This copycat Iced Brown Sugar Oat Milk Shaken Espresso tastes better than Starbucks, and it's so easy to make at home! It uses homemade brown sugar syrup, and the shaken espresso has just a few simple ingredients and comes together in less than 5 minutes!
Syrup - Check out my post for Brown Sugar Simple Syrup with more info and tips. Store the syrup in an airtight jar in the fridge for up to 2 weeks or in a freezer-safe container in the freezer for 2-4 months. If you don't want ground cinnamon in your coffee, add a cinnamon stick when simmering the syrup. The syrup makes about 12 servings (2 tbsp per serving).
Starbucks cup sizes - Different Starbucks cup sizes have different amounts of coffee and syrup. Their shaken espresso pumps of syrup are half pumps. The regular pump is about ½ tbsp. I find the Starbucks syrup sweeter because it uses regular cane sugar along with brown sugar, and this recipe only has brown sugar, so I use more of it.
Here are the exact Starbucks measurements:
