I could hardly contain my excitement when a coworker recently chose these toffee crunch cupcakes as her birthday selection.  This is one intense cupcake.  It starts with a chocolate cupcake base with toffee bits mixed in, topped with a ring of ganache coated in toffee bits, and finished off with a pretty little cloud of caramel Swiss meringue buttercream frosting.  Toffee has long been a favorite treat of Ben’s so he was pretty psyched about the idea of these and even more excited when there were extras left over for him to sample.

I did wonder if the toffee flavor might be masked by the intense chocolate cake or the rich caramel frosting, but the flavors were nicely balanced.  You can definitely taste all the components but the toffee still plays a starring role.  My only criticism is that if made in advance, the toffee bits soften slightly and lose the “crunch”, making the name a bit less apt.  Nevertheless they still tasted great and if I were really going for that crunch component, an extra sprinkle of toffee on top of the frosting just before serving would surely do the trick.  If you have a toffee lover in your life, you might just make their day with these cupcakes.

  • Yield about 30 cupcakes

Ingredients

For the cupcakes:
2 cups all-purpose flour
¾ cup unsweetened cocoa powder
1 tbsp. espresso powder
1 tsp. baking soda
½ tsp. salt
2 cups 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

  • 01

    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.

  • 02

    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.

  • 03

    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.)

  • 05

    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.

  • 06

    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.
