3. Add flour, baking powder, baking soda and salt to bowl and whisk to mix.  Set aside.
4. In a larger bowl, beat softened butter, and sugar until pale yellow and fluffy.  Then mix in vanilla and lemon zest.  Add the egg and mix very well.
5. Alternate mixing the buttermilk and the dry ingredients into the butter-sugar bowl.  Do this in 2-3 batches for both the dry ingredients and the buttermilk and mix thoroughly each time.  The batter will be slightly thick.
