At our office we all tkae turns baking b-day cake for each other. I made a 3-layer cake with filling and all, its really very rich and a small sliver is quite filling. But there are 35 ppl in our office, granted not all of them will be partaking of the cake (usually a 9X13 cake feeds everyone with leftovers) but this being a 3-layer 9-inch round cake it appears smaller...you get what I'm saying? So, how thin can I slice it without looking stingy? I want it to stretch for everyone... I know it can but I dont want them to get upset about the thin pieces (which will still be huge considering the layers and 2 layers of filling and all...) these kind of things give me panic attacks so I am sitting here in my office about to throw up...
