Can hot chocolate get any better? Yes.¹
Tip: This also works for milkshakes.
Make a mug of your preferred brand of hot chocolate.
Use milk (even if non-dairy open_in_new), coffee, or water, depending on your taste.
Stir in a touch of vanilla extract open_in_new.
That's where the magic is.
Similarly magical alternatives include chili powder, mint, cinnamon, etc.
