Description

A showstopping vanilla sponge layered and cloaked in silky Korean-style Swiss meringue buttercream, finished with hand-piped buttercream flowers that look like a bouquet and taste like a dream.


Ingredients

  • Cake Flour: 2 1/2 cups, for a tender, fine crumb
  • Baking Powder: 2 teaspoons, to lift the sponge
  • Salt: 1/2 teaspoon, to balance sweetness
  • Unsalted Butter: 1 cup softened, for richness and moisture
  • Granulated Sugar: 1 3/4 cups, for sweetness and structure
  • Eggs: 4 large, for binding and stability
  • Milk: 1 cup, for moisture and tenderness
  • Vanilla Extract: 2 teaspoons, for warm aroma
  • Unsalted Butter (Buttercream): 1 cup, for a smooth, stable base
  • Egg Whites (Buttercream): 5 large, to create a silky meringue
  • Granulated Sugar (Buttercream): 1 1/2 cups, to sweeten and stabilize
  • Gel Food Coloring: as needed, to tint flowers without thinning

Instructions

  1. Preheat Your Equipment: Heat oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment.
  2. Combine Ingredients: Whisk cake flour, baking powder, and salt. In a separate bowl, cream softened butter and sugar until pale and fluffy, 3 to 4 minutes. Beat in eggs one at a time, then mix in vanilla. Add dry ingredients alternately with milk, starting and ending with dry, mixing just until combined.
  3. Prepare Your Cooking Vessel: Divide batter evenly between prepared pans and smooth the tops.
  4. Assemble the Dish: Bake 25 to 30 minutes until a toothpick comes out clean. Cool in pans 10 minutes, then turn out to cool completely.
  5. Cook to Perfection: For buttercream, whisk egg whites and sugar over a simmering water bath, stirring, until sugar dissolves and mixture is warm to the touch. Transfer to mixer and whip to glossy stiff peaks. With mixer running on medium, add butter a tablespoon at a time until silky and smooth. Tint portions with gel colors.
  6. Finishing Touches: Level cooled cakes if needed. Apply a thin crumb coat of buttercream, chill until set, then add a smooth final coat. Pipe flowers on parchment squares, chill to firm, then transfer to cake and add leaves.
  7. Serve and Enjoy: Let the cake sit 15 to 20 minutes at room temperature for the buttercream to soften slightly, then slice and savor.

Notes

  • Chill Tools: Keep piping tips and small buttercream portions cool to help flowers hold shape.
  • Use Gel Colors: Gel coloring preserves consistency while yielding soft pastel tones.
  • Crumb Coat: A quick set in the fridge prevents stray crumbs in the final finish.
  • Test Tints: Color a teaspoon of buttercream first to preview intensity before tinting the whole batch.
