Death by Chocolate Cupcakes

Heat oven to 350°F. Place paper baking cup in each of 24 regular-size muffin cups.

Make and bake cake mix as directed on box for cupcakes, using water, oil and eggs and adding vanilla. Cool 10 minutes; remove from pans to cooling racks. Cool completely.

Meanwhile, place bittersweet chocolate in heatproof bowl. In 1-quart saucepan, heat whipping cream until almost boiling. Pour over chocolate; let stand 5 minutes. Stir until chocolate is melted and ganache is smooth. Cool 30 minutes.

Cut out small section from top center of each cupcake; reserve cutout pieces. Spoon 1 1/2 teaspoons ganache into each hole; replace removed cake pieces. Cool remaining ganache 1 hour. Beat with electric mixer on medium speed until spreadable. Spread or pipe onto cupcakes. Drizzle with chocolate topping.
