Adjust the Kahlua to your sweetness preference. The sweetness level between different versions may vary widely. I use a homemade Kahlua made by our wonderful family friends!
**I prefer making this cocktail with the Whole Foods 365 Brand Coconut Milk. I don't recommend the Thai Kitchen brand or the Chaokoh brand - both have an aftertaste and Thai Kitchen is quite watery.
The store-bought brand Kahlua is not technically vegan because it uses a non-vegan process in refining sugar. If this does not bother you, the classic version is otherwise vegan and does not contain milk.
