  • Cocoa powder (unsweetened) – ¾ cup (75g)
  • Baking powder – 1 ½ tsp
  • Baking soda – 1 ½ tsp
  • Salt – 1 tsp
  • Large eggs – 2, room temperature
  • Buttermilk – 1 cup (240ml) or milk with 1 tbsp lemon juice
  • Vegetable oil – ½ cup (120ml)
  • Boiling water – 1 cup (240ml)
  • Vanilla extract – 2 tsp
  • Heavy cream – 1 cup (240ml) for ganache
  • Bittersweet or semi-sweet chocolate chips – 8 oz (225g)
  • Unsalted butter – 2 tbsp, softened
  • White chocolate chips – ½ cup (90g) for gold drip
  • Heavy cream – ¼ cup (60ml) for gold drip
  • Edible gold luster dust – 1 tsp mixed with 1 tbsp clear vanilla extract or vodka
  • Black edible food coloring gel for zodiac design

Instructions

  1. Preheat oven to 350°F (175°C). Grease two 8-inch cake pans and line bottoms with parchment paper.
  2. In a large bowl, sift together flour, sugar, cocoa powder, baking powder, baking soda, and salt. Whisk to combine.
  3. In a separate bowl, beat eggs, buttermilk, vegetable oil, and vanilla extract until smooth. Pour into dry ingredients and stir gently.
  4. Slowly add boiling water to the batter, stirring carefully. Batter will be thin.
  5. Divide batter evenly between prepared pans. Bake 30-35 minutes or until toothpick inserted comes out clean.
  6. Cool cakes in pans for 10 minutes, then transfer to wire racks to cool completely (about 1 hour).
  7. For ganache, heat 1 cup heavy cream until simmering. Pour over chocolate chips in a bowl. Let sit 5 minutes, then stir until smooth. Add softened butter and mix until glossy. Chill until spreadable.
  8. Assemble cake by placing one layer on serving plate. Spread ganache evenly. Top with second layer and cover entire cake with thin crumb coat of ganache. Chill 20 minutes.
  9. For gold drip, heat ¼ cup heavy cream and pour over white chocolate chips. Stir until smooth. Mix edible gold dust with vanilla extract or vodka and brush onto white chocolate ganache to create gold drip effect.
  10. Using spoon or piping bag, drip gold ganache over edges of chilled cake. Chill briefly to set.
  11. Paint zodiac constellation and symbols on cake with black edible gel using fine food-safe brush. Add silver edible dust dots for stars. Take time for precision.

Notes

The batter will be thin due to boiling water—do not add extra flour. Chill ganache until spreadable but not firm. Control gold drip with spoon or piping bag and chill crumb coat well before applying drip. Practice zodiac painting on parchment paper first. Use a turntable if available for easier decorating.
