While I enjoy the flavor of a good frosting, I find that it can often overwhelm a cupcake, especially with cupcake bakeries pushing the trend towards really piling it on. Once there is more frosting than cake, it's time to cut back. As a result, I often opt for glazing cupcakes with chocolate or a powdered sugar glaze to make things simpler and maintain a good cake-to-frosting ratio. Another option is to just use a simple dusting of powdered sugar. Sprinkles don't really adhere to this type of cupcake topping, but by using a stencil, cut out of a stiff piece of cardstock or other thick paper, you can easily dress them up.
For this design, I used a simple line design and dusted the cupcakes with a mixture of cocoa powder and cinnamon, but anything that will create a color contrast will work well. If you are going to use a sticker buttercream-type frosting, you can use colored sugars with the stencil to make designs that way, but it's best to keep the frosting level and not pile it on to ensure a clear pattern.
