Will my 4 1/2 quart Kitchenaid handle 2 boxes of the WASC?
Thanks,

If you mean the full recipe - starting with 2 boxes - mine just barely made it. It worked, but it was really, really full

2 boxes of cake mixes with the WASC ingredients, or two full recipes?

I think it would be a stretch and you would probably have a very full mixer, if it didn't overfill if you did the two boxes of stuff plus all the other stuff.

I use the extender recipes, which is basically like the WASC just divided where you use one cake mix and half of the stuff called for. (One cup flour, one cup sugar, one cup yogurt/sour cream.....)

I have 4-1/2 qt. too and mine was definitely overfull. It kept trying to slosh out. I was much better off either halving the recipe or using my huge pyrex bowl and handmixer.

Huge bowl and hand mixer it is. I need 2 full recipes for a 1/2 sheet cake. Thanks for the help.

A 12x18 takes 14 cups of batter.

If you are using the following recipe...

You would know need one of them to fill the 12x18. Do you have two pans that you plan on baking at the same time? If not and you plan to do two layers I would just mix up one recipe, bake that and then do it again.

I am using 2-12x18 to make a single layer sheet cake for a graduation. I have one already done but borrowed my mom's kitchenaide hoping it would all fit. Not much fun. Oh, well.

Whenever I make a WASC sheet cake with 2 layers, I halve the recipe, make the batter, pour it into a larger bowl, make another batch, pour the second batch into the bowl with the first batch and stir to combine both batters. While you should not have to do this if you duplicate both batches, I have have duplicate batches taste slightly differently. So, I take this extra step before pouring the batter into the pans to avoid this problem.

I bought the 5qt glass bowl to fit my KA45 just so I could mix the entire WASC recipie at one time. It's still full, but it works and was sooooo worth the investment!

Great idea. Hadn't thought about that!
