This keto ice cream recipe has gone through several iterations. I’ve tested it at least a dozen times! You might have seen an older version of it back in 2017, but I’m renewing this post in 2019 to reflect my improvements.
After this much (delicious) testing, I can confidently say that this is the BEST low carb ice cream recipe out there! At least the best keto vanilla ice cream, for sure.
Aside from keto cheesecake, the number one keto dessert that people ask me for is how to make keto ice cream. And while there are a million ice cream flavors that you could make (like keto hazelnut ice cream in my Easy Keto Cookbook!), my first priority when making homemade low carb ice cream was just a basic sugar-free ice cream recipe.
The key part to this easy keto ice cream is the sugar-free sweetened condensed milk.
Is Ice Cream Keto?
No, most ice creams are not keto friendly. There are a few keto ice cream brands out there, but it’s much cheaper to make your own and this way you know exactly what’s in it. Don’t worry, it’s much easier than you think.
Can You Make Low Carb Ice Cream Without An Ice Cream Maker?
Yes! You can make my homemade low carb ice cream recipe without an ice cream maker if you don’t have one.
But, you can also use an ice cream maker if you do have one. I’ll show you how to make keto ice cream both ways!

- Calories 347 kcal
- Prep Time 5 minutes
- Cook Time 30 minutes
- Total Time 5 hours 35 minutes
- Servings 8 servings
- US Customary – Metric
- 3 tbsp Butter
- 3 cups Heavy cream (divided into 2c and 1c – see notes)
- 1/3 cup Powdered allulose
- 1 tsp Vanilla extract
- 1/4 cup MCT Oil (or MCT oil powder; one of these is highly recommended if not using an ice cream maker)
- 1 medium Vanilla bean (optional; seeds scraped)
How To Make Low Carb Ice Cream (For BOTH Methods – No Churn or Ice Cream Maker)
- Melt the butter in a large saucepan over medium heat. Add 2/3 of the heavy cream (2 cups (473 mL)) and powdered sweetener. Bring to a boil, then reduce to a simmer. Simmer for 30-45 minutes, stirring occasionally, until the mixture is thick, coats the back of a spoon and volume is reduced by half. It will also pull away from the pan as you tilt it. (This will go faster if you use a larger pan.)
- Pour into a large bowl and allow to cool to room temperature. Stir in the vanilla extract, and seeds from the vanilla bean, if using. Whisk in the MCT oil or MCT oil powder if using – this is highly recommended in general, and a must if you don’t have an ice cream maker.
- Whisk the remaining 1 cup heavy cream into the sweet mixture in the bowl, until smooth.
How To Make Keto Ice Cream With An Ice Cream Maker
- Transfer the mixture to your ice cream maker and churn according to manufacturer’s instructions, until the ice cream is the consistency of soft serve. (My ice cream maker took 15-20 minutes.)
- Enjoy immediately, or transfer to a freezer container and freeze for 2-4 hours, until firm.
How To Make Keto Ice Cream Without An Ice Cream Maker
- Transfer the mixture to a freezer container (like a 9×5 in (23×13 cm) loaf pan) and smooth the top with a spatula. (If you want to add mix-ins, gently stir them in at this step, and also sprinkle some on top.) Line the surface with a piece of parchment or wax paper to keep ice crystals from forming. (You can use an ice cream maker if you have one.)
- Freeze for 5-6 hours, until firm. Stir the ice cream during the freezing process, every 30 minutes for the first 2 hours and every 60-90 minutes for 2-3 hours after. (Ice cream will get hard in the freezer after longer periods. Let it soften on the counter for 10-30 minutes before serving, and use a wet ice cream scoop to serve.)
Serving size: 1/2 cup
- This keto ice cream recipe was updated in June 2018 and again in July 2019 to improve texture. The changes included ingredient amounts and method, but nutrition info has not changed much. Nutrition info below reflects the current sugar-free ice cream recipe shown here, not including optional MCT oil/powder. The video still shows the old method of whipping the cream, which you don’t need to do – just whisk the liquid directly into the condensed milk instead.
- If you’d like to lighten up the sugar-free ice cream a bit, you can replace some of the heavy cream in step 1 with coconut milk or almond milk instead (it may take longer to reduce). However, you don’t want to replace any of the cream in step 4.
- Low carb ice cream does harden if it’s in the freezer too long. Using MCT oil or MCT oil powder in the recipe helps.
- After more than 6-8 hours in the freezer, you will likely need to soften the sugar-free ice cream on the counter before serving.
