I really don't have time to research and decide. I am super indecisive about this. I usually just make sheet cakes, but we are trying out some decorations and flowers. I will do 3 layers 9-inch. I don't have a go to except for a chocolate one. I just need something basic. I don't have cake flour. Also I have American type buttercream. What should I frost with? We want a traditional looking icing to show off the flowers and decorative pearl sixelets. I do have cream cheese. I could make some fancier buttercream. Help me decide. None of the genius cakes are right.
