Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking soda, and salt.
In a large bowl, mix the melted butter with the granulated sugar.
Add the brown sugar and mix until smooth.
Add the eggs and vanilla extract. Mix until fully combined.
Add the dry ingredients and stir until a thick cookie dough forms.
Fold in the chocolate chips and chopped chocolate.
Scoop the dough onto the prepared baking sheet, leaving space between each cookie.
Bake for 10 to 12 minutes, or until the edges are set and the centers still look slightly soft.
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a cooling rack.
