Tollhouse cookies

I've read about the name of these cookies, how at the tollbooths on the roads people would stop and buy a drink and a cookie.
This version comes from Hannah Miles' new book 'The big book of cakes and cookies' which has 365 recipes for new cakes and well-loved favourites.
Hannah was a finalist in Masterchef 2007, and has a lovely blog which is on my list of favourite blogs - Hannah's country kitchen.
Here's the recipe:

125g butter
350g plain flour
1/2 tspn bicarb.
2 tspns cinnamon
100g caster sugar
100g soft brown sugar
1 tbspn golden syrup
1 large egg, beaten
100g chocolate chips
100g chopped walnuts

Preheat oven 180C/350F/gas4
Makes 20 cookies

Sieve flour, soda and cinnamon into a bowl.
Melt the butter and syrup in a saucepan.
Add the choc. chips and walnuts and egg to the flour mixture and then add the butter mixture. Mix it all together with a wooden spoon.
Divide the dough into walnut sized pieces and put onto greased baking trays. Make sure you leave a space between each one.
Press the tops down lightly.
Bake for 12-15 mins till golden brown and just firm.
Leave to cool on the trays for a few minutes then put on a wire rest.

My variations
I didn't have any chocolate chips so I broke up a 100g bar of dark chocolate, and I didn't add walnuts.
