Here is an example, courtesy of the website Delish. This site offers examples of 12 quirky foods that have bacon as an ingredient. One of them is a bacon lollipop. Check out item #4: the owners of a bake shop in Boulder, Colo., so loved the taste of the Vosges bacon-chocolate bar that they developed the bacon-maple-chocolate cupcake.
I like each of those flavors, but I'm slightly skeptical as to whether they would make for a marvelous harmony or not. (I like mustard and butterscotch, but I'd never combine the two flavors.) But even I have to admit, it looks tasty.
By the way, Vosges has more than one chocolate treat containing bacon.
