Why It Works

• Powdered Sweetener: Using powdered instead of granular sweetener prevents a gritty texture in the final chilled dessert. Allulose is particularly effective here as it freezes softer than erythritol.
• Salt Addition: A tiny pinch of fine sea salt enhances the vanilla notes and balances the perceived sweetness of the keto sweeteners.
• Mechanical Aeration: Shaking the heavy cream incorporates air bubbles into the fat structure, mimicking the churning process of an ice cream maker for a lighter mouthfeel.

Common Pitfalls to Avoid

• Warm ingredients: Always use very cold heavy cream. Room temperature cream will not aerate properly when shaken and can turn into butter.
• Over-shaking: Stop shaking once the mixture feels heavy and looks like whipped cream. If you shake for too long past this stage, the cream will separate into butter and buttermilk.
• Granular ingredients: Avoid granular sweeteners, as they will not dissolve in the cold fat and will leave an unpleasant crunch.

Variations

• Mint Chocolate Chip: Use the base recipe, swap the vanilla extract for 1/2 teaspoon peppermint extract, and fold in 2 tablespoons of sugar-free chocolate chips after shaking.
• Coffee: Dissolve 1 teaspoon of instant espresso powder in the vanilla extract before adding it to the cream mixture.
