I use mixes for my cakes. It is just easier for me. I have to do a 1/2 sheet cake, and I am wondering how many mixes to use. When I make a regular 9X13 I use 1.5 cake mixes so it's a bit bigger and not so thin. So, for a 1/2 sheet should I use 3? 4?

Any help is greatly appreciated!

I just made a half sheet cake last week...12x16...I used 2 cake mixes.

My 1/2 sheet pan calls for 2 boxes I have the 11x15 size.

I use 2 1/2 for chocolate and at least 3 if using white. sometime add the extender to the white for taller cake.

I use 3 1/2 for 12x18 (large 1/2 sheet). I use 1 1/2 for 9x13. You need to measure your batter everytime because recipes are different.

I agree with turtleshell.ALWAYS measure.Also look here.

Thanks everyone for your replies! It seems as thought everyone has a different way, which makes me feel better - then I'm not feeling weird for doing something different from someone else.

Me again!

I have a pan that's 11X18. How many servings will I be able to get out of that? An approximate is fine, I'm just curious.

The cake I'm making is going to a nursing home for the staff.

I use the 12x18 for my half sheet and use 4 boxes.
