......1/4 sheet that feeds 48 people is a mighty small piece of cake, something like 1" by 2" or 1" x 1.5" ........ IMO it is not nearly enough cake. But that's just me. "
.......I agree! Around here, a 1/4 sheet cake serves 25, 1/2 sheet serves 45-50. .......
.......To say 70 servings out of a half, makes me think that a serving is letting each guest walk up and lick the cake........

Oh my Please look again at what I said....I'm talking about **4"** high layer cakes with filling.
A serving is 1x2x4 period! THAT IS THE SAME AMOUNT OF CAKE AS A 2x2x2 cube so called party size serving. Take a piece of styro or wood cut to the two sizes to show customers. A piece of paper doesn't do it - you don't get the 3-d effect

Regarding the PP/Bettercreme/Rich's: ......"Bettercreme" or "Rich's". It comes frozen in a gallon sized carton. You let it sit 24 hrs in the fridge to defrost. Once it defrosts its like a thick milk. I whip it up in my KA and it turns into frosting.......

Even in my shop I seldom used enough to whip up a full gallon at one time. I *never* defrosted it. Just spoon out what you need and whip it up. That way you don't waste. It whips quick when it is still in it's semi-fzn state And I have fzn left-over whipped now and then - especially if I knew I would be using some like the next week.
