Step 1

Preheat oven to 350°F (176°C). Line the baking sheet with parchment paper.

Step 2

In a mixing bowl, beat butter, powdered sugar until creamy, light and fluffy. Add in the vanilla extract and stir well. Fold in the potato starch, cake flour and mix well until a soft dough is formed.

Step 3

Divide the dough into 2 rounds. Use your palms to shape them into small balls. To make the pattern on the cookies, use a fork and press gently onto the top of the round cookies. Dip the fork in water after each press to prevent the cookie dough from sticking to the fork.

Step 4

Place baking sheet in the bottom part of the oven. Bake for about 10 minutes or until the cookies turn very slight brown. Remove from the oven and let cool for about 5 minutes. Dust some powdered sugar over cookies before serving.
