1.
Preheat the oven to 375 degrees. Line a cookie sheet with parchment paper and set aside.
2.
Sift together the flour, salt, and baking powder in a medium bowl. Set aside.
3.
In the bowl of a stand mixer, beat the butter on medium speed until it's smooth. Add the sugar, vanilla extract, and lemon zest. Beat until it's well combined.

Add the eggs to the mixer and beat on medium speed for at least one minute.
5.
Reduce the mixer speed to low and slowly add the flour mixture a little at a time.
6.
Stop once the mixture is just blended.
7.
Drop the cookie dough in roughly 1 tablespoon balls onto the prepared cookie sheet. The mounds should be about three inches apart.

Bake until the edges of the cookie reaches a delicate golden brown, roughly 12 - 14 minutes.
9.
Remove the cookies from the oven and allow to cool on the baking sheet for about 10 minutes before transferring to a cookie rack to cool completely.

Repeat until all of the dough has been used.
