Ingredients
Method
- Preheat oven to 350°F (175°C). Butter two 8-inch round cake pans and line with parchment.
- Beat butter and sugar on medium-high until light and fluffy, about 3 to 4 minutes.
- Mix in eggs and egg yolks one at a time, then add vanilla.
- Combine flour, baking powder, and salt. Add to butter mixture in three batches, alternating with buttermilk, mixing just until combined.
- Divide batter into pans and bake 28 to 32 minutes. Cool completely on a wire rack.
- For the buttercream, beat butter until creamy, then gradually add sugar, cream, vanilla, and salt. Beat until fluffy. Frost cooled cake layers and serve.
Notes
If the frosting tastes a little too sweet, a tiny pinch of salt balances it. The cake layers freeze beautifully unfrosted—just wrap them in plastic and foil.
