PCB considerations - Sigma ADAU1452

I'm starting to play with the ADAU1452 eval board.  While contemplating my end product, I'm curious about some of the requirements. My first question is, and I apologize if this is too freshman, is it possible to use a double sided board with the 1452 chip or is a 4 layer the only way to go?  I recognize that the main pad under the chip will be necessary which I think will eat up both the top and bottom layers of a double sided board.  The question in my mind is if the necessary PS decoupling caps can be placed close enough without using the sandwiched layers.
