Preheat the oven to 350 degrees F. Line a baking sheet with parchment paper and set aside.
In a medium bowl, whisk together 1 cup flour, cocoa, baking soda and salt. Set aside.
In a standard mixer, combine the butter, brown sugar, and granulated sugar. Mix until it comes together (about 2 to 3 minutes).
Add half of the 5.9 ounce chocolate instant pudding and mix until combined.
Add the egg and vanilla extract and mix until just combined.
Pour the dry ingredients into the wet ingredients and combine. The dough should NOT be sticky. If it sticks to your finger at all, add more flour until it no longer sticks.
Slowly stir in the chocolate chips. Use a two-inch cookie scoop to scoop out cookie dough and roll into balls. Place on the prepared baking sheet, leaving space in between each cookie dough ball.
Bake in the oven for 10 minutes. Remove and let cool on the pan for 10 minutes before transferring to a cooling rack. Enjoy while warm!
