Preheat the oven to 350 degrees F. Grease and flour 3 (8x2) round pans.
In a medium bowl, combine the cake flour, baking powder, baking soda, salt, and lemon zest). Whisk for 30 seconds to combine and set aside.
In another bowl, combine the Limoncello, milk, lemon juice and lemon extract. The milk will take on a thick look - the lemon juice will be turning the milk into buttermilk
In the bowl of your mixer, add the softened butter and softened cream cheese. Mix until smooth.
Gradually add the sugar and mix at medium speed for 2 to 3 minutes
Add eggs one at a time, mixing until the yellow of the yolk disappears
With the mixer on low speed alternately add the flour mixture and the liquid mixture, beginning and ending with the flour mixture (3 additions of dry mixture and 2 additions of wet).
Divide the batter between the pans.
Bake at 350 degrees F for 22 to 25 minutes or until a tooth pick inserted into the center comes out clean or with just a few crumbs attached. Let cool for 5 - 10 minutes in the pans then then turn out.
This recipe makes approximately 8 cups of batter. Works well for cupcakes (they bake with no dome). Bake cupcakes at 350 degrees for 18 to 20 minutes. Can also be baked in a 9x13 pan.
