11x15

Yep! The 9x13 is wrong too!

Thank you so much for sharing this!

how many servings is this supposed to be? and also the 9 x 13? does somebody knows? Thank you for the picture :D

I never go by Wilton but don't forget, the cake is not actually as big as the back of a pan., The cake shrinks and also, I don't know if you do or not, but I always trim the edges off.

Thanks for the info cakequeen! I have never trimmed the edges!! That's very interesting! I just don't want to make a mess and my eye to cut things is not soo good. Also, I have never thought about the cake shrinking! How much does it shrink??

Thanks so much for sharing... Whenever I use the wilton pans, I divide it in half. For example, if I get an order for 30 people, I use the Wilton pan that "serves 60".

Thanks cakequeen, I have never trimmed the edges either, why do you do that? Can you frost it easier that way?
