Sift together flour, cocoa, baking powder and salt
Add to creamed mixture
Stir in walnuts
Pour in a greased and floured 8-inch square pan,(can use parchment paper instead if desired)

When cool, you can either dust with confectioners sugar or frost with your favorite frosting, then cut into squares
I've had this recipe for many, many years and have adapted it to my family's liking. These brownies have a nice moist cake-like texture. I've also tried these with the special dark cocoa, good for those who like the dark chocolate flavor.
