Ingredients

Scale
  • For the Chocolate Cake:
  • 1 3/4 cups all-purpose flour
  • 1 3/4 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 1 1/2 teaspoons baking soda
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon salt
  • 2 large eggs
  • 1 cup buttermilk
  • 1/2 cup vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup hot strong brewed coffee
  • For the Salted Caramel Filling:
  • 1 cup granulated sugar
  • 1/2 cup water
  • 1/2 cup heavy cream, warmed
  • 6 tablespoons unsalted butter, cut into pieces
  • 1 teaspoon vanilla extract
  • 1 teaspoon coarse sea salt
  • For the Toffee Crunch:
  • 1 cup granulated sugar
  • 1/2 cup unsalted butter
  • 1/4 cup water
  • 1/2 cup heavy cream
  • 1 teaspoon baking soda
  • 1 cup toffee bits (store-bought or homemade)
  • For the Chocolate Frosting:
  • 1 cup (2 sticks) unsalted butter, softened
  • 3 1/2 cups powdered sugar
  • 1/2 cup unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract
  • 4 tablespoons milk or heavy cream

Instructions

  1. Prepare the Chocolate Cake: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans. Whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt in a large bowl. Add the eggs, buttermilk, oil, and vanilla; beat on medium speed for two minutes. Carefully stir in the hot coffee. Divide batter evenly between the prepared pans. Bake for 30 to 35 minutes, or until a wooden pick inserted into the center comes out clean. Cool in pans for 10 minutes, then invert onto a wire rack to cool completely.
  2. Make the Toffee Crunch: Line a baking sheet with parchment paper. In a medium saucepan, combine the 1 cup sugar, 1/2 cup butter, and 1/4 cup water. Cook over medium heat, stirring until the sugar dissolves. Stop stirring and boil until the mixture reaches a deep amber color (about 300°F). Remove from heat. Carefully whisk in the heavy cream (mixture will bubble vigorously). Stir in the remaining 1 cup sugar, butter, and water. Cook until it reaches a deep amber color. Remove from heat. Quickly whisk in the baking soda; the mixture will foam up. Pour onto the prepared baking sheet and spread thinly. Let cool completely, then break into small, crunchy pieces. Stir these pieces into the toffee bits. Set aside.
  3. Prepare the Salted Caramel Filling: Combine 1 cup sugar and 1/2 cup water in a saucepan. Cook over medium heat without stirring until the sugar dissolves and turns a deep amber color. Remove from heat. Carefully pour in the warmed heavy cream (it will bubble). Stir until smooth. Add the butter pieces, vanilla, and salt. Stir until the butter melts. Let the caramel cool until it thickens to a spreadable consistency.
  4. Make the Chocolate Frosting: Beat the softened butter in a large bowl until creamy. Gradually add the powdered sugar and cocoa powder, alternating with the milk, beating until smooth. Mix in the salt and vanilla. If the frosting is too thick, add a little more milk.
  5. Assemble the Cake: Level the cake layers if necessary. Place one cake layer on your serving plate. Spread half of the salted caramel filling over the first layer. Sprinkle generously with half of the toffee crunch mixture. Top with the second cake layer. Frost the entire cake with the chocolate frosting. Press the remaining toffee crunch mixture onto the top and sides of the cake for a bakery look.

Notes

  • For a richer caramel flavor, use a high-quality sea salt.
  • If you are planning your weekly meals, this cake is a great centerpiece for your weekend menu, though it is not a substitute for structured meal planning or best meal delivery services.
  • You can prepare the toffee crunch up to three days ahead and store it in an airtight container at room temperature.
