Basic cake recipe

Basic vanilla cake
Ingredients
* 2 sticks unsalted butter, room temperature,
* 2 1/2 cups all-purpose flour,
* 1/2 teaspoon baking powder n baking soda
* 1 teaspoon salt
* 1 1/2 cups sugar
* 2 large eggs plus 3 large egg yolks
* 2 teaspoons pure vanilla extract
* 1 cup low-fat buttermilk/ yogurt
* Whipped Frosting

Directions
Preheat oven to 350 degrees. Butter and flour two 8-by-2-inch cake pans. In a medium bowl, whisk flour, baking powder, baking soda and salt.
In a large bowl, using an electric mixer beat butter and sugar until light n fluffy. With mixer on low, beat in eggs and yolks, one at a time. Beat in vanilla. Alternately beat in flour mixture and buttermilk, beginning and ending with flour mixture; mix just until combined.
Divide batter between pans; smooth tops. Bake until cakes pull away from sides of pans, 32-35mins. Let it cool 10mins before taking out.
Place one cake, bottom side up. Tuck strips of parchment paper underneath. Using an spatula or table knife, spread top with Whipped Frosting. Top with remaining cake; frost top, then sides. (Store unfrosted cakes at room temperature up to 1 day. Once frosted, serve within a few hours.)
