The flavors are bakery shop-themed and come in five varieties: Blueberry Muffin, Caramel Coffee Cake, Chocolate Glazed Donut, Jelly Donut, and Old Fashioned Donut.
The coffee come pre-ground in 12-ounce bags with a price tag in the $7 to $9 range.
Personally, it sounds more like "Donut Shop Series" than anything, but I guess calling it "Bakery Series" leaves more room for new flavors down the line.
If you're looking to find them, Dunkin' has an product finder online to help you out.
