Ingredients
Method
- Cream butter and sugars until light and fluffy. Add eggs and vanilla. Blend until combined.
- Whisk flour, cocoa powder, baking soda, salt, and espresso powder (if using) in a separate bowl.
- Gradually add dry ingredients to wet ingredients and mix until almost combined. Stir in milk and 1 1/2 cups of chocolate chips. Add more milk if needed.
- Cover and chill the dough for at least 3 hours (or overnight).
- Soften dough at room temperature for 10-20 minutes, then preheat oven to 350°F. Line baking sheets with parchment paper.
- Scoop dough into balls and place on baking sheet. Press remaining chocolate chips onto tops and sprinkle with sea salt (if using).
- Bake for 12-15 minutes or until edges are set and centers are slightly soft.
- Cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely. Serve and enjoy!
Notes
For extra chewy cookies, slightly underbake them. Store in an airtight container for up to 3 days.
