Coconut cream consists of coconut meat and a small amount of water, whereas cream of coconut is coconut cream that's been sweetened and processed to achieve a thick, syrup-like consistency.

It's available at most large supermarkets, typically found in the section with cocktail mixers and other drink ingredients. You might also find it in the international foods aisle, particularly in the Latin or Caribbean products section.
