Mix oats, cinnamon mashed banana and a little liquid of your choice (I just did water but any milk would be great).
Microwave for 1 min.
Stir in protein powder of your choice.
Bake in air fryer for 10 mins.
Top with Greek yoghurt, peanut butter (I used powdered PB mixed with a little sweetener) and crumbled walnuts.
And there you go, cake for breakfast!
