Add the almond milk, coffee or espresso, chocolate syrup, peppermint syrup, half-and-half if using, vanilla, and a small pinch of salt to a small saucepan.
Heat over medium-low heat until hot, but do not boil.
Whisk well, or use a handheld milk frother, until everything is combined and slightly foamy.
Taste and adjust the chocolate, peppermint, or sweetener as desired. Pour into a large mug. Top with whipped cream, a drizzle of chocolate syrup, and a little crushed peppermint if desired. Serve immediately.
