Dark Chocolate Whole-Wheat Brownies

whole-wheat flour ((I tested this recipe with King Arthur’s organic white whole-wheat flour, which is 100% whole-grain))

unsweetened cocoa powder (you will have much better results if you use “dark” cocoa (Hershey’s makes some))

baking powder

coconut oil

pure maple syrup (or honey - my family is divided because I loved the maple version and they loved the honey version)

pure vanilla extract

egg

nuts (chopped (optional))
