Ingredients
  

Main Ingredients
  • 1 ½ cups (120g) Dutch-processed black cocoa powder Essential for charcoal color
  • 3 cups (375g) All-purpose flour
  • 3 cups (600g) Granulated sugar
  • 3 large Eggs Room temperature
  • 1 ½ cups (360ml) Buttermilk Full-fat
  • ¾ cup (180ml) Vegetable oil
  • 1 ½ cups (360ml) Boiling water or hot coffee To bloom the cocoa
  • 1 tbsp (15g) Baking powder
  • 1 tbsp (15g) Baking soda
  • 2 cups (480ml) Heavy whipping cream
  • 2 cups (340g) 60% dark chocolate chips High quality for shine

Equipment

  • 3 8-inch round cake pans Deep pans recommended
  • 1 Revolving cake turntable For even ganache application
  • 1 Matte black ceramic plate For serving

Method
 

Baking the Layers
  1. Sift together flour, black cocoa, sugar, baking powder, baking soda, and salt in a large bowl.
  2. Whisk eggs, buttermilk, and oil until smooth. Gradually add to dry ingredients. Stir in boiling water last.
  3. Divide into three 8-inch pans and bake at 350°F (175°C) for 30-35 minutes until a skewer comes out clean.
Assembly
  1. Trim the cooled cake tops and crumble them into irregular pieces to create 'volcanic rock'.
  2. Pour hot cream over chocolate chips. Let sit for 5 minutes, then whisk until glossy.
  3. Layer cakes with ganache. Pour remaining ganache over the top, allowing it to drip like lava. Press crumbs into the sides while wet.

Notes

Use black cocoa specifically for the deep charcoal color; regular cocoa will result in a brown cake.
Ensure the ganache is lukewarm when pouring for the perfect controlled drip.
