Chocolate Cookie
1.
Weigh all materials
2.
Flour, cornstarch and cocoa powder are mixed and sieved (I don’t have low-gluten flour, so I use flour and starch instead. If there is low-gluten flour, use 85 grams of low-gluten flour instead of mixing flour and starch)

Add powdered sugar and salt after the butter is softened

6.

7.

10.
Stir it with a spatula until there is no dry powder
11.
Squeeze it into the baking tray with the eight-tooth decorating nozzle
12.
Put it in the preheated oven, middle level, upper and lower heat, 170 degrees, about 20 minutes until the edges slightly change color.
