1. Using a pair of scissors, cut out Baymax’s arms from a large marshmallow. Cut one mini marshmallow in half for Baymax’s legs and stick them onto the bottom of the large marshmallow. Take a mini marshmallow and cut off just a bit of the bottom so it can stick onto the large marshmallow.
2. Dip a toothpick into the melted chocolate and add Baymax’s features. Set aside.
3. Whisk together the cocoa, sugar, salt, and about 2 tablespoons milk in a small saucepan over medium-low heat until cocoa and sugar are dissolved. Whisk in the rest of the milk and heat it over medium heat, whisking occasionally, until it’s hot.
4. Place Baymax on top of the hot cocoa and serve immediately.
