Ingredients

Scale

For the Rich Cocoa Layers

  • 1 3/4 cups all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 1 1/2 teaspoons baking soda
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon salt
  • 2 cups granulated sugar
  • 1 cup buttermilk (or milk mixed with 1 tablespoon white vinegar)
  • 1/2 cup vegetable oil
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup hot brewed coffee
  • 1 cup semi-sweet chocolate chips

For the Whipped Cream Frosting and Assembly

  • 1 cup salted caramel sauce (store-bought or homemade)
  • 1 cup heavy whipping cream
  • 1/4 cup powdered sugar
  • 1 teaspoon vanilla extract (for frosting)
  • 1 1/2 cups toffee bits (like crushed Heath or Skor bars)
  • 1/2 cup extra caramel sauce for drizzling

Instructions

  1. Prepare Baking Pans: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans and line the bottoms with parchment paper to prevent sticking.
  2. Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, baking powder, salt, and granulated sugar until evenly combined.
  3. Combine Wet Ingredients: In a separate bowl, mix the buttermilk, vegetable oil, eggs, and vanilla extract thoroughly.
  4. Make Cake Batter: Pour the wet ingredients into the dry ingredients and mix until just combined. Then carefully pour in the hot brewed coffee and blend on low speed until the batter is smooth. Stir in the semi-sweet chocolate chips gently. Expect the batter to be thin.
  5. Bake Cake Layers: Divide the batter evenly between the prepared cake pans. Bake for 30 to 35 minutes or until a wooden pick inserted into the center comes out clean or with a few moist crumbs. Let the cakes cool in the pans for 10 minutes, then invert onto wire racks to cool completely.
  6. Make Whipped Cream Frosting: While the cake cools, beat heavy whipping cream, powdered sugar, and vanilla extract together until stiff peaks form, creating a light and fluffy frosting.
  7. Assemble Cake: Place one cooled cake layer on a serving plate. Spread half of the salted caramel sauce evenly over the top, then sprinkle half of the toffee bits.
  8. Layer and Frost: Carefully place the second cake layer on top. Frost the entire cake, covering top and sides, with the whipped cream frosting.
  9. Finish Decoration: Drizzle the remaining caramel sauce over the cake, allowing it to drip down the sides, and sprinkle the rest of the toffee bits on top for crunchy texture.
  10. Chill Before Serving: Refrigerate the assembled cake for at least 30 minutes to let the layers set before slicing and serving.

Notes

  • For a richer chocolate flavor, substitute standard cocoa powder with dark Dutch-processed cocoa powder.
  • If you want a more stable frosting suitable for warm conditions or transport, replace the whipped cream with a chocolate buttercream frosting.
  • Add the final toffee bit topping just before serving to maintain maximum crunchiness; toffee softens when exposed to moisture over time.
