I have to make a cake for someone that absolutely loves the WASC cake that is on this site. She now wants me to make a cake that is as close in texture to this cake but wants a butter cake. I think I can do this, but I'm so unsure of the results. I'll substitute a yellow cake mix for the white, melted butter for the oil, whole eggs for the egg whites and butter flavor for the almond extract. Can anyone offer any opinions or advice? Can butter be substituted for oil? Will the whole eggs be too much liquid? Thanks so much
