Step 1

Preheat oven to 350F.

Step 2

In a stand mixer or with electric beaters, cream together the butter, powdered sugar, salt, vanilla extract, and lemon zest until light and fluffy (1-2 minutes)

Step 3

Add the flour, and mix just until the dough comes together. Give it a final stir by hand to make sure everything is evenly incorporated.

Step 4

Using about 1 tablespoon of dough, roll each cookie into a ball and place on an ungreased baking sheet, about an inch apart.

Step 5

Bake for 10-12 minutes. The cookies will still be pale and very soft when they come out of the oven, do not over bake. Allow to partially cool on the baking sheet before gently removing to a rack.

Step 6

While the cookies are still barely warm, roll them in powdered sugar. Give them a second coat when they are completely cool. Note: if your powdered sugar is lumpy, be sure to sift it before coating.
