This Brown Sugar Oat Milk Shaken Espresso is the perfect way to brighten your morning with a smooth blend of rich espresso, warm brown sugar sweetness, and creamy oat milk. Inspired by a popular Starbucks favorite, this drink hits all the right notes while being easy to make at home in just a few minutes. It’s a delightful caffeinated treat that shakes up your usual coffee routine with a satisfying frothy finish.
I first made this during a busy morning when I craved something special and energizing. It quickly became my go-to pick-me-up, and now friends ask me to make it whenever they visit.
Ingredients
- Two shots espresso: fresh and strong for the perfect coffee punch, choose quality beans for best flavor
- One tablespoon brown sugar cinnamon syrup: adds a cozy warmth and subtle spice, adjust to your sweetness preference
- Four to six ounces oat milk: creamy and dairy-free, it blends effortlessly with espresso, start with half a cup and add more if you like it lighter
- Ice: chills the drink and helps create a frothy texture when shaken
Step-by-Step Instructions
- Brew the Espresso:
- Brew two shots of espresso and pour them directly into a two-cup glass jar. You should have about three ounces total. Freshly brewed espresso is key for a strong and flavorful base.
- Add Brown Sugar Cinnamon Syrup:
- Add one to two tablespoons of brown sugar cinnamon syrup to the espresso. This syrup gives the drink its signature sweet and spiced flavor. Feel free to taste and adjust the amount to suit your sweetness level.
- Fill with Ice and Shake:
- Fill the jar tightly with ice, then close it with the lid. Shake vigorously for 15 to 20 seconds until the mixture is well combined and frothy. This shaking creates a smooth, velvety texture you won’t find in typical iced coffee.
- Add the Oat Milk and Stir:
- Carefully pour four to six ounces of oat milk over the shaken espresso mixture. I usually go with about half a cup but customize it depending on how creamy you like your drink. Give it a gentle stir to combine.
- Sip and Enjoy:
- Take a moment to appreciate the frothy, sweet, and lightly spiced espresso blend. Sip slowly and let it awaken your senses.

My favorite ingredient is the brown sugar cinnamon syrup because it adds a comforting depth that lifts the espresso. I remember making this for a chilly morning gathering with friends and watching everyone’s eyes light up after their first sip.
Storage Tips
Keep leftover syrup in a sealed jar in the fridge for up to two weeks. Before using it again give it a good shake as ingredients may settle. The espresso drink itself is best enjoyed immediately since the foam and fresh flavor diminish over time.
Ingredient Substitutions
If you don’t have oat milk on hand try almond milk or any creamy plant-based milk you prefer. You can replace the brown sugar cinnamon syrup with simple syrup or honey but the cinnamon adds a lovely warmth you won’t want to skip.

Serving Suggestions
Serve this shaken espresso in a clear glass to showcase the frothy top and swirling layers. Garnish with a light dusting of cinnamon for an extra touch of flavor and aroma.
