- 2 cups cake flour*
- 2 teaspoons baking powder
- 1 cup (2 sticks) unsalted butter, soft
- 1 1/2 cups Imperial Sugar Extra Fine Granulated Sugar
- 8 large egg yolks at room temperature
- 3/4 teaspoon salt
- 1 tablespoon vanilla extract
- 2 teaspoons lemon zest
- 3/4 cup buttermilk, at room temperature
*Spoon & Sweep method: Use a spoon to fill measuring cup with flour until required amount is obtained. Scooping measuring cup directly into flour bag will firmly pack flour resulting in too much flour required for recipe.
- Preheat oven to 350°F.
- Butter and flour two 8-inch (9 inch pans are ok also) baking pans and set aside. (Fitting a round piece of parchment paper on bottom of baking pan is recommended for easy removal of cake.)
- Sift together flour and baking powder and set aside.
- Mix butter until very creamy and smooth. Add sugar and mix until light and fluffy. Add one egg yolk at a time and mix at least 30 seconds between each.
- Add salt, vanilla extract and lemon zest.
- Add one third of flour and mix until combined. Add half of buttermilk and mix until smooth. Add another one third of flour and mix smooth. Add remaining buttermilk and once combined add remaining flour.
- Divide batter into the pans and place in oven and bake for 25-28 minutes until center of cake bounces back when lightly pressed with a finger or until an inserted toothpick comes clean.
- After 5 minutes turn upside down on plastic food lined surface and allow to cool completely before frosting, about 1 hour.
