This homemade version of the Starbucks brown sugar oat milk shaken espresso is quick, easy, and tastes nearly identical to the original. With just a few simple ingredients and a mason jar, you can enjoy a coffee shop-quality drink in about 5 minutes.
Use hot espresso to dissolve the brown sugar properly. Shake for a full 45 seconds for the best foam. For a less sweet drink, reduce brown sugar to 1 1/2 tablespoons. Chill the serving glass beforehand for a colder drink. This drink is best enjoyed immediately.
