This Brownie recipe is made with Dark Chocolate and not Cacao Powder. Because most of the flavours (and texture) relies on the chocolate, try to use a good quality Cooking Chocolate when possible - with a high percentage of cacao. I used a 70% cacao Chocolate. Also note that you should only use Cooking Chocolate - and not an eating chocolate bar or chocolate chips. These do not melt or bake as well and can create a grainy texture in your brownies.
