Instructions
Preheat oven to 350 degrees. Line two standard size cupcake pans with 18 liners, set aside.
In the bowl of a stand mixer, beat the butter, oil, sugars, vanilla extract and melted chocolate until smooth. With mixing speed on low, add the eggs one at a time until incorporated.
In a medium size mixing bowl, whisk together flour, sifted cocoa powder, salt, and baking soda. With mixing speed on low, gradually add the dry ingredients along with the sour cream (or buttermilk) and the warm water/espresso mixture. Mix just until combined. Allow the batter to rest for 5 minutes.
Divide batter evenly among cups, filling ⅔ of the way full (I like to use a large scoop, a #20). Place in the oven and bake for 17-20 minutes, or until the tops spring back when touched and a cake tester comes out clean. Be careful not to over bake! Allow the cupcakes to cool in the pans for 5 minutes before transferring to a wire rack to cool completely.
Meanwhile, to prepare the frosting, in a large mixing bowl or the bowl of a stand mixer, beat the butter until smooth and creamy, about 3 minutes. Turn mixing speed off, add the salt and the vanilla extract. Turn mixing speed on to low, then gradually add the powdered sugar and cocoa. Beat for 2 minutes, then turn to low and add the cream. Turn the speed up and beat for 2 minutes or until light and fluffy. Spread or pipe on to the cooled cupcakes, garnish with sprinkles, chocolate shavings and the centers of the Ghirardelli Valentine's Impressions.
Notes
Dutch-process or Special Dark cocoa powder can be used in place of unsweetened cocoa powder, or a blend of each.
