Peanut Butter Topped Devils Food Cupcakes
For the cake
1 1/3 cups all-purpose flour
1/2 cup unsweetened cocoa powder
3/4 tsp baking soda
1/2 tsp baking powder
1/4 tsp salt
1 1/4 sticks (10 tablespoons) unsalted butter, at room temperature
1/2 cup (packed) light brown sugar
1/2 cup sugar
3 large eggs, at room temperature
1 tsp pure vanilla extract
2 ounces bittersweet chocolate, melted and cooled
1/2 cup buttermilk or whole milk, at room temperature
1/2 cup boiling water
4 ounces semisweet or milk chocolate, finely chopped, or 2/3 cup store-bought mini chocolate chipsGETTING READY: Center a rack in the oven and preheat the oven to 350 degrees F. Butter two 8-x-2-inch round cake pans, dust the insides with flour, tap out the excess and line the bottoms with parchment or wax paper. Put the pans on a baking sheet.
TO MAKE THE CUPCAKES:
Butter and Flour two cupcake pans. Set aside.
Sift together the flour, cocoa, baking soda, baking powder and salt.
Working with a stand mixer, preferably fitted with a paddle attachment, or with a hand mixer in a large bowl, beat the butter on medium speed until soft and creamy. Add the sugars and continue to beat for another 3 minutes. Add the eggs one by one, beating for 1 minute after each addition. Beat in the vanilla; don’t be concerned if the mixture looks curdled. Reduce the mixer speed to low and mix in the melted chocolate. When it is fully incorporated, add the dry ingredients alternately with the buttermilk, adding the dry ingredients in 3 additions and the milk in 2 (begin and end with the dry ingredients); scrape down the sides of the bowl as needed and mix only until the ingredients disappear into the batter. At this point, the batter will be thick, like frosting. Still working on low speed, mix in the boiling water, which will thin the batter considerably. Switch to a rubber spatula, scrape down the bowl and stir in the chopped chocolate. Divide the batter evenly between the two pans and smooth the tops with the rubber spatula.
Bake for 20 minutes, rotating the pans at the midway point. When fully baked, the cakes will be springy to the touch and a thin knife inserted into the centers will come out clean. Don’t worry if the tops have a few small cracks. Transfer the cupcake pans to a rack and cool for about 5 minutes, then run a knife around the sides of the cakes, unmold them and peel off the paper liners. Invert and cool to room temperature right side up. (The cooled cake layers can be wrapped airtight and stored at room temperature overnight or frozen for up to 2 months.)

1 cup creamy peanut butter
5 tablespoons unsalted butter, at room temperature
1 teaspoon pure vanilla extract
1/4 teaspoon kosher salt
1/3 cup heavy creamPlace the confectioners’ sugar, peanut butter, butter, vanilla, and salt in the bowl of an electric mixer fitted with a paddle attachment. Mix on medium-low speed until creamy, scraping down the bowl with a rubber spatula as you work. Add the cream and beat on high speed until the mixture is light and smooth. Frost cupcakes and use any left over frosting to make graham cracker sandwiches. Yum!
