Yellow Birthday Cake

I made this cake for a 3year old's birthday. It was fun. 3 layers...for 3 years. I used a simple yellow cake recipe that I found from Martha. I used my own buttercream recipe. The cake was perfect for layers, dense for stacking but moist enough to love

Ingredients

1c  unsalted butter, room temperature

2 1/2c all-purpose flour

1/2tsp baking powder

1/2tsp baking soda

1tsp salt

1 1/2c sugar

2 large eggs

3 large egg yolks

2tsp pure vanilla extract

1c low-fat buttermilk

Method

Preheat oven to 350°. Butter and flour two 8-by-2-inch cake pans, tapping out excess flour.
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 and 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 to 35 minutes. Let cool in pans 10 minutes. Run a knife around edges of pans and invert cakes onto a wire rack. Let cool completely. Place one cake, bottom side up, on a cake stand. Using an offset-spatula or table knife, spread top with Buttercream. Top with remaining cake; frost top, then sides.
