When I made this, I used 2 tsp vanilla and only 1/4 c water. The batter was very runny, so I poured it all into shallow (1" deep) pan. Then baked at 325 for about 14 minutes, turning after 7 minutes. It came out like a cake. Very spongy. Not at all like a cookie. I suggest smashing a banana and adding it to the batter (and maybe adjust other ingredients so it'll bake ok). If you don't expect a cookie, then have some ice cream and/or a banana on hand to eat with a piece of this cake.
