Yes, another brownie recipe. I never much liked brownies made with cocoa powder until I discovered that using 1/2 vegetable shortening made a big difference in the texture, resulting in a much fudgier, firmer cocoa brownie. If you leave out or substitute for the butter or the shortening it just won't be right. Feel free to add nuts or chips if you like, they are good without them. My preference is to frost them, with or without nuts. If you use the basic ingedients, however, I think you'll like the resuls.
