Ingredients

Scale
  • 1 cup (227g) unsalted butter, browned and cooled slightly
  • 1 ¾ cups (350g) granulated sugar
  • 4 large eggs, room temperature
  • 2 ½ cups (312g) all-purpose flour, sifted
  • 2 ½ tsp baking powder
  • ½ tsp salt
  • 1 cup (240ml) whole milk, room temperature
  • 2 tsp pure vanilla extract
  • 6 tbsp (85g) unsalted butter (for caramel)
  • ½ cup (100g) light brown sugar
  • ½ cup (120ml) heavy cream, warmed
  • 1 tsp pure vanilla extract (for caramel)
  • Pinch of sea salt
  • 1 cup (227g) unsalted butter, softened (for frosting)
  • 3 ½ cups (420g) powdered sugar, sifted
  • 1 tsp vanilla extract (for frosting)
  • 23 tbsp heavy cream (for frosting consistency)
  • Edible gold leaf sheets

Instructions

  1. Brown the Butter: In a medium saucepan over medium heat, melt 1 cup (227g) unsalted butter. Swirl often as it melts and watch carefully until it foams and turns deep golden brown with a nutty aroma (about 5-7 minutes). Remove from heat and cool slightly.
  2. Prepare Cake Batter: Preheat oven to 350°F (175°C). Grease and flour two 8-inch round cake pans. In a large bowl, whisk together sifted flour, baking powder, and salt. In a stand mixer, beat browned butter and granulated sugar on medium speed until smooth and creamy (2-3 minutes).
  3. Add eggs one at a time, beating well after each. Mix in vanilla extract. Alternate adding dry ingredients and milk in three additions, starting and ending with dry. Fold gently to combine without overmixing.
  4. Bake the Cake: Divide batter evenly between pans and smooth tops. Bake 30-35 minutes or until toothpick inserted in center comes out clean. Cool in pans 15 minutes, then transfer to wire racks to cool completely.
  5. Make Brown Butter Caramel: In the same saucepan, melt 6 tbsp butter over medium heat until browned. Stir in light brown sugar and warm heavy cream. Simmer gently, stirring constantly, until caramel thickens slightly (about 5 minutes). Remove from heat, stir in vanilla and sea salt. Cool to room temperature.
  6. Prepare Frosting: Beat softened butter until light and fluffy. Gradually add powdered sugar, alternating with heavy cream to reach spreadable consistency. Mix in vanilla extract.
  7. Assemble the Cake: Place one cake layer on serving plate. Spread a generous layer of frosting, drizzle some brown butter caramel over it. Top with second layer and frost entire cake smoothly.
  8. Add Caramel Drip and Gold Leaf: Warm remaining caramel to pourable consistency if needed. Slowly drip caramel over cake edges using spoon or ladle. Let set about 10 minutes. Carefully apply edible gold leaf pieces on caramel drips and cake top using tweezers or dry brush.

Notes

Use a light-colored pan to watch butter browning closely. Room temperature ingredients help batter mix smoothly. Avoid overmixing after adding flour to keep cake tender. Warm caramel gently if too thick for dripping. Apply gold leaf with tweezers or dry brush to avoid sticking. Chill frosted cake before applying caramel drip for best results. For gluten-free, use 1:1 gluten-free flour blend with xanthan gum. For dairy-free, substitute almond milk and vegan butter, but flavor will vary.
