# Expert Advice:

01 -
  • It's smoother and creamier than your usual iced coffee because the shaking aerates everything into silk.
  • The brown sugar syrup is forgiving—you can adjust sweetness on the fly and even experiment with other sugars.
  • Completely vegan and dairy-free, but tastes indulgent enough that nobody notices the trade-off.
02 -
  • The brown sugar syrup thickens as it cools, so if you make it ahead, you might need to warm it slightly before using—this was a frustrating discovery I made on my third attempt.
  • Shaking is non-negotiable; stirring will not give you that frothy, aerated texture that makes this drink different from just mixing cold coffee and milk together.
03 -
  • Chill your shaker for five minutes in the freezer before shaking if you want an even colder drink—this sounds obsessive but actually works.
  • If you don't have a cocktail shaker, a mason jar with a tight-fitting lid works perfectly, and honestly, it looks better on the counter anyway.
