STEP 1 Preheat the oven to 180°C, gas mark 4

STEP 2 Cream butter and sugars, once creamed, combine in the egg and vanilla.

STEP 3 Sift in the flour and salt, then the chocolate chips.

STEP 4 Roll into walnut size balls, for a more homemade look, or roll into a long, thick sausage shape and slice to make neater looking cookies.

STEP 5 Place on ungreased baking paper. If you want to have the real Millies experience then bake for just 7 minutes, till the cookies are just setting - the cookies will be really doughy and delicious. Otherwise cook for 10 minutes until just golden round the edges.
