With the mixer on low speed slowly add the wet ingredients to the dry ingredients. Continue mixing the ingredients on low adding the coffee,
Make sure that all of the ingredients are blended and include anything stuck to the bottom of the bowl.
Pour the batter into the two pans . Bake at 350 degrees for 30-40 minutes. (Or until a inserted toothpick comes out clean)
