You'll need cocoa powder, sugar, milk (any type you prefer), vanilla extract, and chocolate chips or dark chocolate for topping.
Pour milk into a saucepan and warm it over medium heat. Stir occasionally and put the flame down when you can see steam coming out.
Whisk in 2 tablespoons of cocoa powder and 1-2 tablespoons of sugar, depending on how sweet you want.
Add a handful of chocolate chips or pieces of dark chocolate into the saucepan and stir until completely melted, making the hot chocolate thicker and creamier.
Stir in vanilla extract a little for a hint of sweetness and depth of flavor.
Continue whisking until all the ingredients are well combined and smooth, making sure there are no lumps.
Pour your hot chocolate into a mug, top with whipped cream or marshmallows and enjoy the perfect cup of comforting goodness!
