Bought a $16 oven thermometer after my cookies kept burning and it turns out my oven runs 40 degrees hot
I could not figure out why my chocolate chip cookies kept coming out with black bottoms while the middles were raw. After about the fifth batch of sadness, I grabbed a cheap oven thermometer at the grocery store for $16 and stuck it on the middle rack. Set the dial to 350, and the thermometer read almost 390 the whole time. So now I just set my oven to 310 and everything bakes even, which feels dumb but works. Does anyone else have an oven that lies about its temp, or is it just mine?
