Butter a 9"x9" baking pan & preheat oven to 350F. Cream butter. Cream sugar and red pepper into butter. Beat in eggs and vanilla(*). Sift together flour, cocoa, cinnamon and salt and fold into creamed mixture until evenly mixed.
Spread evenly in buttered pan and top with walnuts as desired (I do 4 corners of nutted and un-nutted for thems who don't like nuts and nutted to keep thems who don't like nuts off my half).
Bake for 35-40 minutes. Cool/serve.
