• 1/2 cup hot coffee or water

DIRECTIONS

1. In a bowl, combine the flour, sugar, baking soda and salt; set aside. In a microwave-safe bowl, combine the chocolate and butter. Cover and microwave on hight for 1 minute. Stir; cook 30 seconds longer or until melted.
2. In a small mixing bowl, combine the buttermilk, oil and egg. Add to dry ingredients; beat just until combined. Add the chocolate mixture and vanilla. Pour into a greased 8-in. square baking dish.
