Tips:
The powdered sugar can be beaten with sugar by yourself. You can also choose other flavors for the taste of cookies. You can choose your favorite flavor. Because everyone squeezes differently in size and thickness, so the temperature and time are only a reference. You can adjust the temperature and temperature according to your own oven. Time, the batter is relatively dry and can be squeezed in two small bags at a time. The decorating nozzle I use is taken in the whole box, so there is no specific model. You can buy a nozzle with 18 teeth or more by yourself, or you can use any nozzle you have at home, but the pattern is different.
