Isn't it just easier to eat chocolate - and much more pleasurable!
Adding cocoa to soap is waste of good cocoa if you ask me.
In the quantities I tend to eat it, I do.
You can use cocoa to make chocolate cake. I'd rather have chocolate cake than a cake of soap .
You'd make rather a mess trying to shower with a chocolate cake!
I bet I could eat a chocolate cake in the shower without a single drop of water falling on it. For chocolate, I'd even dislocate my jaw like a snake to shovel it all in!
