I remember seeing a little blurb about Thomas' English Muffins getting set to roll-out a Limited Edition flavor: Cinnamon Bun. Then, I forgot about them-- until I went grocery shopping the other day. I smelled them before I saw them, then knew I had to have them.
Boasting real cinnamon (I should hope so), but not too sweet-- you won't feel guilty having one for breakfast, or a snack. I tried these, and they are pretty delicious, but not over-powering. Get 'em while you can!
