In a mixing bowl cream together the butter and confectioners sugar on high until it is light and fluffy. Depending on your mixer this will take 3 to 5 minutes.

Stir in the egg, milk and vanilla until well combined.

Add the salt and flour and mix well until a soft dough forms. The cookie dough shouldn't be wet or crumbly. If it's to wet add a little more flour and if it's crumbling and not sticking together add a little more milk.

Put the dough into your spritz cookie press and press your cookies out onto the baking sheets.

Bake at 350F for8 to 10 minutes until the edges have turned a light golden brown.
