Ingredients:
- 330g cake flour, sifted
- 300g granulated sugar
- 1.5 tsp baking powder
- 0.5 tsp baking soda
- 1 tsp fine sea salt
- 225g unsalted butter, softened and cubed
- 4 large eggs, room temperature
- 240ml full-fat buttermilk, room temperature
- 2 tbsp vanilla bean paste
- 1 tbsp neutral oil
- 450g unsalted butter, slightly cool (for buttercream)
- 600g powdered sugar, sifted
- 3 tbsp heavy cream
- 1 tbsp vanilla bean paste (for buttercream)
- 0.5 tsp fine salt
Instructions:
- Preheat your oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper for a clean release.
- In a stand mixer fitted with a paddle attachment, combine the cake flour, granulated sugar, baking powder, baking soda, and salt. Mix on low speed for 30 seconds to aerate and distribute ingredients.
- With the mixer remaining on low, add the 225g of cubed butter one piece at a time. Continue mixing until the mixture resembles coarse sand with no large butter chunks remaining, effectively coating the flour in fat to minimize gluten development.
