There are some recipes at the bottom of this page:

I made this as a single flavor at 10% and it was WAY TOO STRONG. I added 6% Bavarian cream, and it was still pretty strong. Then I cut it with an equal amount of VG (so diluted it to 5% cinnamon coffeecake and 3% Bavarian cream) and it's better. Right now I'm mixing that with some Cinnamon Danish Swirl
juice and I like it, but the CDS recipe has things like sweet cream and cake batter in it as well.
It depends on your tastes, and how much cinnamon you like, but my opinion is use it sparingly, with lots of cream flavors to make it smooth. Sweet cream, custard, Bavarian cream, cake batter, cupcake, and things like that to make it more of a "dessert" flavor and less of a "red-hots" flavor.
