So I do all that but...
Use Drostese cocoa powder
Up the cocoa to two heaping regular ol' crereal type eattin' spoons.
down the sugar to about 1/2 table spoon (you'll see why at the end)
add it all to the milk that is heating in a pan and whisk it til hot, but don't burn the mutha fuckin' milk, foo.
THEN! pour into your cup and add- CREME DE MENTH
and top with all the marshmallow fluff yer mug will hold.
(see, both creme de menth and fluff have a lot of sugar in them already)
I come to you, defenses down, with the trust of a child.
