In a bowl, combine cake flour, baking powder, & salt..
Give it a stir and set it aside. In your mixing bowl, add butter and sugar. Beat it until nice and fluffy, about 3 minutes – and be sure to scrape the bowl to ensure everything mixes in.
Mix in the eggs, one at a time. Then mix in the vanilla.
Add in half of the flour mixture and mix it in.
Add in the whole milk, then mix in the remaining flour mixture, until it is almost all the way mixed.
Stir it by hand to finish it up so you don’t over-mix the batter.
Scoop the batter into the tins. (When I made these, it actually made 2½ dozen cupcakes)
Bake for 22-24 minutes, or until they test done with the "toothpick test."
Let them cool a bit in the pan and carefully removed them to a cooling rack where they can them cool completely.
