I'v just tried it ! Very good, especially if you like dark chocolate, and full of good fat, but the taste of olive oil is a little bit strong, I'll try it with coconut oil next time. Very good when refrigerate. 1750 calories for the whole cake (Yes it seems huge, but it is only very good ingredients and you can make like 7 small slices, which is equivalent to 250 calories per slice) .
I've made this healthier chocolate-chip cookie recipe about a hundred times now, and not one single person can tell the difference between these and the cookies that are loaded with fat and sugar!
