Ingredients
Method
Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
Melt dark chocolate and butter together until smooth, stirring frequently.
In a separate bowl, whisk eggs, granulated sugar, demerara sugar, and vanilla until slightly thick and pale.
Mix the melted chocolate into the egg mixture until combined.
Sift in flour, cocoa powder, baking powder, and salt, then fold gently.
Stir in chocolate chips.
Scoop batter onto baking sheet, spacing cookies apart.
Bake for 10–12 minutes until tops are set and slightly crackled.
Cool on the baking tray before transferring.
Notes
Use good-quality chocolate for best flavor. Do not overbake—cookies should look slightly underdone in the center. Store in an airtight container for up to 3 days.
