You will still find yourself missing a slice when you go to put it together.

Bowls can dry without cracking, as they are essentially a series of outside perimeters, stacked on one another, and not a perimeter fighting a center.

Could the cookies be cut in quarters and then rejoined when dry IE with dowels/biscuits and glue?

What you can try is taking 3 slabs, and cutting them into quarters and drying them. Make the middle one a sacrificial one, that you use to cut out the chunks you need to fill the gaps in the other two. Because the middle slice was cut next to the ones you want to rebuild the grain will be close to matching.

What happens is that as wood dries it shrinks more in different dimensions. The circumference will shrink more than the radius. Maybe 10% for the circ, 5% for the radius. Exact amounts vary with the species, but it's usually more than the wood can handle 

So as Jeff suggests, you end up with a piece of pizza missing from the pie. But if you want to go down the path of gluing the pie back together, you could. You just need to borrow some extra slices from another pie.  :D

It would also be an interesting geometry excercise to make it back just like it looked when you started.
