Volume of cake batter for one cake?
I will be buying a new stand mixer soon. I want to know the volume of batter it takes to make at least 2 cakes, preferably 3 or ideally 4 :) (each to be 13x9"). For reference, the choco cake that I usually make requires 2 cups of sugar, 3 cups of flour, 2 eggs, 1 cup of oil, 2 cups of water, half cup of cocoa powder and a few teaspoons of this and that.
I don't have my mixer now (am in transit) or else I would whip up a cake quickly - there is always a need for good, moist chocolate cake ;) - and just measure the volume myself.
Can someone give me a ball park figure here?
