1In a saucepan, whisk together cocoa powder, sugar, and cornstarch until well combined.
2Pour in a small amount of milk and stir until you get a smooth, clump-free paste.
3Gradually add the remaining milk, stirring continuously to blend everything smoothly.
4Place the saucepan over medium heat and bring the mixture to a gentle simmer, stirring constantly.
5Continue to heat until the mixture thickens to a creamy, smooth consistency. Remove from heat as soon as it starts simmering to obtain a creamy hot chocolate.
6Once thickened, remove from heat, pour into a mug, and enjoy your rich Italian hot chocolate!
