We Put Starbucks’ And Dunkin’s Brown Sugar Oat Milk Sips Head-To-Head In A Taste Test

On Jan. 5, Dunkin’ launched a Brown Sugar Oat Iced Latte on its winter menu.

Starbucks also has a brown sugar sip, the Iced Brown Sugar Oatmilk Shaken Espresso, that’s been around since its release in spring 2021.

We tried them both head-to-head to see how they compare.

Ingredients: Starbucks

The Iced Brown Sugar Oatmilk Shaken Espresso is made with Starbucks’ Blonde Espresso, oat milk, Brown Sugar Syrup, and a cinnamon powder topping.

It’s uniquely prepared by a barista hand-shaking espresso and oat milk together for a frothy texture.

Ingredients: Dunkin’

The new Brown Sugar Oat Iced Latte blends Dunkin’s Signature Espresso with oat milk and a sweet Brown Sugar Cookie flavoring to match.

Taste: Starbucks

The first (and really only) thing that hit me was the taste of the espresso.

On sip two, I tasted the cinnamon topping if I searched for it. My third sip was more cinnamon-forward but the espresso was still the dominant flavor.

Taste: Dunkin’

I instantly noticed the Dunkin’ latte tasted much milkier and sweeter than its Starbucks counterpart.

The brown sugar syrup comes through with every sip, and the oat milk and syrup overpower most of the espresso flavor.

Overall
