Step 1

Preheat the oven to 300F degrees and line cookie sheets with parchment paper or baking mats (like silpat)

Step 2

In a large bowl beat the butter and powdered sugar until very fluffy and aerated (at least 5 minutes, but you should do 7)!

Step 3

Mix in the flour, cornstarch, salt and vanilla extract.

Step 4

Dust your hands with cornstarch, then form the dough into balls about 2 teaspoons in size.

Step 5

I then pressed that down and used a cookie cutter for a fun shape. (OPTIONAL)

Step 6

Quicker method is to take those balls and press slightly down with a fork to flatten slightly. I preferred this, but it does take a lot of time.

Step 7

Bake for 12-16 minutes, or until the tops look set. They will not look brown. The smaller and flatter you make your cookies, the less time to bake.

Step 8

Add optional granulated sugar or sprinkles to top.
