Great tip about separating and freezing the biscuits.
My original house wall mounted oven stopped working a number of years ago. It isn't as easy to replace as just taking it out and putting in a new one, it's dimensions are different, the cabinet is different, it is hard wired, yada yada yada -- best way to replace is to do an entire kitchen remodel and that hasn't happened.
But -- toaster oven! Wow, it isn't the way to make lots of sheets of cookies, but it is amazing what you can fit into one. It's light weight and easy to move -- so in this super hot weather, I just took it out on the porch and do my cooking outside.
