Purely an experiment with cinnamon oil, these swirlybirds are not quite ready for prime time. Senior White Chocolate Taste Tester Mom agrees. At least I've got the look down. To make the filling, I mixed my own redi-fondant with cinnamon oil and some red oil-based candy colors from Wilton. The pink-looking stripe, is not flavored, but colored white chocolate. Next time, I'm flavoring the stripe as well and wrapping the candy in red foil.
