Preheat the oven to 350 degrees. Prepare a large baking sheet with parchment paper.
Using a whisk, stir together the flour, cocoa, baking soda, and salt. Set aside.
In a large mixing bowl, beat butter and sugar until light and fluffy. Add the eggs and vanilla, beating for an additional 2 minutes.
Slowly add in the flour mixture and mix until well blended.
Fold the chocolate chips into the batter.
Using a cookie scoop, portion the dough and drop on the prepared baking sheet.
Bake for 8 to 10 minutes or until the edges are set. Remove the cookies from the oven but allow the cookies to rest for about 2 minutes on the baking sheet before transferring them to a wire rack to cool completely.
Store in an airtight container at room temperature for up to one week.
