Yield Serves 8
Prep: 30 minutesCook: 20 minutesTotal: 50 minutes

A big buttery chocolate chip cookie frosted with chocolate frosting.


  • 115 grams (1/2 cup or 1 stick) unsalted butter, softened
  • 135 grams (3/4 cup) brown sugar
  • 1 teaspoon vanilla extract
  • 1 large egg
  • 175 grams (1 and 1/4 cups) plain flour or all purpose flour 
  • 1/2 teaspoon baking soda
  • 1 teaspoon cornflour or cornstarch
  • 1/4 teaspoon salt 
  • 150 grams (1 cup) milk or dark chocolate chunks

Chocolate frosting

  • 115 grams (1/2 cup or 1 stick) unsalted butter, softened
  • 375 grams (3 cups) icing sugar or powdered sugar
  • 20 grams (1/4 cup) cocoa powder
  • 50 grams (1/4 cup) full fat cream cheese, room temperature
  • 12 tablespoons full fat whole milk
  • Funfetti sprinkles, optional


  1. Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Grease and line an 8-inch round springform cake pan with parchment or baking paper.
  2. In a large mixing bowl, beat the butter and sugar with an electric mixer until combined. Add vanilla and egg and continue to beat until soft and creamy. Sift in flour, baking soda, cornflour and salt. Gently fold until dough starts to come together.
  3. Throw in chocolate and fold through. Place all the dough into your prepared tin and press down and spread out as even as possible. Press a few extra chocolate chunks in the top.
  4. Bake for 18 – 20 minutes or until golden brown. Try not to overcook as you want it soft and gooey in the middle. Leave to cool completely.
  5. In a large mixing bowl, beat the butter until creamy and smooth and then sift in half the icing sugar. Add a tablespoon of milk to help loosen up the mixture. Add the rest of the icing sugar and cocoa powder and continue to beat. Add cream cheese and beat until smooth.
  6. Add an extra tablespoon of milk if the frosting is too thick. It should be nice and creamy but thick enough to hold its shape. Pipe the icing onto the cake and then cut and serve. Add sprinkles, if desired.


Chocolate frosting: There is more than enough chocolate frosting to decorate this cookie. You could add more frosting to the cookie or bake a second cookie. Or just enjoy the leftover frosting. You can halve the frosting recipe but I always like there to be too much rather than too little.
