I have an order for a number 1 cake coming up this weekend and the client wants at least 75 servings....? I'm offering cupcakes to complement the amount of servings since I don't have the full sheet size cake pan...any ideas? I'm thinking to bake 2 cakes in a 13x9 and cut shapes to form the #1 but I'm nervous for the amount of servings :(  Advise Please!   TIA.

make it a two layer-- bake four 9x13s

Thanks! definitely a good option!
