  • 1 teaspoon vanilla extract
  • 1/2 cup (115g) unsalted butter, softened (for frosting)
  • 2 cups (240g) powdered sugar, sifted (for frosting)
  • 1/4 cup (25g) unsweetened cocoa powder (for frosting)
  • 1 1/2 tablespoons (15g) black sesame powder (for frosting)
  • 1/4 cup (60ml) heavy cream (for frosting)
  • 1/2 teaspoon vanilla extract (for frosting)
  • White chocolate or white icing (for spider web decoration)
  • Black food coloring gel (optional)

Instructions

  1. Preheat oven to 350°F (175°C) and grease two 8-inch cake pans. Line bottoms with parchment paper.
  2. Sift together flour, cocoa powder, black sesame powder, baking powder, baking soda, and salt in a medium bowl.
  3. In a large bowl, whisk sugar and vegetable oil until blended. Add eggs one at a time, mixing well after each.
  4. Stir in buttermilk and vanilla extract.
  5. Gradually fold dry ingredients into wet mixture using a rubber spatula until just combined.
  6. Divide batter evenly between pans and tap to release air bubbles.
  7. Bake 30-35 minutes or until toothpick comes out mostly clean with a few moist crumbs.
  8. Cool in pans 10 minutes, then transfer to racks to cool completely.
  9. For frosting, beat softened butter until creamy. Gradually add powdered sugar and cocoa powder on low speed.
  10. Add black sesame powder and vanilla extract, then heavy cream bit by bit until spreadable.
  11. Place one cake layer on plate, spread thick frosting layer. Top with second layer and crumb coat. Chill 15 minutes.
  12. Apply final smooth frosting layer.
  13. Melt white chocolate gently. Pipe concentric circles from center outward. Drag toothpick from center to edges to create spider web.
  14. Work quickly before white chocolate sets.

Notes

Toast and grind black sesame seeds fresh for best flavor. Sift dry ingredients to aerate and avoid lumps. Fold batter gently to prevent toughness. Use room temperature eggs and buttermilk for smooth batter. Chill cake between frosting layers for smooth finish. Pipe spider web quickly before white chocolate sets.
