[Fullmetal Alchemist] How far does Alchemy go? Can I bake a cake just by zapping the ingredients?

Can I zap hop and water and get beer?  
EDIT: By the way, guys: IT'S MAGIC!!! I don't care what anyone says.

Theoretically yes, but food is incredibly complex compared to rocks and metals. To use alchemy you have completely understand the molecular structure of the thing you're transmuting, so it would probably take decades to get skilled enough, organic/biological alchemy is the most challenging field of alchemic study by far.
