Preheat the oven to 350°F (175°C) and prepare your baking pans.

In a bowl, combine cake flour, baking powder, and salt.

In a separate bowl, cream together unsalted butter and white sugar until fluffy.

Add eggs one at a time, mixing well after each addition.

Stir in vanilla extract and pink gel food coloring.

Alternate adding the flour mixture and buttermilk, starting and ending with flour.

Pour batter into prepared pans and bake until a toothpick comes out clean, about 20 minutes.

Allow cakes to cool before frosting with cream cheese mixture.

To make the frosting, beat together softened butter, cream cheese, vanilla extract, and powdered sugar until smooth.
