Start by brewing a strong cup of dark roast coffee using your preferred method; set aside.
In a small saucepan, gently heat the milk over low heat until it begins to steam, about 2 minutes.
Add a drop of peppermint extract or finely crushed peppermint candies to the warm milk. Stir gently with a whisk or spoon until the candies melt or the extract is fragrant, about 2-3 minutes.
Pour the brewed coffee into your favorite mug, filling it about three-quarters full.
Slowly add the peppermint-infused milk to the coffee, allowing the creamy white to swirl into the dark brew, creating a beautiful marbled effect.
Stir in cocoa powder and a sweetener if desired, blending well until fully incorporated and the drink is smooth.
Top the drink with a generous dollop of whipped cream and garnish with a tiny candy cane for a festive touch.
Enjoy your cozy peppermint mocha while it’s warm, fragrant, and visually inviting.
