Step#1
Grab your favorite mug from the cupboard. The bigger the better. Add some sugar for to the bottom of the mug. cocoa powder is quite bitter so you may need more sugar than you realize. I go with 2 tablespoons of sugar for 1 tablespoon of cocoa.
Step#2
Then add some unsweetened cocoa powder, 1 tablespoon. Try using a dark chocolate variety for an intense cup.
Step#3
A little splash of milk just to incorporate the dry ingredients, 1-2 tablespoons. I choose whole milk when I have it because it makes the cocoa rich and creamy.
Step#4
Stir together until no lumps remain and the mixture is smooth.
It should be thick and dark.
Step#5
Slowly stir in the remaining milk until incorporated.
Step#6
Pop it in the microwave for a minute then stir to distribute the heat. Place it back in the microwave and cook for another 30 seconds or until the cocoa is nice and hot.
All you need now is a blanket, some marshmallows and a fireplace.
