Ingredients
  

For the Chocolate Sponge
  • 4 pieces eggs separated
  • 150 g sugar
  • 2 tbsp hot water to fluff egg mixture
  • 120 g flour
  • 1 tsp baking powder
  • 2 tbsp cocoa powder
  • a pinch salt
For the Buttercream Filling
  • 500 ml milk
  • 3 tbsp flour for thickening
  • 200 g unsalted butter softened
  • 150 g powdered sugar
  • 1 tbsp rum
For Coating and Decoration
  • 100 g desiccated coconut
  • 100 g dark chocolate
  • 1 tsp vegetable oil to glaze chocolate

Equipment

  • Oven
  • Mixing Bowls
  • Electric Mixer
  • Sieve
  • Baking Sheets
  • Parchment Paper
  • Saucepan
  • Round Cookie Cutter
  • Double Boiler or Heatproof Bowl

Method
 

  1. Step 1: Preheat oven to 180°C and line two baking sheets with parchment paper.
  2. Step 2: Separate eggs. Beat egg yolks with sugar and hot water until pale and fluffy.
  3. Step 3: Sift together flour, baking powder, and cocoa powder. Gently fold into egg yolk mixture.
  4. Step 4: In a clean bowl, whisk egg whites with a pinch of salt until stiff peaks form. Carefully fold into the batter to keep it airy.
  5. Step 5: Spread batter evenly on the two baking sheets. Bake for about 20 minutes. Test with a skewer; if it comes out clean, remove and cool completely.
  6. Step 6: For the cream filling, whisk milk and flour until smooth. Heat gently while stirring until thickened. Cover with cling film directly on surface and cool completely.
  7. Step 7: Beat butter with powdered sugar and rum until creamy. Gradually mix in the cold milk-flour mixture to form a smooth buttercream.
  8. Step 8: Spread about two-thirds of the buttercream on one sponge layer. Place the second layer on top.
  9. Step 9: Use a round cutter to cut small cake rounds from the layered sponge.
  10. Step 10: Spread remaining buttercream around the sides of each cake round. Roll them in desiccated coconut until fully coated.
  11. Step 11: Melt dark chocolate with vegetable oil over a double boiler until shiny and smooth. Drizzle or spoon chocolate over tops of cake rounds.
  12. Step 12: Let chocolate set before serving or packaging the cakes.

Notes

For a vegan version, substitute eggs with applesauce or flaxseed gel and butter with plant-based margarine. Try vanilla extract or orange liqueur instead of rum for different flavors. Add chopped nuts to the coconut coating for extra texture. White chocolate glaze also works beautifully. Store in an airtight container in the fridge up to 3 days; freeze without chocolate glaze for longer storage.
