Dunkin' Donuts has released some crazy-sweet coffee flavors in its day — like Fudge Brownie, Vanilla Cupcake, and Cookie Dough — but the chain's newest seasonal flavor couldn't be more perfect for summer. Beginning May 29, s'mores flavor swirls will be available for all of DD's hot and iced coffees, lattes, macchiatos and even the new Frozen Dunkin' Coffee.

We honestly can't believe Dunkin' was able to magically blend together the graham cracker, toasted marshmallow, and rich chocolate flavors into one syrup swirl. But we're ecstatic about it. Especially when we can add it to the Coffee Coolatta's replacement, and see how it stacks up against Starbucks' s'mores frapp (which includes marshmallow whipped cream, chocolate syrup, and a graham cracker crumble on top).

The S'mores swirl joins Coconut Crème Pie and Butter Pecan as Dunkin's summer coffee lineup this year, but there's also an exciting new donuts on the menu as well. Starting May 29, you can find a brand new cake batter donut filled with vanilla cake batter filling, frosted with chocolate icing, and topped with confetti sprinkles.
