I typically avoid sugar but I love whipped cream . Is this a thing? The question is pretty straightforward. Thanks so much!
First, know that sugar is not a required ingredient when whipping cream. It will come together fine without adding anything to the cream.
As to coconut milk, it typically has a fat content around 25% (compared to about 35% for whipping cream.) While it's possible 25% is enough to work, all the recipes I found skim off the water, resulting in an even higher fat content – likely 50%+ given the amount of water in a typical can of coconut milk.
So this is quite possible to do; personally I would try finding (or creating) a recipe that kept some or all of the liquid in, just in the interest of health and possibly making the resulting product a bit less heavy.
(Note this would definitely be something I would want to enjoy in moderation, given the extremely high amounts of saturated fat present in coconut milk.)
