Preheat oven to 350 degrees and line a cookie sheet with parchment paper.
In a large bowl, beat butter until light and fluffy, about 1 minute. Add in both granulated and brown sugars, beating until well combined.
Add in the egg and vanilla extract, and beat until combined.
Add in salt, espresso powder, and baking soda; mix until combined.
In a separate bowl, mix flour and cocoa powder together. Slowly incorporate the dry ingredients into the wet ingredients, mixing until combined.
Add in white chocolate chips, semi-sweet chocolate chips and Buncha Crunch Baking Bits; mix until combined.
With a medium cookie scoop (about 2 Tbsp of dough per cookie), scoop the dough and spread evenly on the cookie sheets, about 2 inches apart.
Bake for 14-15 minutes, or until cookies are done.
Enjoy!
