Ingredients

Scale

Rich Cocoa Cake 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 1 cup milk + 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

Whipped Cream Frosting & 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 (crushed Heath or Skor bars)
  • 1/2 cup extra caramel sauce for drizzling

Instructions

  1. Prepare Cake Pans: Preheat 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 flour, cocoa powder, baking soda, baking powder, salt, and sugar until well combined.
  3. Combine Wet Ingredients: In another bowl, mix buttermilk, vegetable oil, eggs, and vanilla extract until smooth.
  4. Combine Mixtures: Pour wet ingredients into dry ingredients and mix until just combined. Then carefully add hot brewed coffee and stir gently until the batter is smooth and thin. Fold in chocolate chips evenly.
  5. Bake Cake Layers: Divide batter evenly between prepared pans. Bake 30 to 35 minutes, or until a wooden pick inserted into the center comes out clean or with a few moist crumbs. Remove from oven and let cakes cool in pans for 10 minutes.
  6. Cool Cakes Completely: Invert cakes onto wire racks to cool completely before frosting to prevent melting.
  7. Prepare Whipped Cream Frosting: Beat heavy whipping cream, powdered sugar, and vanilla extract using a mixer until stiff peaks form, creating a light, airy frosting.
  8. Assemble Cake: Place one cooled cake layer on serving plate. Spread half of the salted caramel sauce evenly over top, then sprinkle half of the toffee bits over the caramel layer.
  9. Add Second Layer and Frost: Carefully place the second cake layer on top. Frost the entire cake, including top and sides, with whipped cream frosting.
  10. Decorate and Chill: Drizzle remaining caramel sauce over the top to let it cascade down the sides. Sprinkle remaining toffee bits for a crunchy finish. Refrigerate the assembled cake for at least 30 minutes to set before slicing and serving.

Notes

  • Use dark Dutch-processed cocoa powder for a deeper, richer chocolate flavor.
  • For a more stable frosting that holds up in warm environments or transport, substitute whipped cream with chocolate buttercream.
  • Add the final toffee bit topping just before serving to maintain maximum crunch, as moisture from frosting and caramel can soften toffee over time.
  • You can prepare the cake layers up to two days in advance; wrap tightly and store at room temperature or freeze for up to one month. Thaw overnight before assembling.
  • Whipped cream frosting is best made the day you assemble the cake as it doesn’t keep well in the fridge beyond 24 hours.
  • If caramel filling is too stiff, gently warm it for 10-15 seconds to achieve spreadability.
