Equipment Needed

  • Two 9-inch round cake pans

  • Mixing bowls

  • Electric mixer

  • Saucepan

  • Rubber spatula

  • Cooling racks

  • Offset spatula

Instructions

Step 1: Prepare the Cake Pans and Oven

Preheat oven to 350°F (175°C).
Grease and line two 9-inch round cake pans with parchment paper.

Step 2: Make the Chocolate Cake Batter

In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt.

Add eggs, buttermilk, oil, and vanilla extract. Mix until smooth.

Slowly pour in hot coffee or water and mix until fully combined. The batter will be thin.

Divide batter evenly between prepared pans.

Step 3: Bake the Cakes

Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.

Allow cakes to cool in pans for 10 minutes, then transfer to wire racks to cool completely.

Step 4: Make the Caramel Sauce

In a saucepan over medium heat, melt sugar, stirring constantly, until it turns amber.

Add butter and stir until melted.

Slowly pour in heavy cream while stirring. Be careful, as the mixture will bubble.

Stir in salt. Remove from heat and allow caramel to cool slightly.

Step 5: Prepare the Chocolate Frosting

Beat softened butter until creamy.

Add powdered sugar and cocoa powder gradually, mixing on low speed.

Add heavy cream and vanilla extract. Beat until smooth and fluffy. Adjust consistency as needed.

Step 6: Assemble the Cake

Place one cake layer on a serving plate.

Spread a layer of chocolate frosting over the top.

Drizzle caramel sauce generously and sprinkle with toffee bits.

Place the second cake layer on top.

Frost the top and sides of the cake evenly.

Step 7: Decorate

Drizzle additional caramel sauce over the top.

Sprinkle generously with toffee bits.

Add chocolate shavings or drizzle if desired.

Tips for Success
