They're $1.59 each in my area but I received this courtesy of Krispy Kreme.
The bits of hazelnuts add a nice, almost grainy crunch and extra dose of nuttiness.
Unfortunately, the donut itself was a bit stale and dry. Krispy Kreme's signature donut is known for its cloud-like quality when fresh, so it was doubly disappointing. I tried heating it up for a few seconds in the microwave but it ended up chewier and oily.
