So, accidentally, our toaster oven was on toast/grill.
I baked cookies in it not realising until one tray was done.
Those cookies turned out great. Soft and chewing but also crunchy.
On realising I had just the grill on and not the oven, I changed it. The oven baked cookies were a bit dry. I might grill all cookies from now on.
I think it might only work in a toaster oven because it still gets pretty warm all over with just the one element on but I am going to remember for next time, for sure.
