Question: how much does 12 inch cake feed?
Answer: 12 inch cakes can be very generously served to 40 people with each slice measuring about 1 inch across the back. A standard fork is about one inch wide. Keep in mind that the thinner slice of a 12 inch cake is 6 inches long and 4 or 5 inches tall. Of course a large thin slice of cake can be unwieldy.
