts, such as almonds, walnuts, or pecans.
- Hot Fudge Sauce: Top with low-carb, sugar-free hot fudge sauce.
- Caramel Sauce: Drizzle with sugar-free caramel sauce.
- Sprinkles: Use your favorite sugar-free sprinkles.
- Chocolate Chips: Add sugar-free chocolate chips.
- Fruit: Top with fresh berries, such as strawberries, blueberries, or raspberries (in moderation).
Addressing Concerns about Raw Egg Yolks
Some individuals may be hesitant to use raw egg yolks in ice cream recipes due to food safety concerns. If you prefer to avoid raw yolks, you can purchase pasteurized eggs or gently heat the base until bubbles form around the edge, ensuring that any potential bacteria are eliminated. Alternatively, the double boiler method described in the carnivore ice cream variation below can be used to cook the egg yolks to a safe temperature.
Keto Carnivore Ice Cream Variation
For those following a carnivore diet, a modified version of keto ice cream can be created using animal-based ingredients. This variation often utilizes raw egg yolks (although the recipe below provides an alternative for those who prefer to cook them), heavy cream, and a keto-friendly sweetener like allulose.

Ingredients:
- 4 large egg yolks
- 2 cups heavy cream
- 1/4 cup allulose (or other keto-friendly sweetener)
- 1 teaspoon vanilla extract
- Pinch of sea salt
Instructions:
- Cook the Egg Yolks (Optional): If you prefer to cook the egg yolks, use a double boiler or place a bowl over a pot of simmering water on low heat. Whisk the yolks in the bowl and continue to stir until the mixture thickens (about 5-8 minutes). The mixture is done when it coats the back of a spoon and a thermometer inserted into the yolk mixture registers 160°F. Remove from heat and set aside.
- Whip the Cream: Pour the heavy cream, allulose (if using), salt, and vanilla extract into a stand mixer with the whisk attachment. Blend until soft peaks form. Taste and adjust sweetener if needed.
- Temper the Eggs (if using cooked yolks): If you cooked the egg yolks, temper them by stirring a spoonful of the whipped cream into the egg mixture. Continue to spoon in about 3 more spoonfuls.
- Combine the Mixtures: Place the mixer on low speed and pour in the egg mixture (cooked or raw) to combine.
- Freeze: Pour the mixture into a loaf pan or airtight container and freeze for 3-4 hours for a soft-serve texture or 8 hours or overnight for hard ice cream. Alternatively, you can churn the mixture in an ice cream machine according to the manufacturer's instructions. For Ninja Creami instructions, see below.
Ninja Creami Instructions:
- Pour the ice cream mixture into two Ninja Creami pint containers and freeze for 20-24 hours.
- Remove the container cover and insert it into the base of the Ninja Creami.
- Cover the lid and press the "Ice Cream" button.
- Remove, stir, recover, and press the "Re-spin" button.
- Enjoy immediately. You can also separate individual servings after spinning and place them into a glass container to soften in the microwave if needed.
Store-Bought Keto Ice Cream Options
While homemade keto ice cream is undoubtedly delicious and allows for complete control over ingredients, there are also several store-bought keto ice cream brands available on the market. Brands like Halo Top and Enlightened offer keto-friendly ice cream options in a variety of flavors. However, it's important to carefully review the ingredient list and nutritional information, as some brands may contain ingredients that you prefer to avoid.
