Iced brown sugar oat milk espresso

Ready for one of the more interesting espresso drinks to come your way? Iced Brown Sugar Oat Milk Espresso. Just the ring of it sounds like a certain ultra popular coffeeshop, and you’re right! It’s a Starbucks invention. Here’s the thing: the Starbucks version of this shaken espresso tastes just okay. The homemade version? It tastes great. It’s deliciously nuanced, cozy, and just sweet enough, cinnamon forward with a warm nuance from the brown sugar syrup. Really, you’ve gotta try this!

What’s an iced brown sugar oat milk espresso?

The iced brown sugar oat milk espresso is a Starbucks drink that combines shaken espresso, oat milk, and brown sugar syrup. It’s essentially an iced latte, but the espresso is shaken for a frothy texture and it has slightly less milk. The Starbucks version of this drink says it uses brown sugar syrup to add a hint of warmth, but in our opinion it’s difficult to detect in the flavor. This homemade version brings all the flavor notes in strong! Here’s what you’ll need:

  • Espresso
  • Brown sugar syrup: made in 5 minutes with brown sugar!
  • Cinnamon
  • Oat milk: best quality

Make an iced brown sugar oat milk espresso…better than Starbucks

The iced brown sugar oat milk espresso at Starbucks tastes overwhelmingly like oat milk: it’s pretty one note flavor-wise. When we ordered it, we had big expectations! But you get none of those brown sugar or cinnamon flavor notes. (In fact, the whole drink just made me thirsty.) Making it homemade makes one incredible drink: you’ll get dark espresso notes, cozy brown sugar, spicy cinnamon, and creamy oat milk all in one sip. Here are the basic steps:

  • Step 1: Make the brown sugar syrup.
  • Step 2: Make a double shot of espresso.
  • Step 3: Place the espresso in a jar with 1 ½ tablespoons syrup and ⅛ teaspoon cinnamon and shake!
  • Step 4: Add ½ cup regular oat milk and enjoy.

Use high quality oat milk

Another note: make sure to use best quality oat milk: it really affects the flavor! Some oat milks can have an artificial aftertaste: experiment and find one you love. (We enjoy Planet Oat: let us know your favorite brands.)

  1. Add up $4 – $6 per day for coffee shop espresso-based drinks, double that for the two of us. $5 x 2 x 65 = $650 and we’ve paid for our Breville Espresso Express in a tad over two months. Now, tell me again how expensive those espresso machines are? Oh, and we almost always have more than one espresso beverage in a day.
