I would never think to pair coffee and butterscotch together, but I recently found a recipe for some sticky coffee and walnut puddings which combined these flavours, and I thought I would try them out in cupcake form. I was surprised to discover that they go very well together and the sweetness of the butterscotch complements the bitterness of coffee nicely. Which I guess makes sense, as I do enjoy a caramel latte from time to time!
