Combine the melted butter and sugar in a mixing bowl. Blend well until smooth. Add the salt, vanilla, coffee, and cinnamon, and blend until smooth. Add the eggs, 1 at a time, and mix until smooth. Combine the cocoa powder and flour, and sift. Add the cocoa-flour mixture to the butter mixture and to form a batter. Add 1/2 of the nuts and blend well.

Grease a 9 by 13-inch baking dish. Pour the batter into the dish. Sprinkle the surface with the remaining 1/2-cup of nuts. Bake for 35 to 45 minutes.
