TIP NUMBER 1
Try Freezing Your Cake!
Not only does this allow you to start baking early,
but it also makes the cake moist,
alot easier to frost, and it will hold up better.
I try to bake my cakes the week before I want to decorate them. If I don't get around to it I will usually make them Monday or Tuesday of that week. For Example: If we are serving the birthday cake on Saturday, I will make the cake on Monday or Tuesday. I will take it out Thursday and begin the decorating process. If you don't have the time, try to at least freeze it for 24 hours. Trust me you won't be disappointed.
Bake your cake and let cool completely
Wrap in 2-3 layers of saran wrap
Wrap in 2-3 layers of aluminum foil
Place in freezer
I stack like sizes on top of eachother. If you place smaller sizes onto larger ones you will get a dip in the middle of your larger cake.
