Iced Brown Sugar Oat Milk Shaken Espresso

How to Make a Starbucks-Inspired Iced Brown Sugar Oat Milk Shaken Espresso at Home

I think it’s time I break up with Starbucks.
Not because I don’t love their drinks (believe me, I do)—but because my bank account and my schedule are no longer on board with the habit. After one too many mobile orders and the creeping realization that I was basically funding a new espresso machine with my weekly total, I knew it was time to learn how to make my favorites at home.

First on my list? The Iced Brown Sugar Oat Milk Shaken Espresso.

If you’re hooked on this smooth, slightly sweet, lightly spiced drink like I am, you’re in luck—it’s surprisingly easy to recreate in your own kitchen. No fancy barista badge required.

This refreshing pick-me-up is a perfect blend of bold espresso, warm brown sugar, a hint of cinnamon, and that creamy oat milk finish. It’s cool, energizing, and honestly? It tastes like you’ve got your life together—even if you’re drinking it in pajamas while answering emails.

Why Oat Milk Works So Well in Coffee

Oat milk is a plant-based powerhouse in the coffee world. It’s naturally sweet without being overpowering, and its creamy texture closely mimics dairy milk, which is why it froths beautifully and blends so well in espresso drinks.

Depending on the brand, oat milk can carry subtle notes of oats, a touch of nuttiness, and even a bit of vanilla—making it a versatile base for lattes, cappuccinos, or iced drinks like this one. And bonus: it doesn’t curdle when poured over ice (unlike some other plant milks).

Whether you’re dairy-free, trying to cut costs, or just love the cozy combo of cinnamon and espresso, this homemade version hits all the right notes.

Ingredients:

• 2 shots of espresso (or about 1/4 cup of strong brewed coffee if you don’t have an espresso machine)

• 2 tablespoons brown sugar (light or dark, depending on preference)

• 1/2 teaspoon ground cinnamon

• Ice

• 3/4 cup oat milk (or more to taste)

• Optional: vanilla extract (1/4 teaspoon) for extra flavor

  Instructions:

  1. Prepare the Espresso:

     • Brew two shots of espresso. If you don’t have an espresso machine, you can substitute with strong brewed coffee, but espresso will give it the signature flavor.

  2. Mix the Brown Sugar and Cinnamon:

     • In a shaker (or any container with a lid), combine the brown sugar and cinnamon. If you'd like a hint of extra sweetness, you can add a splash of vanilla extract here too.

  3. Add the Espresso:

     • Pour the freshly brewed espresso (or coffee) into the shaker with the sugar and cinnamon mixture.

  4. Shake it Up:

     • Add a generous amount of ice to the shaker. Seal the lid and shake vigorously for about 10-15 seconds. This will chill the espresso and dissolve the sugar, creating a frothy, iced coffee base.

  5. Pour Over Ice:

     • Fill a glass with ice, and then strain the shaken espresso mixture into the glass.

  6. Add Oat Milk:

     • Pour in the oat milk. You can adjust the amount of oat milk based on how creamy or light you prefer your drink. Stir gently to combine.

  7. Optional Garnish:

     • If you'd like, sprinkle a pinch of cinnamon on top for an extra touch of flavor.

  Enjoy!

  Your homemade Iced Brown Sugar Oat Milk Shaken Espresso is ready to enjoy! It’s a deliciously creamy, sweet, and perfectly spiced drink—just like the one from Starbucks, but made right at home.
