Overall, not a bad recipe, but not what I was expecting. I expect thumbprint cookies to be tiny little bites. The dough in this recipe spread a lot and made much larger, flatter cookies than what I was looking for. Luckily, I had time to prepare another recipe for the event the next day. The flavor was good, although I did not drizzle with the vanilla chips after discovering that the cookies wouldn't work for my needs. But, the size of the finished cookie is not a thumbprint, in my opinion.
