There is a range of ovens from Ninja that will help you bake all kinds of cake or bread products. They'll also do some of the more traditional cooking like roasting and broiling too, so you'll only need a single device in your kitchen.
The more recent range of Ninja Foodis has a 'prove' setting that's designed to help bread rise, and using Steam functions you can make a surprisingly moist cake in your multi-cooker.
