Preheat oven to 350*F
Line 3 baking sheets with parchment paper and set aside.
In a large bowl beat together the softened butter and the icing sugar until it is light and fluffy.
Next beat in the egg, vanilla, lemon flavoring and lemon peel until combined for about 1 minute.
The dough will look somewhat curdled because of the alcohol in the lemon extract or lemon flavoring and that is o.k. Do not over beat.
Add the flour, pinch of salt and beat until combined.
Transfer the dough, one cup at a time to a pastry bag with a star tip (I used the 1M tip)
Alternately, you can also use a cookie press.
Pipe dough in a circular motion starting with a center and working your way outward forming a rose shape. (Space the cookies 1 inch apart on the cookie sheet)
Bake at 350*F for 8 to 10 minutes until the bottom is light golden brown. Let cool completely.
