Make sure the coconut milk is very cold before whipping. The colder it is, the more fluffy it will get. I stick it in the freezer for about 30 minutes before using (even though it was in the fridge) to get it to that stiff, almost solid, form. If you use a different brand of eggnog, then make sure to add dates slowly and taste as you add, I can’t account for the sugar content of other brands. This Silk one only has 8 grams of sugar per 1/2 cup, a little more than half of some others I have seen.
Tips to prep ahead: soak cashews.
Baby/toddler food idea: Serve to baby or toddler by omitting the espresso.
