Toffee Buttercream Cupcakes

Printer-Friendly Version

Yield: about 30 cupcakes
Ingredients:
For the cupcakes:
1 cup all-purpose flour
¾ cup unsweetened cocoa powder
1 tbsp. espresso powder
1 tsp. baking soda
½ tsp. salt
1 cup sugar
1 cup (2 sticks) unsalted butter, at room temperature
4 large eggs, at room temperature
2 tsp. vanilla extract
1 cup brewed coffee
1 cup toffee bits

For the ganache and toffee layer:
8 oz. bittersweet chocolate, finely chopped
1 cup heavy cream
3 tbsp. unsalted butter, at room temperature
1½-2 cups toffee bits

For the frosting:
5 large egg whites
1½ cups sugar
4 sticks unsalted butter, at room temperature
½ tsp. coarse salt
1 tbsp. vanilla extract
1/3 cup caramel sauce

Directions:
To make the cupcakes, preheat the oven to 350˚ F. Line cupcake pans with paper liners. In a medium bowl, combine the flour, cocoa powder, espresso powder, baking soda, and salt. In the bowl of an electric mixer, combine the sugar and butter and beat together on medium-high speed until light and fluffy, about 2-3 minutes. Beat in the eggs one at a time, mixing well after each addition. Blend in the vanilla. With the mixer on low speed, add in the dry ingredients in three additions, alternating with the coffee, beginning and ending with the dry ingredients. Mix each addition just until incorporated. Fold in the toffee bits with a spatula.

Divide the batter evenly between the prepared liners. Bake 18-20 minutes or until a toothpick inserted in the center comes out clean. Let cool in the pans 5-10 minutes before transferring to a wire rack to cool completely.

To make the ganache, place the chopped chocolate in a heatproof bowl. Add the cream to a saucepan and bring to a simmer. Remove from the heat and pour the hot cream over the chocolate; let stand 1-2 minutes. Whisk together until a smooth ganache forms. Whisk in the butter 1 tablespoon at a time until completely incorporated. Transfer the bowl to the fridge or freezer to chill the ganache to a pipeable consistency, whisking every 5-10 minutes to ensure even cooling. When slightly thickened, transfer to a pastry bag fitted with your tip of choice. Pipe a ring of ganache around the top of each cupcake, leaving a hole in the center. Add the toffee bits to a bowl and dip the ganache portion of each cupcake into the toffee bits, pressing very gently to adhere. Let the ganache set.

To make the frosting, combine the egg whites and the sugar in a heatproof bowl set over a pot of simmering water. Heat, whisking frequently, until the mixture reaches 160° F and the sugar has dissolved. Transfer the mixture to the bowl of a stand mixer fitted with the whisk attachment. Beat on medium-high speed until stiff peaks form and the mixture has cooled to room temperature, about 8 minutes. (The bowl should be cool to the touch.)

Reduce the speed to medium and add the butter, 2 tablespoons at a time, adding more once each addition has been incorporated. If the frosting looks soupy or curdled, continue to beat on medium-high speed until thick and smooth again, about 3-5 minutes more (or longer - don’t worry, it will come together!) Blend in the salt, vanilla, and caramel until smooth and completely incorporated, scraping down the sides of the bowl as needed.

Fill a pastry bag fitted with a decorative tip with the frosting and pipe a frilly pile of frosting on top of each cupcake, filling the hole in the center of the ganache. Top with additional toffee pieces, if desired.
