Dunkin Donuts Late Summer 2025. The breakfast chain’s new coffee drink flavors include a blueberry donut iced coffee, vanilla frosted. Dunkin’s summer menu arrives on june 26th, 2025 and will be available until august 27th.

I predict lemonade products will come back, as well as raspberry watermelon refreshers. Dunkin’ has rolled out a series of colorful new menu items that are perfect for the summer season, including a cup that everyone will want their hands on.
