Combine coconut milk, sweetener, and vanilla extract in medium saucepan. Bring to a simmer over medium-low heat, stirring frequently.
Place egg yolks in a small bowl and whisk together. Temper eggs by slowly adding some of the heated coconut mixture to egg yolks with a ladle while whisking until eggs reach desired temperature.
Once the eggs have been warmed, slowly stream the tempered eggs into the simmering coconut mixture while whisking to combine. Continue to stir and simmer the mixture until it coats the back of a wooden spoon, about 5 minutes.
Strain the mixture into a CREAMi container to remove any scrambled eggs. Let cool in fridge uncovered for about 15 minutes. Remove from refrigerator and cover. Freeze on level surface for about 24 hours
Place the pint container into the outer container of the Ninja CREAMi and lock on lid. Twist and lock into place and then process on "LITE ICE CREAM”. Remove container from machine and check the texture. If texture is not creamy enough, you place the container back in the machine and do a respin.
Notes
20 to 30 drops of NOW liquid monk fruit or SweetLeaf liquid stevia can be used in place of the allulose but the texture will be harder and less creamy. BochaSweet also works well in the recipe. Or, you can use a combination of sweeteners. You can up the sweetener to ⅓ cup if you prefer a sweeter dessert.For a stronger vanilla flavor, you can add another teaspoon of extract or mix in the seeds from one vanilla bean.Increasing the egg yolks to 3 or 4 will result in a less icy texture.This recipe can be made in a pint-sized ice cream maker like the DASH My Pint. Just churn according to ice cream machine manufacturer’s directions.
