In large mixing bowl, or bowl of stand mixer, beat butter on medium until creamy (about 2 minutes).

Add sugar and beat another 2 minutes.

Add eggs one at a time, scraping down sides and turning mixture with spatula at least once.

Add vanilla extract.

In another mixing bowl, whisk together flour, powdered cocoa, baking soda and salt.

With mixer on low speed, slowly add dry ingredients to butter mixture until blended, about 45 seconds; add chocolate chips and continue to mix until blended.

Drop or roll about a tablespoon of dough onto parchment paper lined cookie sheet.

Bake at 375 F for about 10 minutes.
