This is recipe for the lemon pound cake I am making that falls. I am using self rising flour instead of the AP. Any ideas why it falls? I have made it several times with the same results. I did add 1/2 tsp baking soda this time thinking more leavening agent might help. I also added a tsp of lemon extract. Could that be the cause?
