Scallion Milk Cookies

Chop the green onions and let them air dry.

Cut the butter into small pieces and soften it, then mix in the powdered sugar (with starch) and salt until well combined.

Use an electric mixer at medium-high speed to beat until it reaches a whipped cream-like consistency (scrape down the butter from the sides of the bowl with a spatula and continue to whip evenly) (2-3 minutes in summer).

Add the milk in 3-4 portions and whip (scrape down the sides of the bowl with a spatula in between, then continue whipping evenly). The whipped butter should have a feather-like texture.

Pour in the sifted cake flour, use a spatula to cut and press from the side, and mix well. Add chopped green onions and fold evenly. Preheat the oven to 175 degrees.

Fill a piping bag fitted with a medium five-point star tip and pipe out flower shapes. Place a golden tray on the second-to-last rack of the oven and bake for 15-20 minutes.
