Ingredients

Scale
  • For the Chocolate Cake Layers: 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 water or hot brewed coffee
  • For the Salted Caramel: 1 cup granulated sugar
  • 1/4 cup water
  • 1/2 cup heavy cream, warmed
  • 4 tablespoons unsalted butter, cut into pieces
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon sea salt
  • For the Toffee Crunch: 1 cup granulated sugar
  • 1/2 cup unsalted butter
  • 1/4 cup light corn syrup
  • 1 teaspoon baking soda
  • 1 cup toffee bits (for topping)
  • For Assembly/Frosting: 1 cup (2 sticks) unsalted butter, softened
  • 3 cups powdered sugar
  • 1/2 cup cocoa powder
  • 1/2 cup heavy cream
  • 1 teaspoon vanilla extract

Instructions

  1. Prepare the Toffee Crunch: Line a baking sheet with parchment paper. Combine sugar, butter, and corn syrup in a saucepan over medium heat. Stir until the sugar dissolves, then stop stirring. Boil until the mixture reaches 300°F (hard crack stage). Remove from heat, quickly stir in baking soda, then pour onto the prepared sheet. Let cool completely, then break into small, crunchy pieces. Set aside 1 cup of the broken toffee for the topping.
  2. Bake the Chocolate Layers: Preheat your oven to 350°F. Grease and flour three 8-inch round cake pans. Whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt in a large bowl. Add eggs, buttermilk, oil, and vanilla. Beat on medium speed for two minutes. Carefully stir in the hot water or coffee. Divide batter evenly among the pans. Bake for 30 to 35 minutes, or until a toothpick comes out clean. Cool in pans for 10 minutes, then invert onto a wire rack to cool completely.
  3. Make the Salted Caramel: Combine sugar and water in a saucepan over medium heat. Stir until sugar dissolves, then stop stirring. Cook until the mixture turns a deep amber color. Remove from heat. Carefully whisk in the warm heavy cream (it will bubble vigorously). Whisk in the butter, vanilla, and sea salt until smooth. Let the caramel cool until it thickens slightly but is still pourable.
  4. Prepare the Chocolate Frosting: Beat the softened butter until creamy. Gradually add powdered sugar and cocoa powder, alternating with the heavy cream and vanilla. Beat until light and fluffy.
  5. Assemble the Cake: Place the first cake layer on a serving plate. Spread a layer of frosting, then drizzle generously with salted caramel. Sprinkle with some of the crushed toffee (not the topping bits). Repeat with the second layer. Top with the final cake layer. Frost the entire cake with the remaining chocolate frosting.
  6. Finish the Cake: Drizzle the top of the cake with remaining salted caramel. Press the reserved 1 cup of toffee bits around the sides and sprinkle over the top for the final crunch.

Notes

  • For the moistest chocolate layers, use hot brewed coffee instead of hot water; the coffee deepens the cocoa flavor without making the cake taste like coffee.
  • If your caramel is too thin after cooling, you can gently reheat it for a minute or two to adjust consistency before drizzling.
  • You can make the toffee bits up to three days ahead of time and store them in an airtight container at room temperature.
