Will you pay me Tuesday for a cake I bake today (Read details)?

Tuesday is my birthday (yes, penguins do celebrate birthdays) and I will be having some company. Today is my best day for baking the cake but I am wondering if it will still be fresh enough (or still in existence) if I bake it today. It will be a layer cake with frosting. One possibility is to bake the layers today and wrap them in cellophane, then frost tomorrow afternoon.
