Method
- Heat the oven to 350°F (175°C). Grease and flour two 8-inch (20 cm) round pans and line the bottoms with parchment paper.
- Whisk the flour, baking powder and salt together in a medium bowl until evenly mixed.
- Beat the butter and sugar with a hand mixer or stand mixer until pale and fluffy, about 3 minutes. Beat in the egg yolks, the whole egg and the vanilla until smooth.

- Add the dry ingredients in three additions, alternating with the milk, beginning and ending with flour. Mix just until smooth — do not overbeat.
- Divide the batter evenly between the prepared pans and smooth the tops.

- Bake for 25–30 minutes, until a toothpick in the center comes out clean and the tops spring back lightly when pressed.
- Cool the cakes for 10 minutes in the pans, then turn them out onto wire racks to cool completely before frosting.

- Frost with chocolate, vanilla or fruit frosting once the layers are completely cool, then slice and serve.

Notes
Use room-temperature eggs and milk so the batter blends smoothly, and do not overbeat once the flour goes in — overmixed batter bakes up dense instead of tender.
