Here’s my excellent microwave cocoa- a scant teaspoon sugar (the less sugar you use the more chocolatey it will taste), 1/2 teaspoon Ceylon cinnamon, 1 heaping tablespoon cocoa powder and about half an inch of skim milk in the bottom of your mug. I microwave on high for 30 seconds and then whisk like mad to incorporate the cocoa, stream in milk to fill the cup while continuing to whisk. Microwave on high another 2 minutes. I don’t drink coffee or black tea so this is my usual starter in the morning. If you are using a different cinnamon you probably only want 1/4 teaspoon as it will be much stronger.
