Ingredients:
- 2 ½ cups (310g) cake flour
- 1 ½ cups (300g) granulated sugar
- 1 tbsp (12g) baking powder
- ½ tsp (3g) salt
- ¾ cup (170g) unsalted butter, softened
- 3 large eggs (150g), room temperature
- 1 cup (240ml) full-fat buttermilk, room temperature
- 1 tbsp (15ml) pure vanilla extract
- ¼ cup (60ml) vegetable oil
- 1 cup (225g) unsalted butter, softened
- 4 cups (500g) powdered sugar
- 2 tbsp (30ml) heavy cream
- 1 tsp (5ml) vanilla bean paste
- Pinch (1g) salt
Instructions:
- Preheat your oven to 350°F (175°C). Grease the cake pans and line the bottoms with parchment paper.
- Sift the cake flour, baking powder, and salt together twice to aerate the dry ingredients.
- Cream the softened butter and granulated sugar on medium-high speed for 3–5 minutes until the mixture is pale and fluffy.
- Incorporate the eggs one at a time, beating well after each addition until the batter is smooth and creamy.
- Whisk the vanilla extract and vegetable oil into the buttermilk.
- Alternate adding the dry ingredients and the buttermilk mixture into the butter mixture (Dry → Wet → Dry → Wet → Dry), mixing on the lowest speed only until flour streaks disappear.
- Divide the batter evenly between the two prepared pans and bake for 30 minutes or until a toothpick comes out clean.
- Prepare the frosting by beating together softened butter, powdered sugar, heavy cream, vanilla bean paste, and salt.
- Chill the cake and frosting for 2 hours to ensure stability before assembling and frosting.
