Preheat your oven to 325℉ / 163℃
Grab your sifter and cake flour - sift your 3 cups cake flour into a bowl
Add baking powder, salt, and whisk together
Set dry ingredients aside.
In a new, clean bowl add butter, cream cheese and sugar
Cream with mixer until ingredients are well combined, light and pale. (about 5 minutes)
Add eggs one at a time - mixing after each egg
Add vanilla extract and butter vanilla flavoring and mix well
Alternate flour and buttermilk - mixing LIGHTLY after each ingredient - *start with dry ingredients, end with dry ingredients*
In a clean cake pan, spray Baker's Joy or any cake release mixture to entire pan (my grandfather used shortening and flour!)
Fill cake pan with batter. Plop pan on counter to release any air bubbles!
Bake in the oven for 1 hour and check for doneness. Check every 10 minutes until your desired color or until toothpick comes out fairly clean. * DO NOT OVERBAKE. *

DO NOT EAT until completely cooled!! ...it gets better with time!
