This is what you call a Malfunctioning oven.
Oven is set to 400
thermometer inside tells me its 350.
So the other day I decided to make Chocolate Zucchini bread. Well it seemed like it was cooking however after 45 min the inside was NOT cooked at all so I put it back in and after 10 min it over flows everwhere. So I tried a cake same problem. We finally got a thermometer and sure enough my oven is malfunctioning.
