Preheat skillet or griddle. In a large bowl, whisk together the flour, hot chocolate mix, baking powder, baking soda, and salt.
Add the egg, milk, vegetable oil, and peppermint extract. Whisk until just combined.
Fold in the chocolate chips. Grease skillet or griddle with nonstick cooking spray or butter and pour batter onto the hot surface.
Cook until the pancake begins to bubble, then flip to cook the other side. Continue until all batter has been used.
Serve with mini chocolate chips, mini marshmallows, whipped cream, crushed peppermint candy, and chocolate syrup (optional).
