Method
Preparation
- Beat the softened butter with white sugar and brown sugar in a large bowl until the mixture is light and fluffy.
- Add the eggs one at a time, then mix in the vanilla extract until fully combined.
- In a separate bowl, whisk together the flour, cocoa powder, baking soda, salt, and espresso powder.
- Gradually mix the dry ingredients into the butter mixture, then add the milk and 1 1/2 cups of chocolate chips, stirring until the dough just comes together.
- Cover the dough and refrigerate for at least 3 hours or overnight.
Baking
- Preheat the oven to 350°F / 175°C and prepare baking sheets with parchment paper.
- Scoop the chilled dough onto the lined baking sheets, spacing the portions apart.
- Place the remaining 1/2 cup of chocolate chips on top of the dough portions and add flaky sea salt if using.
- Bake for 12–15 minutes, until the edges are set while the centers stay soft.
- Let the cookies cool on the baking sheets for 5 minutes, then move them to a wire rack to finish cooling.
Notes
Chilling the dough helps reduce spreading and creates thicker cookies with softer centers.
