Set your oven to 350°F (175°C) and line two baking trays with parchment paper.
02 -
In a stand mixer bowl, whip the butter and sugar together until the mix is fluffy and light. This should take about 3 minutes.
03 -
Pour in the bourbon along with the salt and stir just until the mixture is smooth.
04 -
At a low speed, add the flour and combine until a dough forms.
05 -
Put about a quarter of the dough into a piping bag fitted with a large rosette tip. Twist the end of the bag to push the dough down toward the tip. Let the bag rest on a warm oven for a minute to soften the dough slightly.
06 -
With the slightly warmed dough, pipe tight rosettes onto the lined baking trays. Since they won't spread much when baking, you only need a bit of space between them. Repeat with the other batches of dough.
07 -
Put the trays of shaped dough into the freezer for about 30 minutes or until they're completely hardened.

Once frozen, bake the cookies until the edges turn a pale golden color, which should take roughly 23 minutes.
