Ingredients

Scale
  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 1 cup buttermilk
  • 1/2 cup vegetable oil
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup hot strong brewed coffee
  • 1 (14 ounce) can sweetened condensed milk
  • 1/2 cup heavy cream
  • 1/4 cup unsalted butter
  • 1 teaspoon sea salt
  • 1 cup toffee bits (crushed candy bars or homemade brittle)
  • 1 cup chocolate frosting (your favorite recipe or store-bought)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  2. In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt for the cake.
  3. Add the buttermilk, oil, eggs, and vanilla extract to the dry ingredients. Beat with an electric mixer on medium speed for two minutes.
  4. Carefully stir in the hot coffee until the batter is smooth. The batter will be thin.
  5. 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.
  6. Prepare the caramel: In a medium saucepan over medium heat, combine the sweetened condensed milk, heavy cream, butter, and sea salt. Stir constantly until the butter melts and the mixture comes to a gentle boil. Reduce heat to low and simmer for 5 to 7 minutes, stirring often, until the mixture thickens slightly. Remove from heat and let it cool slightly.
  7. Once the cakes are cool, place one layer on a serving plate. Spread half of the chocolate frosting over the top. Drizzle half of the slightly cooled caramel over the frosting. Sprinkle with half of the toffee bits.
  8. Place the second cake layer on top. Frost the top and sides of the entire cake with the remaining chocolate frosting.
  9. Drizzle the remaining caramel over the top of the cake, allowing some to drip down the sides. Sprinkle the remaining toffee bits over the top for the final crunch layer.

Notes

  • For the moistest cake, do not overbake. Check for doneness early.
  • You can make the caramel sauce a day ahead and store it in the refrigerator; warm it gently before using.
  • If you prefer a thicker filling, simmer the caramel mixture for a few extra minutes until it reaches a thicker consistency.
