Did you use a toaster oven. It is quite common with a toaster oven to do this. They have to have the broiler element on to reach temperature, meaning it will try to broil your bread instead of bake it.

BTW welcome to our forum.

Quick question, if you were making a cake, did you use one box or two boxes if you used two boxes and the receptacle you used was narrow and deep the cake will take double the time written on the cake box. If you used one box and again used a narrow and deep pan it takes much longer than the time on the box, the wider 3" deep pans works much better

Sounds to me like someone used the broiler on an electric oven, lol. The heat came from the top and not the bottom.
