Instructions
Preheat the oven to 350°F (177°C). Grease three 9-inch cake pans, line with parchment paper rounds, and grease the parchment.
Whisk together cake flour, salt, baking powder, and baking soda in a bowl. Set aside.
Beat the butter and sugar together on high speed until creamy, about 3 minutes. Scrape the bowl as needed.
Add the eggs, egg whites, and vanilla extract, and beat until combined, about 2 minutes. The mixture may look curdled.
On low speed, gradually add the dry ingredients, mixing just until combined. With the mixer on low, add buttermilk and mix until fully incorporated.
Divide the batter evenly between the prepared cake pans. Bake for 23-26 minutes, or until a toothpick inserted into the center comes out clean. Allow cakes to cool completely in the pans on a wire rack.
For the frosting, beat the butter on medium speed until smooth, about 2 minutes.
Add confectioners' sugar, milk, vanilla, and salt. Beat on low speed until combined, then increase to high and beat for 2 minutes until fluffy.
Once the cakes are cool, level the tops with a serrated knife. Discard or crumble the tops over ice cream.
Place the first layer of cake on a cake stand or plate. Spread about 1 and ½ cups of frosting over the top. Top with the second cake layer and frost again. Finish with the third layer, and cover the cake with the remaining frosting.
Chill the cake in the refrigerator for at least 1 hour to help it hold its shape when slicing.
Notes
This cake is perfect for birthdays and celebrations, with its light, airy texture and rich flavor. The frosting can be customized with sprinkles or any other decoration of your choice.
