Add the cold brew or iced coffee to a glass along with the Irish cream syrup. Use a spoon and stir to combine.

To make the cold foam, add the milk and vanilla syrup to a glass. Use an electric frother and whip until the milk has turned into a thick foam. If you don't have a frother, add the ingreients to a mason jar, seal, then shake until thick and foamy.

Add ice to your glass, if desired, then slowly pour on the vanilla cold foam. Add a dash of cocoa and enjoy immediately.
