Melt and let cool the unsweetened chocolate.
In a mixing bowl, whisk together the flour, soda and salt.
In another mixing bowl, combine buttermilk and vanilla.
Preheat oven to 350 degrees.
Line a 12 cup muffin pan with paper liners or grease and flour the muffin pan.
In a large mixing bowl, (preferably a stand mixer bowl) beat butter until creamy.
Gradually add and beat on high speed, brown sugar. It will be light in color and texture - about 4-5 minutes.
Beat in egg.
Beat in chocolate until just blended.
Add the flour mixture, alternating with the buttermilk - start and end with the flour mixture.
Beat on low speed until smooth; scrap sides of the bowl as necessary.
Stir in chocolate chips.
Scoop the batter into the muffin cups and place in the oven.
Bake for 25-30 minutes or until a toothpick inserted in center comes out clean.
Let cool for 2-3 minutes before removing to cool completely on wire rack.
Serve and enjoy!
