Chill your tools. Place the ice cream maker bowl in the freezer for at least 24 hours if required by your machine. Chill a mixing bowl in the fridge for 30 minutes to help the base stay cold.
Blend the base. In the chilled bowl, whisk together coconut milk, coconut cream, powdered erythritol or allulose, vanilla, coconut extract (if using), salt, and alcohol (if using). Whisk until the sweetener fully dissolves and the mixture is smooth.
Taste and adjust. Taste the base.
If you want it sweeter, add 2–3 drops of stevia and whisk again. Remember that cold mutes sweetness slightly, so aim for just a touch sweeter than you’d like the final ice cream.
Chill thoroughly. Cover and refrigerate the base for at least 2 hours, or up to overnight. A colder base churns faster and gets creamier.
Churn. Pour the cold base into your ice cream maker and churn according to the manufacturer’s instructions, usually 18–25 minutes, until it reaches a soft-serve consistency.
Add mix-ins. In the last minute of churning, sprinkle in the shredded coconut if you’re using it.
This keeps it evenly distributed.
Firm up. Transfer the soft ice cream to a lidded, freezer-safe container. Press parchment paper directly onto the surface to prevent ice crystals. Freeze 2–4 hours for scoopable firmness.
Serve. Let the container sit at room temperature for 5–10 minutes before scooping.
Use a warm scoop for smooth, round scoops.
