                            | 1. Butter two 9-inch round cake pans; line bottoms with parchment paper or waxed paper. 2. Position a rack in the middle of the oven; preheat to 350°.
 3. Melt chocolate in a large heatproof bowl set over hot, but not simmering water; let cool.
 4. In a bowl, stir the flour, baking soda, and salt together; mix well.
 5. Add the butter to the chocolate, then pour in the boiling water; stir well to mix.
 6. Whisk in the sugar and sour cream.
 7. Stir in the flour mixture; whisk in the eggs.
 8. Pour the batter into the prepared pans; smooth the tops.
 9. Bake for about 25-30 minutes or until test done—toothpick comes out clean.
