Ingredients:
- 3 cups (375g) all-purpose flour
- 2 cups (400g) granulated sugar
- 1 tbsp (12g) baking powder
- 1 tsp (5g) salt
- 1 cup (225g) unsalted butter, softened
- 4 large eggs
- 1 cup (240ml) whole milk
- 2 tsp (10ml) vanilla extract
- 2 cups (450g) unsalted butter, softened
- 6 cups (720g) powdered sugar, sifted
- 1/4 cup (60ml) heavy cream
- 1 tsp (5ml) vanilla extract
- 1 pinch salt
- 1 tbsp (10g) edible gold luster dust
- 2 tsp (10ml) vegetable oil
Instructions:
- Preheat oven to 350°F (175°C), grease and flour two 8-inch cake pans.
- Cream the butter and sugar until pale and fluffy.
- Gradually add eggs one at a time, followed by vanilla extract.
- Alternate adding the flour, baking powder, and salt mixture with the milk, mixing on low until combined.
- Pour batter into pans and bake for 30-35 minutes until the center springs back. Cool completely.
- Beat the softened butter for 5 minutes until ivory-white and airy.
- Slowly add powdered sugar one cup at a time.
- Mix in heavy cream, vanilla, and salt until the buttercream is velvety and holds a stiff peak.
- Frost the cake in a smooth layer and pipe rosettes or borders using a star tip.
- Refrigerate the cake for 30-60 minutes to set the frosting peaks.
- Combine gold luster dust and vegetable oil in a small bowl to form a thick paste.
- Use a food-safe paintbrush to dab the gold paste onto the edges of the frozen buttercream rosettes.
- Allow layers to dry for 2 minutes before applying a second coat for maximum opacity.
