This easy Starbucks copycat iced brown sugar cinnamon oat milk latte is creamy, cozy, and dairy-free. Make a coffee shop treat at home in under 10 minutes—no fancy equipment required!
For best results, use barista-style oat milk and double-strength coffee if not using espresso. Make the syrup ahead for quick assembly. Use coffee ice cubes to prevent watering down. Adjust sweetness and spice to taste. For a hot version, skip the ice and use steamed oat milk.
