Instructions
Make the Chocolate Sponge:
- Preheat oven to 170°C (340°F). Line two 8-inch round pans with parchment paper.
- Sift together cake flour, cocoa powder, and salt. Set aside.
- In a large bowl, whisk egg yolks with 1/3 of the sugar until pale and thick.
- Add milk, oil, and vanilla to the yolk mixture. Mix well.
- Fold the flour mixture into the yolk mixture until just combined.
- In a clean bowl, whip egg whites until foamy. Gradually add remaining sugar and whip to stiff peaks.
- Gently fold meringue into chocolate batter in three additions.
- Divide between pans and bake for 25-30 minutes until a toothpick comes out clean.
- Cool completely on wire racks.
Prepare the Ganache:
- Place chopped chocolate in a large bowl.
- Heat cream and honey in a saucepan until just simmering.
- Pour hot cream over chocolate and let sit for 2 minutes.
- Stir from center outward until smooth and glossy.
- Add butter and vanilla, stir until incorporated.
- Let cool to room temperature, stirring occasionally.
Assemble the Cake:
- Cut each cake layer in half horizontally.
- Place first layer on serving plate and spread with ganache.
- Repeat layering with remaining cake and ganache.
- Cover entire cake with remaining ganache.
- Decorate with gold leaf, chocolate shavings, and berries.
- Refrigerate for 1 hour before serving.
Korean Chocolate Secrets
Perfect Ganache
Korean chocolate ganache is silkier than Western versions. The addition of honey creates a unique glossy finish and subtle sweetness.
Cocoa Quality
Use high-quality Dutch-processed cocoa powder for the deepest chocolate flavor. Korean bakeries often use premium Japanese or European cocoa.
Temperature Control
Let the ganache cool to the right consistency - it should coat the back of a spoon but still be pourable for the smoothest finish.
