Adapted from Cook’s Illustrated: Ultimate Chocolate Cupcakes with Ganache Filling
Ingredients
Ganache Filling:
- 2 ounces bittersweet chocolate, chopped fine (see note)
- ¼ cup heavy cream
- 1 tablespoon confectioners’ sugar
Chocolate Cupcakes: Makes about 16 cupcakes
- 3 ounces bittersweet chocolate, chopped fine
- 1/3 cup (1 ounce) Dutch-processed cocoa
- 1/2 cup hot water
- ¾ cup AP flour
- ¾ cup (5¼ ounces) granulated sugar
- ½ teaspoon table salt
- 6 tablespoons vegetable oil
- 2 large eggs, room temperature
- 1/4 c buttermilk
- 1 teaspoon vanilla extract
- 2 teaspoons white vinegar
- ½ teaspoon baking soda
Frosting:
- ¼ cups unsalted butter, at room temperature
- 1 cup powdered sugar
- ¾ cup Dutch-processed cocoa powder
- Pinch of salt
- ¾ cup light corn syrup
- 1 teaspoon vanilla extract
- 8 ounces chocolate (milk, semisweet or dark), melted and cooled
Preparation
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.
Chocolate Cupcakes:
Adjust oven rack to middle position and heat oven to 350 degrees. Line standard-sized muffin pan (cups have ½-cup capacity) with baking-cup liners. Place chocolate and cocoa in medium bowl. Pour water over mixture and whisk until smooth. Set in refrigerator to cool completely, about 20 minutes. Whisk flour, sugar and salt together in medium bowl; set aside.
Whisk oil, eggs, buttermilk and vanilla into cooled chocolate-cocoa mixture until smooth. Add flour mixture and whisk until smooth.
In a small bowl, combine the baking soda and vinegar, then stir into the batter.
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.
Frosting: In a food processor, process the butter, sugar, cocoa powder and salt until smooth, about 30 seconds, scraping the sides of the bowl as needed. Add the corn syrup and vanilla extract and process until just combined, 5 to 10 seconds. Scrape the sides of the bowl, then add the chocolate and pulse until smooth and creamy, 10 to 15 one-second pulses. Frost the cupcakes as desired. The frosted cupcakes can be kept in an airtight container at room temperature for up to 3 days.
