Butter Cookies (Beginner Version)

Weigh all the ingredients and put them into containers for later use; this will save a lot of preparation time and reduce confusion during the process.

Place the butter in a bowl and let it soften at room temperature in advance, then use a spatula to press and mix continuously until smooth, and add the powdered sugar and mix evenly.

Add the egg whites in three batches, stirring well each time before adding the next batch, and finally add a few drops of lemon juice and mix evenly.

Sift in the cake flour.

Mix with a spatula until smooth.

Put it into a piping bag and cut a small opening at the tip.

Line the baking tray with parchment paper in advance, and pipe the batter onto the tray vertically, about the size of a button.

Preheat the oven to 170 degrees in advance, bake for 15-20 minutes, and take out when the surface color is appropriate. Note: The specific baking time varies depending on the size of the cookies.

Place the baked cookies on a wire rack along with the baking pan to cool. Once completely cooled, they become exceptionally crisp. Store in an airtight container.
