You could do it with a macro, something like:

a=getTitle(); // your stack
for(i=1;i<=nSlices;i++){
 setSlice(i);
 run("FFT");
 selectImage(a);
}
run("Images to Stack", "name=Stack title=[FFT of] use");

You might have to change the FFT options to get only the real part, but I
think that real and imaginary parts are returned as a 2 slice stack, so there
might be more modifications to do to the above.
