There is a Safeway Grocery in West Sedona that makes sheet cakes and special orders and a very expensive cake shop with wonderful designs. The name is Cake Couture and I'm pretty sure you can look at their website. A new chocolate shop has opened in Cottonwood, about 16 miles from Sedona that is looking to cater to occasions and events at several of the area wineries. Sorry I don't know their name, but I hear their chocolate is wonderful. I think if you could check with one of the area wedding planners here, they also could be a good resource for you.
