I know you're supposed to put cake batter in the oven as soon as you are done mixing it, but I only have a 5qt KA, and a 12x18 sheet cake calls for soooooo much batter. What kind of mixer do you use so you can make all this batter at once and fill a sheet cake? Oh,and I make my cakes from scratch, so I know that probably doesn't help my situation but I could really use advice because I run into this a lot when people want sheet cakes or even the 10" rounds. Please help. THX!!!!!

12x18 needs 14 cups of batter

there's 4 cups to a quart (2 cups = 1 pint; 2 pints = 1 quart)

so that's 3 and 1/2 quarts of batter.


so more than enough room in your 5 qt. mixer

And no, you don't have to put batter in the oven as soon as you mix it. It will sit just fine on the counter for a little bit if you have to spend 3-4 minutes mixing a 2nd batch.

Doug, when I used a 5 qt, I could only get 2 cake mixes in there and the 12x18 uses 3 mixes. Which worked out ok for me, actually, coz all of my sheets are half white and half choc, so I'd have to let the batter sit while I mixed up the other flavor anyway.
