Cocoa brownies have the softest center and chewiest candylike top "crust" of all because all of the fat in the recipe (except for a small amount of cocoa butter in the cocoa) is butter, and all of the sugar is granulated sugar rather than the finely milled sugar used in chocolate. Use the best cocoa you know for these fabulous brownies.
Chocolate note:
Any unsweetened natural or Dutch-process cocoa powder works well here. Natural cocoa produces brownies with more flavor complexity and lots of tart, fruity notes. I think it's more exciting. Dutch-process cocoa results in a darker brownie with a mellower, old-fashioned chocolate pudding flavor, pleasantly reminiscent of childhood.
