Instructions
Making the Cookie Dough
Preheat the oven to 160°C (320°F/140°Fan). Sift the flour and baking powder and set aside.
Chop up your chocolate bar roughly into little bits to form irregular shaped chocolate chips. Set aside.
Chop up the butter roughly into 3-4 bits and melt in the microwave oven in 30 second bursts, stirring in between. Do this until it's completely melted.
Add the sugar and stir thoroughly for about 10 seconds.
Add the vanilla and mix well.
Tip in the the flour and mix well with a wooden spoon.
Finally, stir in the chocolate chips. You will end up with a fairly dry chocolate chip cookie dough.
Baking the Cookies
Form little golf size balls with the cookie dough. Use a cookie scoop if you prefer.
Place your dough balls on the baking sheet and flatten them ever so slightly.
Bake in the pre heated oven for 15-18 minutes until the edges are just beginning to brown. You can do both trays at the same time, the top tray will be done faster. Take them out of the oven and leave them to cool for about 10 minutes on the trays, then transfer them onto a cooling rack to cool completely.Store in an airtight container for up to 5 days.
