An easy fudge brownie made with cocoa powder. You can use any brand of cocoa powder, but Valrhona makes them extra good.
This batter is adapted from a back-of-the-bag recipe from King Arthur flour. King Arthur makes the brownies in a 9x13 inch pan and uses a baking temperature of 375F. I like my brownies a bit thicker, so I decreased the pan size to a 9 inch square, reduced the temp by 25 degrees and increased the baking time to about 40 minutes. Brownies are done when a meat thermometer inserted registers 212.
