Preheat oven to 375 degrees. Grease and flour 2 9X5-inch loaf pans.

In a large bowl, combine flour, baking powder, baking soda, salt, cinnamon, ginger, cloves, ground mustard, and pepper. Stir to mix and set aside.

Using an electric mixer, cream butter and sugar in a large bowl until light and fluffy. One at a time, add eggs and beat well after each addition.

With mixer running on medium-low speed, slowly add molasses. Add coffee and continue to beat on low speed until well blended.

Gradually add flour mixture, mixing just until dry ingredients are moistened. Careful not to overmix.

Pour batter into prepared pans and place in center of oven. Bake for 40 to 45 minutes, or until toothpick inserted in center comes out clean. Let cool 10-15 minutes before removing from pans.
