I had a cake go nuclear inside my oven once. It was a new recipe that I had never tried and I used the size of pan that the recipe called for...but obviously it must have been a misprint...it made a major mess. Thank goodness it was in the oven in the garage and I was able to turn the oven up to broil and burn the heck out of it and it just flaked off the oven floor. I was pi$$ed!!!
