I have a recipe you might enjoy it's not cookies and not strictly a dessert. This was traditionally made on Guy Fawkes night and is very morish.
Cinder Toffee
500g caster sugar
225g Golden Syrup
2 teaspoons Vanilla Essence
90 ml water
1 tablespoon bicarbonate of soda
Grease 8 in tin and line with parchment paper grease parchment paper.
Put all ingredients EXCEPT bicarbonate of soda into a medium to large heavy bottomed pan.
Bring to the boil, do not stir when colour is golden brown temp 150C remove from heat add bicarbonate of soda and whisk thoroughly. This will bubble up like a volcano so take care the sugar mixture is VERY hot.
Pour into prepared tin immediately and allow to cool completely break into pieces.
Enjoy.
