Creamy Vanilla Keto Ice Cream (No-Churn Option)
This rich, velvety low-carb dessert skips the icy texture common in many sugar-free ice creams by creating a homemade, sugar-free condensed milk base. It delivers a deeply satisfying, classic vanilla flavor with a perfectly scoopable consistency.

- Yield3 cups 1x
Ingredients
Scale
Cold Dairy Mixture
- 1 cup unsweetened almond milk (or unsweetened coconut milk beverage)
- 1 cup heavy cream
- 2 tsp vanilla extract
Condensed Cream Base
- 2 cups heavy cream
- 1/3 cup powdered monk fruit allulose blend
- 3 tbsp unsalted butter
- 1/8 tsp fine sea salt
Instructions
- Prepare the cold mixture: In a medium bowl, whisk together the almond milk, 1 cup of heavy cream, and vanilla extract until evenly combined. Cover and place in the refrigerator to keep cold.
- Melt the butter: In a large, wide skillet (avoid deep saucepans to maximize evaporation surface), melt the unsalted butter over medium heat for about 1 to 2 minutes, until it is fully liquid and gently bubbling.
- Reduce the cream base: Pour the remaining 2 cups of heavy cream into the skillet, followed by the powdered sweetener and fine sea salt. Bring to a gentle boil, then immediately reduce to medium-low heat. Simmer for 30 to 45 minutes, stirring occasionally. You will know it is ready when it smells rich and sweet, the volume has reduced by half, and it thickly coats the back of a spoon—swiping your finger across the spoon should leave a clear, holdable line.
- Combine and chill: Transfer the hot, condensed cream to a large, heat-proof bowl and let it sit until cooled to room temperature. Once cool, whisk in your refrigerated cold dairy mixture until completely smooth. Cover the bowl tightly and refrigerate for at least 4 hours (or overnight) until completely cold to the touch.
- Churn the ice cream: Pour the thoroughly chilled mixture into your ice cream maker. Churn according to the manufacturer’s instructions for about 20 to 25 minutes. It is finished churning when it reaches the thick, creamy consistency of soft serve.
- Freeze to set: Enjoy immediately as soft serve, or transfer the mixture to a 9×5-inch freezer-safe loaf pan. Smooth the surface with a spatula and press a piece of parchment paper directly onto the ice cream to prevent ice crystals from forming. Freeze for 2 to 4 hours, until firm enough to scoop.
Notes
Why It Works
- Reducing the cream and butter on the stovetop creates a concentrated base that mimics traditional sweetened condensed milk, lowering the water content to yield a supremely creamy, velvety mouthfeel.
- Using an allulose-based sweetener is key here, as it resists freezing rock-solid, keeping your low-carb ice cream much softer and more scoopable than if you used pure erythritol.
Common Pitfalls to Avoid
- Using a narrow pot: If you simmer the cream in a standard saucepan instead of a wide skillet, the reduction process will take significantly longer due to the smaller surface area.
- Skipping the chill time: The base must be colder than 40°F before churning. If it is too warm, the ice cream maker will struggle to freeze it quickly, resulting in an unpleasantly greasy texture.
Variations
- No-Churn Alternative: If you do not have an ice cream maker, pour the chilled base into a loaf pan and freeze. Vigorously stir the mixture every 30 minutes for the first 2 hours, then every 60 to 90 minutes for the following 2 to 3 hours to break up ice crystals as it sets.
- Chocolate Chip: Slowly sprinkle in ½ cup of sugar-free dark chocolate chips during the final 2 minutes of churning.
