I experimented with a cinnamon variant of my basic scone recipe for a group meeting today and it seemed to go over fairly well. I was again asked for the recipe.
I used just the basic recipe, but substituted these cinnamon chips (Cinnamon Flav-R-Bites from the Baker's Store) for the dried fruit and sprinkled cinnamon/sugar on the top instead of raw sugar.
They were pretty tasty. If you are a fan of cinnamon scones, I highly recommend this approach. Do not attempt with the basic store bought cinnamon chips that are the consistency of chocolate chips - you won't be happy.
