Preheat oven to 375 F. and line 2 rimmed baking sheets with parchment paper.
In a medium bowl or stand mixer, add all wet cookie ingredients and mix with an electric mixer for about 2 minutes until well combined.
Add in all dry cookie ingredients except chocolate chips and mix again until a cookie dough forms (the dough will be thick and sticky). Then, fold in the dark chocolate chunks and mini chocolate chips.
Transfer cookie dough to baking sheet using a medium cookie scoop and bake at 375 F. for 12-14 minutes until lightly golden. Allow cookies to cool for 5-10 minutes on baking sheet (makes 22 medium cookies as shown in pictures).
Enjoy! Store cookies in an airtight container on the counter for up to a week or freeze for up to 3 months. These cookies will stay soft for days after you make them!
