Mix everything except milk into a large oversized mug. Microwave milk for about 1 1/2 minutes. Pour hot milk immediately over pumpkin chocolate mixture and stir until everything is dissolved into the milk.
You may need to put it back in the microwave for an additional 30 seconds and stir again to make sure everything is completely melted. Alternatively, you can mix everything over low to medium heat in a small sauce pan on the stove until everything is mixed and dissolved. Serve immediately.
