- 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.
