Sift the cake flour, sugar, baking powder and salt into a large mixing bowl.
Add softened chunks of butter and mix on low for 20-30 seconds. The mixture should be lumpy.
Add the milk and vanilla extract. Mix on medium speed to thoroughly blend the ingredients.
Scrape down the sides of the bowl and add in the eggs ones at a time making sure to combine well before adding each egg.
Divide the batter evenly between the two pans.
Bake until the cakes are golden brown and a toothpick inserted into the center comes out clean, approximately 30-35 minutes.
