Ingredients:
- 3 cups (375g) cake flour
- 1 ½ cups (300g) granulated sugar
- 1 tbsp (12g) baking powder
- ½ tsp (3g) salt
- 1 cup (225g) unsalted butter, softened and cubed
- 4 large eggs (200g), room temperature
- 1 cup (240ml) whole milk, room temperature
- 2 tsp (8g) vanilla bean paste
- 1 tsp (5ml) lemon juice
- 2 cups (450g) unsalted butter, softened
- 6 cups (720g) powdered sugar, sifted
- 3 tbsp (45ml) heavy cream
- 1 tsp (5ml) vanilla extract
- ¼ tsp (1g) salt
Instructions:
- Preheat oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper.
- Combine cake flour, granulated sugar, baking powder, and salt in a mixing bowl.
- Add cubed butter and mix on low speed until the texture resembles coarse sand.
- Beat in eggs one by one, then stir in whole milk, vanilla bean paste, and lemon juice. Mix only until smooth.
- Divide batter evenly between the two pans and bake for 30–35 minutes until a toothpick inserted in the center comes out with a few moist crumbs.
- Cool cakes in the pans for 10 minutes before transferring to a wire rack to cool completely.
- Level the cakes using a serrated knife to remove the domes.
- Place the first layer on a plate, spread a thick layer of buttercream, and top with the second layer.
- Apply a thin crumb coat of frosting over the entire cake and chill in the refrigerator for 30 minutes.
- Using the cake trim, stack two small squares of cake, frost with black buttercream, and add a chocolate stick and yellow frosting tassel to create the graduation cap.
