Equipment

  • Mixing bowls
  • Electric mixer
  • Saucepan
  • Whisk
  • Cake pans (two or three 8-inch)
  • Cooling rack
  • Offset spatula
  • Cake stand

Ingredients
  

For Cake:

  • 2 cups all-purpose flour
  • 1 cup cocoa powder
  • 1 ½ tsp baking powder
  • 1 tsp baking soda
  • 1 cup butter, melted
  • 1 ½ cups sugar
  • 4 eggs
  • 1 cup buttermilk
  • 1 tsp vanilla extract

For Salted Caramel Buttercream:

  • 1 cup butter, softened
  • 3 cups powdered sugar
  • ½ cup salted caramel sauce (homemade or store-bought)

For Caramel Sauce:

  • 1 cup sugar
  • 6 tbsp butter
  • ½ cup heavy cream
  • 1 tsp sea salt

For Ganache:

  • 8 oz dark chocolate (60–70% cocoa), chopped
  • 1 cup heavy cream

Instructions
 

  • Bake Cake Layers: Mix dry ingredients. Beat butter, sugar, and eggs until fluffy. Add buttermilk and vanilla, then fold in dry mix. Divide into pans and bake at 350°F (175°C) for 30–35 minutes. Cool completely.
  • Make Caramel Sauce: Melt sugar until golden. Add butter, then cream. Stir in sea salt. Cool.
  • Prepare Buttercream: Beat butter until fluffy. Add powdered sugar gradually, then mix in cooled caramel sauce until smooth.
  • Create Ganache: Heat cream until simmering. Pour over chocolate. Stir until glossy. Cool slightly.
  • Assemble Cake: Layer cake with buttercream between tiers. Frost outside with buttercream. Drizzle caramel over top.
  • Finish with Ganache: Pour ganache over cake, letting it drip down sides. Garnish with chocolate shavings or caramel swirls.

Notes

  • Use high-quality chocolate for both cake and ganache—it makes a big difference.
  • Cool caramel completely before adding to buttercream to prevent splitting.
  • Chill cake layers before assembly for neat, professional results.
  • Store in fridge for up to 4 days; freeze slices for up to 2 months.
  • Garnish with sea salt flakes for a striking finish.
