You might like to try (current-message).

For some reason, (window-buffer (minibuffer-window)) returns the " *Minibuf-0*"
buffer rather than the " *Echo Area 0*" buffer.

This should work. At least in my tests:
M-: (progn (message "foob") (with-current-buffer " *Echo Area 0*"
(message "%S" (buffer-size)))) RET
returns 4.
