350g (2 ½ cups) plain / all-purpose flour
¾ teaspoon bicarbonate of soda / baking soda
½ teaspoon baking powder
½ teaspoon salt
230g (1 cup) margarine
130g (⅔ cup) caster / granulated sugar
130g (⅔ cup) dark brown sugar
1 ½ teaspoon vanilla extract
1 cup (170g/6oz) dark chocolate chips
1 cup (170g/6oz) white chocolate chips
- Combine flour, baking soda, baking powder and salt in medium bowl; set aside.
- In a separate bowl beat the margarine with the sugars with an electric mixer or wooden spoon until light and fluffy for about 5 minutes. Beat in egg and vanilla, scraping the sides occasionally. Gradually beat in flour mixture until blended. Stir in the dark and white chocolate chips.
- Spoon the dough onto the baking sheets using a tablespoon or an ice cream scoop. Leave at least 2 inches between each cookie so that they have room to spread.
- Bake for 10 minutes or until golden. Let stand 2 minutes on wire rack; remove from sheets and cool completely.
These cookies are really versatile and you can swap the chocolate for candy or dried fruit and nuts. I've already swapped the chocolate chips for 300g Peanut M&Ms and was VERY happy with the results.
