Prep: 18 minutesCook: 12 minutesTotal: 30 minutes

Rich and gooey chocolate cookies loaded with chocolate and walnuts.


  • 115 grams (1/2 cup or 1 stick) unsalted butter, room temperature
  • 90 grams (1/2 cup) brown sugar
  • 50 grams (1/4 cup) caster sugar or granulated sugar 
  • 1 teaspoon vanilla extract
  • 1 large egg
  • 175 grams (1 and 1/4 cup) plain flour or all purpose flour 
  • 40 grams (1/2 cup) cocoa powder, sifted
  • 1 tablespoon cornflour or corn starch
  • 1/2 teaspoon baking soda
  • Pinch of salt
  • 100 grams (2/3 cup) white chocolate, roughly chopped
  • 100 grams (2/3) dark chocolate or milk chocolate, roughly chopped
  • 50 grams (1/2 cup) walnuts, roughly chopped


  1. Preheat the oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Line two baking trays with baking paper.
  2. In a large mixing bowl, add butter and sugars and beat with an electric mixer on medium speed until combined and creamy. Add vanilla and egg and beat for a minute or so until combined.
  3. Add flour, cocoa powder, cornflour, baking soda and salt, and beat just until a chocolately cookie dough forms. Add chocolate and walnuts and stir by hand.
  4. Scoop balls of cookie dough (approximately 1.5 to 2 tablespoons each) and roll until smooth using your hands. Place cookie dough balls onto the prepared trays, leaving room for the cookies to spread in the oven.
  5. Bake for approximately 10-12 minutes or until no longer wet or gooey. Leave for 5 minutes before carefully transferring to a wire rack to cool completely.


Cocoa powder: I recommend using natural, unsweetened cocoa powder. But you can also use Dutch processed cocoa if you like. 

Cornflour: If you don’t have access to cornflour or corn starch, you can simply leave it out. 

Walnuts: If you would prefer to leave out the walnuts, you can add a different nut, like almonds or macadamias. Or if you want to go nut free, add some extra chocolate instead.
