This is a close cousin to a pound cake - the proportions are close, but we use buttermilk for part of the butter content. We also cheat a little bit by adding some baking soda.

|White sugar||440 Gram ((+ extra for the pan))|
|Cake flour||320 Gram|

6.Juice the lemons and then In a cup combine the buttermilk and lemon juice.
7.Add the remaining sugar and the lemon zest to the stand mixer bowl and beat together with the paddle attachment.
