Today I made my carrot cake that I have made for years. Sometimes the cake sinks in the middle and maybe someone can help me with this. I thought maybe it was beating it too long and the eggs caused it to rise too high and then sink. I even have tried room temp eggs. I have tried also when cake is done turning off the oven and leaving it open about 12 in" for about 15 mins. before removing. Sometimes it sinks and sometimes it is perfect and I am so puzzled.
