ULTIMATE CHOCOLATE CUPCAKE (AMERICA'S TEST KITCHEN) RECIPE - (4/5)

Steps:

• FOR GANACHE FILLING: Place chocolate, cream, and confectioners' sugar in medium microwave-safe bowl. Heat in microwave on high power until mixture is warm to touch, 20 to 30 seconds. Whisk until smooth; transfer bowl to refrigerator and let stand until just chilled, no longer than 30 minutes. FOR CUPCAKES: Adjust oven rack to middle position and heat oven to 350 degrees. Line standard-size muffin pan (cups have ½-cup capacity) with baking-cup liners. Place chocolate and cocoa in medium bowl. Pour hot coffee over mixture and whisk until smooth. Set in refrigerator to cool completely, about 20 minutes. Whisk flour, sugar, salt, and baking soda together in medium bowl; set aside. Whisk oil, eggs, vinegar, and vanilla into cooled chocolate-cocoa mixture until smooth. Add flour mixture and whisk until smooth. Divide batter evenly among muffin pan cups. Place one slightly rounded teaspoon ganache filling on top of each cupcake. Bake until cupcakes are set and just firm to touch, 17 to 19 minutes. Cool cupcakes in muffin pan on wire rack until cool enough to handle, about 10 minutes. Carefully lift each cupcake from muffin pan and set on wire rack. Cool to room temperature before frosting, about 1 hour. FOR CREAMY CHOCOLATE FROSTING: Combine the sugar, egg whites, and salt in the bowl of a standing mixer, then place the bowl over a pan of simmering water. Heat the mixture, whisking gently but constantly, until slightly thickened and foamy and it registers 150 degrees on an instant-read thermometer, 2 to 3 minutes. Using the whisk attachment, beat the mixture on medium speed in a standing mixer until it reaches the consistency of shaving cream and is slightly cooled, 1 to 2 minutes. Add the butter, 1 piece at a time, until smooth and creamy. (The frosting may look curdled after half of the butter has been added; it will smooth with additional butter.) Once all the butter is added, add the cooled melted chocolate and the vanilla and mix until combined, about 30 seconds, scraping the beater and sides of the bowl with a rubber spatula as necessary. If, after you add the chocolate, the frosting seems too soft, chill it briefly and then re-whip until creamy. (The frosting can be made up to 24 hours in advance and refrigerated in an airtight container. When ready to frost, place the frosting in a microwave-safe container and microwave briefly until just softened, 5 to 10 seconds. Once warmed, stir until creamy.)

THE BEST CHOCOLATE CUPCAKES

Steps:

• For the cake: Preheat the oven to 350 degrees F. Line two 12-cup muffin tins with paper liners.
• Whisk together the cake flour, cocoa powder, granulated sugar, baking powder, baking soda and salt in the bowl of a stand mixer. Whisk together the buttermilk, coffee, oil, eggs and vanilla in a separate bowl.
• Pour half of the wet ingredients into the dry ingredients and beat on low speed just until combined. Scrape down the bowl then add the remaining wet ingredients and beat to combine. Scrape down the bowl and paddle. Increase the speed to medium and beat for a full minute.
• Fill the prepared cupcake tins 2/3 of the way full. Bake until a toothpick inserted in the center of each comes out clean and the top springs back when lightly pressed, 15 to 18 minutes.
• For the frosting: Melt the chocolate in a medium heatproof bowl set over simmering water in a medium saucepan. Remove from the simmering water and let it cool until room temperature, about 30 minutes.
• Beat the butter and salt in a large bowl with an electric mixer on high speed until light and fluffy, about 2 minutes. Reduce the speed to low, drizzle in the melted chocolate and beat until completely blended. Gradually beat in the confectioners' sugar, cocoa powder and vanilla. Increase the speed to high and beat until light and fluffy, about 2 minutes.
• Transfer the frosting to a pastry bag fitted with a large star tip. Decoratively pipe the frosting onto the cupcakes.
