Since it was founded in 1950 by Christian Merino, Dunkin' Donuts has become one of the largest coffee and baked goods chains in the world. Boasting more than 12,000 restaurants in 36 countries, it's hard not to recognize their signature storefront sign.

As of 2013, there were about 7,677 Dunkin Donuts retail locations across the United States, it's no wonder America Runs on Dunkin'!

This summer, the famous donut shop has a new, limited-time promotion that will fuel your sweet tooth and inspire you to sing Kumbayah by the fire.

Find out which fabulous flavors are coming to your Dunkin Donuts locations this summer!

Summer just wouldn't be the same without an ooey gooey s'mores sandwich. If you're not much into campfires and Kumbayah, no worries - you can still enjoy the taste of s'mores without taking a bugspray bath.

If you still love the taste of melted chocolate, graham crackers and marshmallow, then you'll be excited to know that Dunkin' is offering a brand new s'mores donut starting July 3.

It's for a limited time only, so hurry up and get your hands on this toasted-marshmallow filled donut topped with Hershey's chocolate and of course graham cracker crumbles!

On the same day, July 3, Dunkin's also introducing the Chocolate Drizzled Strawberry Croissant Donut. The name is a mouthful but don't let that stop you from taking a big bite of this delicious pastry.

PopSugar describes it as the donut version of a chocolate-covered strawberry and you'll be inclined to agree! Bite into layers of flaky, buttery croissant donut filled with sweet strawberry jelly and drizzled with chocolate icing.

Both are available for a limited time, so don't miss out! Which would you try?
