Method
Create the Cookie Foundation
- In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until fully combined and glossy.
- Whisk in the egg, egg yolk, and vanilla extract until the mixture is smooth.
Combine Dry and Wet Ingredients
- In a separate bowl, whisk together the flour, cocoa powder, espresso powder, baking soda, and salt.
- Gently fold the dry ingredients into the wet ingredients with a spatula until just combined. Fold in the chocolate chips and chunks.
Chill and Bake
- Cover the bowl and chill the dough for at least 30 minutes.
- Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper. Scoop rounded tablespoons of dough onto the sheets, leaving 2 inches of space between them.
- Sprinkle with flaky sea salt. Bake for 11-13 minutes, until the edges are set but the centers are still soft. Let cool on the baking sheet for 5 minutes before moving to a wire rack.
Notes
Don't Skip the Chill: Chilling the dough is essential for thick, fudgy cookies and to prevent spreading.
Use Chopped Chocolate: Using a chopped baking bar creates those beautiful, large melted pools.
Bang the Pan: For more pronounced cracks, you can carefully drop the baking sheet on the counter once or twice midway through baking.
Reserve Some Chocolate: Press a few extra chocolate chunks into the tops of the dough balls before baking for a bakery-style look.
