In a medium saucepan, heat the milk over medium heat until it begins to simmer. Avoid boiling to maintain the milk's flavor and texture.
Once the milk is simmering, add the masala chai tea bags. Reduce the heat and let them steep for 4-5 minutes.
Remove the tea bags, then add the cocoa powder, sugar, cinnamon, and nutmeg to the milk. Whisk continuously until the cocoa is fully dissolved and the mixture is smooth.
Allow the mixture to simmer for another 2-3 minutes, stirring occasionally. Make sure it doesn't boil.
Pour the Masala Chai Hot Chocolate into mugs. If desired, top with whipped cream and sprinkle with a bit more cinnamon or chocolate shavings.
Your Masala Chai Hot Chocolate is ready to warm you up with its unique blend of spicy and sweet flavors.
