The only sprinkley things I like on a donut are chocolate sprinkles or coconut. My favorites though are regular donuts with chocolate icing. There used to be a donut shop here in town that made a German Chocolate donut - boy was that wonderful!!
I love donuts, but I hardly ever eat them. My favorite is Krispy Kreme glazed. Once upon a time I went to a Krispy Kreme store where they actually make the donuts and I got a glazed donut right off the warm rack. It was heaven.
