Equipment

  • Stand mixer or hand mixer
  • Whisk
  • Spatula
  • 3 Springform pans (Ø 20 cm)
  • Sifter
  • Cooling rack
  • 1 Sharp knife

Ingredients

  • 330 g dark chocolate couverture
  • 270 g butter
  • 6 size M eggs
  • 375 g sugar
  • 3 tsp vanilla extract
  • 280 g wheat flour Type 405
  • 120 g starch
  • 135 g baking cocoa
  • 3 tsp baking powder (leveled)
  • 1 tsp baking soda (leveled)
  • 3 tsp apple cider vinegar
  • 300 ml buttermilk

Instructions

  • Preheat the oven to 180°C (160°C for a fan oven). Grease three springform pans (Ø 20 cm) with butter and dust with flour.
  • Chop dark chocolate and melt with butter over a water bath until smooth.
  • In a separate bowl, beat eggs with sugar and vanilla until light and airy.
  • Pour in the melted chocolate mixture and blend well.
  • Sift together flour, starch, cocoa, and baking powder, and fold into the wet ingredients.
  • Mix baking soda with apple cider vinegar and add it to the batter along with buttermilk, stirring until combined.
  • Divide the batter evenly among the prepared pans and bake for about 35 minutes.
  • Allow cakes to cool completely before assembling.
  • For the Buttercream: Combine sugar and water in a pot over medium heat, stir until sugar dissolves.
  • In a mixing bowl, beat egg whites until stiff peaks form. Slowly pour in hot sugar syrup while continuing to mix until glossy and cool.
  • Incorporate the soft butter gradually, mixing until you achieve a smooth, creamy buttercream.
  • For decoration, melt dark chocolate with cream and butter until smooth.
  • Decorate the cake with chocolate, various cookies, sweets, and a cake figure '18'.

Notes

Don’t rush the cooling process; warm layers can cause the frosting to melt. Keep the eggs and butter at room temperature for easier mixing. Make ahead by baking the layers a day in advance and store wrapped in plastic until ready to assemble. Experiment with decorations to match the occasion; you can use edible glitter, fresh berries, or colorful candies.
