How to make your very own Cooker Oven for Baking almost everything

I use pressure cooker for boiling, steaming, cooking and BAKING as well, yes, it works like a charm to me during summer when it is real high temperature around 100 F here in Florida. I bake cake, cookies, bread and more in cooker and the end result is the same as baked in the oven. Just keep few safety in mind such as removing whistle, ring from the cooker, check your cooker before using, mainly the walve and so on.
