I served the cake with coconut whipped cream that is made by whipping the solid coconut parts from a canned coconut milk. (rodysheartycorner.com)
Remove from heat and add the turmeric and the coconut milk (you can use just the solid coconut part of the can if you like, the more coconut liquid you use, the more watery it will be, that's fine but you just may have to cook it longer to have the coconut milk evaporate) (happygut.ca)
For the creamy coconut part, she uses So Delicious Coconut Milk Beverage. (godairyfree.org)
