I'm making a birthday cake for a party next weekend. Approx 20-25 people. I'd like to do a round tier cake rather than sheet cake. I'm planning on double layer 9" and 6", but I know that is going to be too much. What other pan sizes do you suggest. I don't want the cake to be too wimpy....

My daugher's baby shower was yesterday. I made a 2-layer 10" round. We had about 15 people. I cut them bigger than my standard wedding pieces and I got about 20 pieces out of the cake.

If you're planning generous servings, I think your 9/6 cake sounds ok.
