If we're sharing recipes... I just put some sugar, cocoa, and a bit of salt in a cup, mix it with water to fill the mug about 1/3, microwave about 20 seconds, add light soy milk (that's what I"m currently using) to fill the mug and finish heating about 1 1/2 minutes. Too easy, too tasty. I like the light soy a lot better than the regular. I really should remember to use the CO in coffee and skip the hot cocoa most days. Having the oil float on top hasn't really bothered me but I will try what'd you call it? emulsifying? it. Thanks for starting this thread.
I should never overestimate my basic arithmetic skills.
