Dark Chocolate Cupcakes with Peanut Butter Frosting (again)

These are some rich cupcakes.  They are a bit much for me, so I don't usually eat them; I just bake them for others.  Although, now that I think about it, I bet they go really well with a strong cup of black coffee. 


The cupcake recipe makes two dozen cupcakes, while the frosting makes about three cups.  I always forget that it's not quite enough frosting to do just one batch!  Or maybe I'm just heavy-handed with the frosting?  I can't help it,  it's good stuff!

Enjoy the recipe, it's an easy one, and I think the frosting is the best part!

Dark Chocolate Cupcakes 
from America's Test Kitchen

16 tablespoons (2 sticks) unsalted butter, cut into 16 pieces
4 ounces bittersweet chocolate, chopped
1 cup Dutch-processed cocoa powder
1 1/2 cups all-purpose flour
1 1/2 teaspoons baking powder
1 teaspoon baking soda
1 teaspoon salt
4 large eggs, room temperature
2 teaspoons vanilla extract
1 1/2 cups sugar
1 cup sour cream

•  Microwave the butter, chocolate, and cocoa powder together, whisking often, until melted and smooth, about one to three minutes.  Let cool until just warm to the touch.
• Adjust an oven rack to the middle position and heat the oven to 350 degrees.  Line two muffin pans with cupcake liners.  Whisk the flour, baking powder, baking soda, and salt together in a large bowl.
• Whisk the eggs and vanilla together in a large bowl.  Slowly whisk the sugar until combined.  Whisk in the chocolate mixture.
• Sift 1/3 of the flour mixture over the batter, then whisk.  Whisk in the sour cream.  Sift the remaining flour mixture over the batter and whisk completely.  The batter will be thick!
• fill the cupcake liners about 2/3 full.  Bake about 18 to 22 minutes, or until a toothpick comes out with a few crumbs attached.  Rotate the pans halfway through baking.
• Let the cupcakes cool in the pans for five minutes.  Remove from the pans and let cool completely before frosting.

Peanut Butter Frosting
from America's Test Kitchen

2 tablespoons heavy cream
1 teaspoon vanilla extract
Pinch salt
2 sticks unsalted butter, softened
1 1/2 cups confectioner's sugar
1 cup creamy peanut butter (do not use old-fashioned or natural peanut butter)

Stir the cream, vanilla, and salt together until the salt dissolves.  Beat the butter with an electric mixer on medium-high until smooth, about 30 to 60 seconds.  Reduce the speed to medium-low, slowly add the confectioner's sugar and beat until smooth, about two to five minutes.  Beat in the cream mixture.  Increase the speed to medium-high and beat until the mixture is light and fluffy, about four to eight minutes.  Beat one cup creamy peanut butter and sugar mixture.
