Cake flour is finely sifted flour. Sometimes, it's pre-packaged with the baking soda added. If you don't have cake flour, you can use all purpose flour. For every cup of cake flour, use 1 cup minus 1 Tbsp. flour. Oh, our measurements are different! I'd have to look up what it is in grams.

I just added this page for you:

I left out an ingredient on the Bailey's Mascarpone recipe!! Wanted to let you know I changed it on the forum!  You need to also include 1/4 cup plus 2 Tbsp. powdered sugar! Sorry about that!
