I have an order for a book cake but am wondering if there is a typical size? 8x11 perhaps? I am really excited to make this since I've never done one before. Just want to make sure I get the servings right (75). Thanks!

I have 3 different size book cake pans...anywhere from about 3/4 of a cake mix to a bit over 2 cake mixes. If you are carving from a rectangle, you can make it what ever size you need to get the number of servings.

That 8x11 pan will only serve some 15-20. You will need to make at least 4 of them. You could do that by placing 2 of them side-by-side (actually tight together) and stacking the other 2 on top of those for a 16x11x4 cake. By the time you cut the 'v' out of the center & slope the sides for the book shape it should be just right.

Thanks girls! I plan on stacking 3 books. Excited to make this cake : )

Guess it also depends on the type of book- I feel that a 9x13 works perfect for a text book. I did a 2 stacked book using the 9x13 pans. Check out my photos.
