'Perfectly Chocolate' Chocolate Cake and Frosting

Cake: Preheat oven to 350 degrees and spray two 9 inch round baking pans with non stick cooking spray. Combine first 6 dry ingredients in a large mixing bowl. Add eggs, milk, oil, and vanilla and beat on medium speed for 2 minutes. Stir in the hot coffee and mix well with a spoon (batter will be thin). Pour batter into pans and bake for 30-35 minutes or until wooden toothpick inserted into the center comes out clean. Cool 10 minutes and then remove from pans to wire racks. Cool completely before frosting. Frosting: Melt the butter and stir in the cocoa. Alternately add powdered sugar and milk, beating on medium speed to spreading consistancy. Add more milk, if needed. Stir in vanilla.
