Used in 444 soy. Has a fairly substantial hot throw (not the strongest but good), and definitely a yummy scent. To me, the sweet "icing" scent was far prevalent over the cinnamon, though it definitely has that deeper spicy cinnamon note to it. Some people will be more sensitive to the cinnamon, so I would say it's a good choice for fall/holidays.
I got 4oz bottles of Cinnamon Buns, Gingerbread, Hansel & Gretel's House, and Creme Brule, and I have to say they are all so similar that I can hardly tell the difference between them in a finished candle, with Creme Brule being the most different. If I were trying to come up with a selection of food scents for a candle line, I might only pick one of these four to include. They all have slightly different notes, but after a while you realize they all have a very similar overall tone. I would suggest trying smaller bottles of these to see which has the undertone you prefer, or try mixing them with other scents that compliment their specific undertones to bring out a wider variety of custom scents.
