This recipe is a tried and tested Chelsea Sugar Chocolate Chip Biscuit recipe. The only thing I did differently, was add M&M’s rather than chocolate chips:
½ cup brown sugar (lightly packed)
½ cup caster sugar (normal sugar works too)
½ tsp vanilla essence
1¾ cups self-raising flour
½ tsp salt
½ cup M&M’s (or chocolate chips / chunks)
Preheat your oven to 180°C conventional or 160ºC fan forced and line two baking trays with baking paper.
Beat butter, sugars and vanilla until pale and creamy. Next add the egg and beat until mixed.
Sift in flour and salt, mix until combined before stirring in the chocolate chunks or chips.
Roll heaped teaspoon sized balls of mixture and place on tray, press down lightly with a floured fork.
Bake for approx. 12 minutes.
