Mix EQUAL parts unsweetened cocoa powder and sugar together, of course by all means feel free and lower the sugar content if you like, but this was the perfect mixture for me!
Heat 1 cup soy milk in microwave (mine took just over a minute)
Make 2 shots espresso
Mix cocoa/sugar mixture into soy milk, make sure there are no cocoa lumps
Then mix in the espresso
ENJOY!
