The Nutty Cocoa Ring Donut is a yeast ring donut dipped in Nutella hazelnut spread and topped with crunchy hazelnut pieces and a drizzle of chocolate icing.
While it isn't quite enjoying the same marketing push (maybe due to limited availability), Krispy Kreme has also introduced the new Chocolate Hazelnut Kreme Donut at participating locations. It's a a yeast donut filled with a chocolate hazelnut Kreme, dipped in Nutella and topped with candied hazelnut topping plus a drizzle of chocolate icing as well as white icing.
The price on both limited-time donuts may vary but go for $1.59 in my area.
You can find a list of participating locations that carry the donut on their website here.
