In a medium saucepan, combine water and sugar over medium heat and stir until the sugar has dissolved.
Whisk in the sifted cocoa powder and salt until combined and there are no lumps. Remove from heat.
Stir in vanilla extract and peppermint extract.
Let cool completely and store in an airtight, food-safe container like a mason jar.
Peppermint Mocha
In a small saucepan over medium heat, warm the milk. Stir until it begins to simmer.
Add hot espresso and chocolate mint simple syrup to a mug. Stir together.
Add the warm milk over top.
Garnish with whipped cream and candy cane pieces, if desired.
Notes
Be sure to sift the cocoa powder to avoid lumps in the syrup.If you don’t have time to make the chocolate syrup, you’re not out of luck. When you warm the milk, stir in 3 tablespoons of sugar and 1 tablespoon of unsweetened cocoa powder. Then add ¼ teaspoon peppermint extract.
