In a medium bowl, cream the butter, sugar and brown sugar with an electric mixer until thoroughly combined. Add the eggs and vanilla. Mix well.

In a separate medium bowl, combine the cocoa powder, flour, baking soda, salt and instant pudding. Slowly add the dry ingredients into the butter mixture, mixing well. Fold in the baking chips. Chill the dough for about 30 minutes.

Preheat the oven to 350 degrees. Grease your baking sheets with non-stick spray or line with parchment paper. Roll the dough into 1/2 tablespoon size balls. Bake for 8 minutes. Allow to cool for 2 minutes on the baking sheet before removing to cooling rack to cool completely. Store in a covered container.
