Ingredients
- 1 1⁄4 cups whole milk
- 2 1⁄2 tbsp. vanilla extract
- 3 cups flour
- 2 tsp. baking powder
- 1 ⁄2 tsp. kosher salt
- 1 lb. unsalted butter, softened, plus more for greasing
- 3 cups sugar
- 5 eggs
- 1 (1-lb.) box confectioners' sugar
Preparation
Step 1
Heat oven to 325°. Bring 1 cup milk to a simmer in a 1-qt. saucepan; remove from heat and add 2 tbsp. vanilla. Whisk flour, baking powder, and salt in a bowl; set aside. In another bowl, and using an electric hand mixer, beat 3⁄4 lb. butter and the sugar until combined. Add the eggs, one at a time, mixing well after each addition. With the motor running, slowly add dry ingredients until combined. Drizzle in milk mixture until a smooth batter forms. Pour batter into a greased 9"-round, 2 1⁄2"-deep cake pan; bake until a toothpick inserted into center of cake comes out clean, 1–1 1⁄2 hours. Let cool slightly, then invert onto a wire rack; let cool completely and transfer to a cake stand.
Using an electric hand mixer with clean beaters, beat remaining milk, vanilla, and butter in a bowl until combined. With the motor running, slowly add confectioners' sugar until a smooth frosting forms; spread evenly over cake. Chill 20 minutes before serving.
