How many people will a 11 x 18 cake feed? I have to feed 65 girl scouts & their dads. Will that be big enough? Should I make it a 2 layer?

Wilton's chart shows a 12x18 double layer cake serving 98. That's wedding size servings. If you need 65 servings for scouts, and 65 dads, that's 130 servings.

12x18 (called a half sheet by many here) single layer will serve 54 (2x2x2) pieces.

A two layer 12x18 half sheet will serve 108 (1x2x4) pieces.

To serve girls and dads, I'd probably make a 2 layer 12x18 cake.

If cake is the only dessert than, yes I think you need more even if its double layer. If its a banquet and there will be cookies, brownies etc. I think you will be ok with the 2 layer that size. You can look up serving charts for any size pan here on cake central or just google it

Standard serving size for a 2" high cake: 2"x2"x2"

Volume of a standard serving: 8

Volume of a 12"x18"x2" cake: 432

432/8 = 54 servings


Standard serving of a 4" high cake: 1"x2"x4"

Volume of a standard serving: 8

Volume of a 12"x18"x4" cake: 864

864/8 = 108 servings

Here is a thread with some good info on how to determine servings on sheet cakes ("Do the math"), plus a link on the history of sheet cake sizes and why the 12x18 is considered a half sheet: http://cakecentral.com/cake-decorating-ftopict-670996-math.html
