A quick and simple recipe to make a creamy, sweet, and frothy iced espresso drink at home using brown sugar and oat milk, inspired by Starbucks.
Use room-temperature espresso to help dissolve sugar better. Shake vigorously for 15-20 seconds to create frothy texture. Barista-style oat milk froths better but regular oat milk works fine. You can substitute espresso with strong brewed coffee or cold brew concentrate. Adjust sweetness by reducing brown sugar or using alternative sweeteners like maple syrup or monk fruit. Prepare espresso ahead and refrigerate but shake only before serving.
