Instructions

Cookie instructions

  • Preheat the oven to 175°C (350°F).
  • Line and spray a 20cm (8 inch) springform tin.
  • In a large bowl for your stand mixer cream together the butter, brown sugar and caster sugar for 3-4 minutes. You should scrape the side of the bowl often. You want a light and creamy texture. (see note)
  • Add the egg, egg yolk and vanilla and mix for 1 minute.
  • In a separate bowl combine the flour, cornflour and baking powder and give it a whisk together.
  • Add flour mix to your stand mixer and mix for 1 minute on low until just combined.
  • Remove bowl from your stand mixer and stir through your add ins like chocolate chips.
  • Spread cookie dough in to the prepared can tin.
  • Bake for 25 minutes but start checking at 20 minutes with a skewer. Different ovens will affect the total cooking time. Mine took 25 minutes for the skewer to come out clean. (see notes)
  • Set aside to cool for 10 minutes then run a flat knife around the outside to loosen the cookie. Leave it in the tin to cool completely.
  • Remove from tin and place on serving plate ready to decorate.

Chocolate Buttercream

  • Cream butter for two minutes in a stand mixer.
  • Add cocoa powder and icing sugar and beat for 1 minute.
  • At this stage you will need to start adding your cream (or milk). Start with one tablespoon and mix until combined. If you feel that the icing is too think add some more and mix again. Continue to do this until you reach the desired consistency. I used 2 tablespoons for mine.
  • Decorate as desired.

Notes

  1. If you don't have a stand mixer you can use a hand mixer, it might just take you extra time to get the mixture creamed.
  2. I used white and milk chocolate chips but you could use anything here.  I think it would be nice with roasted macadamia nuts and white chocolate. Or you could replace the chocolate chips with M & Ms.  
  3. I prefer to use cream in the icing but milk will work fine. The cream just makes the icing more delicious I think.
  4. If you feel that the cookie is getting too dark you can cover with foil until its finished cooking.  I didn't need to do this however.
