3 cups cake flour
1 Tbsp. baking powder
1/2 tsp. salt
16 Tbsp. unsalted butter, at room temperature
2 cups sugar
5 large eggs, at room temperature
1 1/4 cups buttermilk, at room temperature
1 tbsp. vanilla extract
Preheat the oven to 350 F. Line two cupcake pans with paper liners. Set aside.
In a medium mixing bowl, combine the cake flour, baking powder and salt. Whisk together and set aside. Add the butter to the bowl of an electric mixer fitted with the paddle attachment. Beat on medium-high speed for 2 minutes, until light and creamy in color. Add in the sugar, and beat for 2 minutes more. Scrape down the sides of the bowl and beat for one more minute.
Mix in the eggs one at a time until incorporated. Scrape down the sides of the bowl after each addition. Combine the buttermilk and the vanilla extract in a liquid measuring cup. With the mixer on low speed, add the dry ingredients alternately with the wet ingredients, beginning and ending with the dry ingredients and mixing just until incorporated. Scrape down the sides of the bowl and mix for 15 seconds longer.
Divide the batter between the prepared paper liners, filling each about 2/3 of the way full (you will likely have batter left over after filling 24 wells.) Bake 18-22 minutes, or until a toothpick inserted in the center comes out clean. Allow to cool in the pans 5-10 minutes, then transfer to a cooling rack to cool completely. Replace paper liners and bake remaining batter if desired. Frost cooled cupcakes as desired. Makes approximately 30 cupcakes
