Instructions: 1. Preheat oven to 400 deg. F. In a 2-quart glass bowl, combine butter and unsweetened chocolate. Heat in microwave oven on High 2 to 2 1/2 minutes, until melted and smooth when stirred. Let cool to lukewarm.

2. Stir in sugar, egg, vanilla, salt, and buttermilk, until thoroughly blended. Mix together flour and baking soda and stir into chocolate mixture just until combined. Stir in chocolate chips.

3. Spoon batter into 12 paper-lined 2 and 1/2 inch muffin cups, filling to top.

4. Bake 15 to 20 minutes, or until a cake tester inserted in center comes out clean. Let muffins cool in pans 5 minutes, then transfer to racks to cool completely.

Serve warm or cool.
