Ingredients

Scale
  • 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
  • 3/4 teaspoon baking powder
  • 3/4 teaspoon salt
  • 2 large eggs
  • 1 cup buttermilk
  • 1/2 cup vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup hot brewed coffee
  • 1 cup heavy cream (for caramel)
  • 1 cup granulated sugar (for caramel)
  • 1/2 cup light corn syrup (for caramel)
  • 1/2 cup unsalted butter (for caramel)
  • 1 teaspoon sea salt (for caramel)
  • 1 cup prepared toffee bits (store-bought or homemade)
  • 1 cup powdered sugar (for frosting)
  • 1/2 cup unsalted butter, softened (for frosting)
  • 1/4 cup cocoa powder (for frosting)
  • 2 tablespoons milk (for frosting)

Instructions

  1. Prepare the Chocolate Cake Layers: Preheat your oven to 350 degrees F (175 degrees C). Grease and flour two 8-inch round cake pans. In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
  2. Add the eggs, buttermilk, oil, and vanilla extract to the dry ingredients. Beat with an electric mixer on medium speed for two minutes. Carefully stir in the hot coffee until the batter is smooth. The batter will be thin.
  3. Divide the batter evenly between the prepared pans. Bake for 30 to 35 minutes, or until a wooden pick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
  4. Make the Homemade Caramel Sauce: In a medium saucepan, combine the heavy cream, sugar, and corn syrup. Heat over medium heat, stirring until the sugar dissolves. Stop stirring once it boils. Cook without stirring until the mixture reaches 320 degrees F (160 degrees C) on a candy thermometer.
  5. Remove the pan from the heat. Carefully whisk in the butter until melted. Stir in the sea salt. Let the caramel cool slightly; it will thicken as it cools.
  6. Prepare the Chocolate Frosting: Beat the softened butter until creamy. Gradually add the powdered sugar and cocoa powder, alternating with the milk, until the frosting is smooth and spreadable.
  7. Assemble the Ultimate Chocolate Caramel Toffee Crunch Cake: Place one cooled cake layer on a serving plate. Spread about one-third of the chocolate frosting over the first layer. Drizzle generously with caramel sauce and sprinkle with half of the toffee bits.
  8. Place the second cake layer on top. Cover the top and sides of the entire cake with the remaining chocolate frosting. Drizzle the remaining caramel sauce over the top, allowing it to drip down the sides. Sprinkle the remaining toffee bits over the top for the crunch factor.
  9. Chill the cake for at least 30 minutes before slicing to allow the layers to set.

Notes

  • For the best texture, use room temperature buttermilk and eggs in your cake batter.
  • If you want a truly bakery-style cake, use high-quality Dutch-process cocoa powder for a deeper chocolate flavor.
  • You can make the caramel sauce up to one week ahead and store it covered in the refrigerator. Reheat gently before using to make it pourable.
  • Toffee bits can be made by crushing hard toffee candies or using pre-made English toffee pieces.
