Preheat your oven to 350°F (175°C) and grease two round cake pans.

In a large bowl, whisk together cake flour, sugar, baking powder, and salt.

In another bowl, beat butter and sugar until fluffy. Add eggs one at a time and mix in vanilla.

Gradually combine the dry ingredients with the wet mixture, alternating with milk or water until just combined.

Divide the batter; dye one half red and leave the other white. Pour into prepared pans and bake for 25-30 minutes or until a toothpick comes out clean.

Let the cakes cool completely before frosting with whipped heavy cream between layers and on top.
