How do you make your hot chocolate milk?

I make hot cocoa. I use a microwavable glass mug, and I put about 1/4 cup of water in the bottom, and microwave it for 1 minute. Then I add a heaping teaspoonful of cocoa power and a heaping teaspoonful of sweetener, and stir well. When the cocoa and sweetener have formed a loose paste, I add milk to the mug, stir well again, and then microwave for 2 minutes.
