HELLO
I AM MAKING A 50TH ANNIVERSARY CAKE. BAKED IT TUESDAY.
FROSTED IT WITH BUTTERCREAM ON WEDNESDAY. DECORATED IT ON THURSDAY AND FRIDAY. PARTY IS AT 6:00 SATURDAY. STANDARD YELLOW, CHOCOLATE CAKE INSIDE. AFTER CRUST FORMED CAKE HAVE BEEN COVERED. WILL CAKE BE EDIBLE AND MOIST? DON'T KNOW HOW LONG YOU CAN GO BEFORE CAKE IS NO LONGER EDIBLE. HELP!

It depends on if your cake is scratch or from a box. Box mixes have preservatives that help them stay fresh longer.

Honestly, Tuesday is a little early for me. For a Saturday event I don't bake any earlier than Thursday (unless I bake, then freeze).

good luck.

Here's a safe storage chart for frosted and filled cakes:
