I have a question about the recipe "Lemon Velvet Sheet Cake" from Jessie Sheehan. The recipe online is different from the recipe on the video .... which one is the correct recipe? (For instance the on site recipe says to use 1 1/2 cups all purpose flour, and the video recipe says to use only 1 cup... in all, there are 8 ingredient variants between the two recipes given. I really want to make this cake, so which is the correct recipe? Thanks very much!
