Pre-heat the oven to 3500 F. Grease and lightly flour a 9"x13" baking pan. Sift flour along with ½ tsp. Cinnamon powder and salt. Using a wooden spatula whisk well. Add brown sugar, oil and coffee day brew and blend well. Remove ¾ cup of the mixture, add chopped nuts and the rest of cinnamon and keep it aside. Stir in the baking powder and baking soda in to the remaining flour - sugar mixture. Blend in the egg and butter milk until the mixture is smooth. Pour into the baking pan and sprinkle the nut evenly over the batter. (this nut mixture prevents the nuts from sinking into the bottom of the pan) bake for about 35 minutes, or until the cake tester comes out clean. Cool
