You can as long as you get permission from the copyright owner. Luckily Rovio (the owner of Angry Birds) seems to be more willing to grant licenses than most, but if you are selling the cake you might have to pay a license fee.
We would probably charge in the $800-900 range (plus any license fees) for this cake since it is labor intensive and we rent a commercial kitchen by the hour. A legal home-based bakery might be closer to $600.
OP, you may want to check out two articles I wrote on my blog (links below in my signature), one about pricing and one about copyright.
