Ok i thought that my oven would be a little off. So yesterday i happened to find an oven thermometer at a thrift store in its original packeging (cardboard thing with plastic covering front with staples). Today i tested it, i heated my oven up to 300 degrees and i looked in the oven without opening the door and it said 373 degrees! I was shocked, my baked goods never come out over done or anything, they usually are very blond on the top and bottom. I don't know if i should just keep doing what i have been doing or to trust the thermometer! Please help me, i have to make a birthday cake in a few days!
