Q: Why do most of my cakes dome in the centre, no matter what type of cake they are?
A: The most common reason cakes dome in the centre is that the oven is running hot. If the recipe requires the oven to be at 180 degrees, try dropping it to 170 degrees the next time you make a cake. You may have to bake it for slightly longer than you usually do (about 5 minutes). If the cake doesn’t dome (or dome as much as usual) at this new adjusted temperature, it is a good sign that your oven is generally running hot. If so, it would be worth adjusting the baking temperature for all future bakes or get your oven calibrated by a technician so you don’t have to worry about it in the future.
