• In a stand mixer or with a hand mixer, cream butter and sugar until light and fluffy, ~3 minutes. Add anise, egg yolk, and milk, beating to combine. In a separate bowl, sift baking powder and salt into flour, then add to wet ingredients, mixing until incorporated. Dough will be sticky but thick.
• Cover the bowl with plastic wrap and refrigerate for 1-24 hours.
• When ready to bake, preheat oven to 350 degrees. Line baking sheets with parchment paper or silicon liners. Set up a station with flour, rolling pin, cookie cutters, and prepared baking sheets.
• Flour your workstation moderately, as well as your hands. Take half of the dough and dust it with flour, knead it into a ball, then roll it out as thinly as possible (or as desired,) dusting with flour sparingly but as needed to prevent sticking. Cut into desired shapes. Transfer to baking sheets, leaving a bit of space between each cookie (they don't spread much at all.)
• Bake for 7-10 minutes, until edges are barely golden (these are very pale finished cookies.*) Remove from oven and cool on pans for 3-4 minutes, then remove to cooling rack with a metal spatula.
• Return scraps to bowl and repeat the steps with the remaining cold ball of dough. Repeat a third time with scraps from first two rounds, being sure not to overwork the dough or add too much flour to it as you work.**

Vanilla Buttercream Frosting

• Combine ingredients in a small bowl and beat until a fluffy buttercream consistency is reached, adding milk or sugar as necessary (I like my frosting fluffy, but you may prefer it thinner.)
• Gently spread frosting on each cookie and decorate with sprinkles as desired. This is a fun project for little ones to help with! Allow cookies to dry overnight before packaging and storing.
