Refrigerate the coconut milk for at least 24 hours before making this vegan vanilla bean ice cream recipe. Also, make sure your ice cream maker bowl is in the freezer. (See notes.)
Using a stand mixer, whip the aquafaba on high for about 5 to 7 minutes or until it's fluffy and comes to stiff peaks.
In another bowl, combine the coconut milk (both solid and liquid parts), vanilla bean paste, coconut sugar, and sea salt.
Fold the coconut milk mixture into the whipped aquafaba until combined. Do not over-stir so it does not lose its fluffiness.
Pour the mixture into the ice cream maker and prepare according to the manufacturer's instructions.
Once thick, you can immediately eat your vegan vanilla ice cream or spoon it into a freezer-safe container, cover it tightly, and freeze.
Remove the vegan ice cream from the freezer for 10 to 15 minutes before serving for the perfect scoopable consistency.
