Preparation

Step 1

Preheat oven to 350. Line muffin cups with paper liners.
1. Put the unsweetened chocolate into a bowl set over gently simmering water and stir occasionally til melted. Set aside to cool.
2. In a small bowl, whisk the flour, baking soda and salt.
3. In a mixing bowl, beat the butter 30 to 60 seconds or til smooth. With mixer running, gradually pour in the sugar, scraping the sides and bottom of the bowl a few times. Then beat in medium high til light and fluffy, 2 to 3 minutes.
4. Beat in the eggs, one at a time, beating well after each addition, scraping the bowl after each addition.
5. Beat in the vanilla and melted chocolate til smooth and blended.
6. On low speed, add the dry ingredients in 3 installments, alternating with the espresso in 2 additions.
7. Stir in the chocolate chips by hand.
8. Divide the batter evenly among the prepared muffin cups. Don't smooth the batter.
9. Bake the cupcakes til they spring back when gently pressed in the center, 20 to 22 minutes.( a little longer if making jumbo cupcakes). Let them cool 5 minutes in the pan, then remove and cool on a wire rack before frosting.
Frosting:
1. Put the chocolate and butter in a bowl over gently simmering water and stir til melted and smooth. Set aside to cool til barely warm.
2. In a medium bowl, whisk together sour cream, vanilla and salt.Gradually whisk in the confectioners' sugar til smooth.
3. Add the chocolate/butter mixture and beat it in with the whisk til smooth and creamy.
The frosting must be thick and spreadable. If too thick, thin it with a few droplets of milk. If too thin, chill it briefly, stirring occasionally, til adequately thickened.
