Heat oven to 350°F. Prepare two 8-inch cake pans. (Use butter and flour, line with parchment, or spread GOOP)
(Make sure milk and eggs are room temperature.)Pour milk (I used whole), egg whites, and extracts into a medium bowl and stir with a fork until blended.
Mix cake flour, sugar, baking powder, and salt in the bowl of electric mixer at slow speed. (just to sift and incorporate ingredients) Add butter, cut into cubes and continue beating on low for about 1-2 minutes.
Allow cake to cool in pan about 5 minutes then carefully flip onto a cooling rack to room temperature.
