Place all the ingredients in a sauce pot and place on the stove over low heat
Gently stir the hot chocolate mixture until all the ingredients are combined and heated to your liking. Pour the hot chocolate into two mugs
Scoop a big spoonful of mashmallow fluff on top of the hot chocolate and sprinkle with cacao powder. Enjoy!
Notes
-I don't give you an exact amount of marshmallow fluff to use. This is because we all like different amounts of marshmallows. For me, I'd probably use half the batch while someone else may only want a small spoonful
