Cream of coconut is a sweetened version of coconut cream (think of it like the difference between sweetened condensed milk and evaporated milk). Some brands, such as Coco Lopez, come in a can, while others, like Coco Real, come in a squeeze bottle. You should be able to find coconut cream with the cocktail mixers in the liquor section of the grocery store, or at a liquor store such as BevMo!
