Preheat oven to 300F and prepare baking sheet using parchment paper or baking mat.

In a mixing stand, add the cream of tartar, salt, and egg whites and beat it at high speed until soft peaks form. Then gradually add the granulated sugar 1 tablespoon at a time, while the mixer is on high speed. Now once stiff peaks form, turn off the mixer and then sift the unsweetened cocoa powder in the bowl.

Next, you are going to fold this in and then fold in the mini chips.

Using a piping bag, pipe the cookies onto parchment paper.

Bake for 40-45 minutes, then remove from pan and cool on a cookie rack.
