step 1
Heat your oven to 180 deggrees C, 350 deggrees F, gas mark 4 before you start. Wipe a paper towel in a little margarine. Then grease two baking trays by wiping the paper towel over them. Put the sugar and butter into a large bowl and stir them well. Carry on stirring until you get a smooth, creamy mixture.
step 2
Break the egg into a small bowl and mix it well with a fork. Add the vanilla essence to the egg, then mix it in. Pour the egg into the large bowl and stir it in. Sift the flour through a sieve into the bowl then stir everything well.
step 3
When the mixture is smooth, stir in the chocolate chips. Using a tablespoon, put a heaped tablespoon onto a baking tray. Then make 11 more cookies the same way. Flatten each cookie slightly with the back of a fork.
step 4
Bake the cookies for 10 - 15 minutes. They should be pale golden brown and still slightly soft in the middle. Leave the cookies for a few minutes. Then use a spatula to lift them on a wire rack. Leave them to cool completley.
