There are so many different single-purpose baking appliances that it's a wonder nobody has sought to consolidate some of them. For instance, if you can have a doughnut maker, a cupcake maker and, I saw today, a brownie maker, all with approximately the same function, why not one programmable bench-top baking clamshell device? You'd just need different inserts for various shapes of cakes and other baked items, and different presets for temperatures and times based on those standard recipes, plus user-defined profiles.

PPS - But you can't sell that as easily at Big W.
