In a large mixing bowl, mix butter, powdered sugar and vanilla extract with an electric mixer or in a stand mixer with a paddle attachment until smooth.
Add in cornstarch, flour and salt.
You can do the same steps with your hands too. Just make sure you combine everything well.
Cover and chill the dough for half an hour.
Preheat the oven to 350F (175C).
Line a baking sheet with parchment paper.
Make mini balls from the dough and place on the baking sheet leaving about 1-inch space.
Gently press a fork on the cookies to give them a nice shape. (See how to make it in the video below)
Bake for 13 minutes or until the edges are very slightly golden.
Remove from the oven, let them sit on the baking sheet for 5 minutes. Then transfer onto a wire rack to cool them completely.
Sift powdered sugar on them and serve.

NOTES
Don’t skip the chilling step. Otherwise, the cookies will flatten when baking.
These cookies do look pale when they are baked, so don’t tend to over-bake them.
After removing the cookies from the oven, make sure they sit on the baking sheet for 5 minutes. Then transfer on a wire rack to let them cool completely.
