Chocolate Glutten-free Cookies

These are my all time favorite cookies. I use to buy these many years ago, but the store stopped making them? Oh well, I searched for a recipe that looked like them, sounded like them etc. I found quite a few...crossing my fingers I tried a mix of them. They were perfect! I'm so excited that they are glutten free on top of it.
Pretty easy and quick.

1 3/4 c powdered sugar
1/2 c cocoa powder
2 tsp cornstarch
1/4 tsp salt
2 egg whites :)
1 c coarsely chopped pecans (opt)

Preheat oven to 300º Line sheets with parchment paper
Mix sugar, cocoa and salt. Gradually add egg whites, stirring with a spoon until mixture forms a thick dough. Add nuts if you're using them. Form dough into balls (Using a small cookie scooper, I got about 18 small balls). Place on parchment lined cookie sheet and bake 16-19 minutes and they are glossy and cracked. Let set up a few minutes on cookie sheet then transfer to wire rack to cool completely.
Store in airtight container.
