This recipe for chocolate chip cookies is really easy to follow and makes delicious, slightly chewy cookies. You can also give the cookies your own twist using whatever you fancy. For example, try replacing the dark chocolate chips with white chocolate, raisins, mini marshmallows, the choice is yours! I've even tried using finely chopped crispy smoked bacon!! This recipe uses an egg so probably best not to eat the cookie dough raw and when baked will keep in a tin for a week, if they last that long.
