                                According to Dunkin's official information, a standard, unflavored latte is made with just espresso and milk, and therefore contains only the naturally occurring lactose sugar from the milk. The answer to whether a Dunkin' latte has sugar in it depends entirely on whether you add extra sweeteners, like a flavor swirl, or order a pre-sweetened Signature Latte.
