I am making a "gift" cake-- square cakes of the same size stacked on top of each other, to make one giant square. I need 30 servings. I have magic line pans, and my squares are 6 inch, 8 inch, and 10 inch... Could I get away with using the 8 inch to make the cake?? Or would it not be enough servings?

I'm not 100% sure that I know what you mean, but a 2-layer 8X8 serves 32. That's probably not going to give you the height you want though. A 2-layer 6X6 serves 18. If you stacked 4 6X6 layers, it would give you 36 servings.

Does any of that help?

I think you could probably do it if you cut wedding size slices. Wilton's chart says an 8" square pan will yield 32 wedding size slices.

You could always do a 6" and and 8". That would give you bigger slices and plenty of cake.

Goodluck and hope this helps!

How many layers are you going to do?

If you do two 2in layers of the 8in square (8x4 in cake) you will have 32 1x1.5 servings.

If you do four 2 in layers of the 8in square (8x8 in cake) you will double the servings, so you will have a total of 64.

I think I'll go with two 3-inch 8x8's stacked! Thanks!!
