I was trying to find a gooey cholatey brownie which would be good for me and still conqueer my cravings. This will fulfill all your requests, and beyond. If you like it sweet you might want to add 1/4 cup artificial sweetener or 1/2 cup sugar but i do not as i want to dark, bittery cocoa taste. The baking time will differ to your personal oven, i am sorry if it will not be as gooey ooey as expected when you try it the first time. I recomend you keep watching the batter, when you can see the edges hardening up it is ready. Note: I did changes since i got such a bad rating. It is much better now :-)
- Mix yogurt and cacao.

- Stir inn rice flour.
- Spread the batter into prepared pan (3' x 5').
