Base : Place all dry ingredients in a bowl and combine . melt the margarine\butter and pour into the dry mix and combine well .

press firmly into a lamington tin and place in oven at 200'C for 10-15minutes ,checking at the 10minute mark . when cooked bring out the oven and place aside to cool a little while you make the filling . leaving the oven on ready for the next step .

Filling : mix the golden syrup and condensed milk together . melt the butter\margarine and pour into the milk mix and mix well to combine all .

Pour the milk mix onto the base and place back in the oven for a further 10-15minutes or until set but not hard . take out of the oven and set aside whilst you make the topping .

Topping : combine icing sugar ,cocoa and a little warm water to make a slightly runny consistency so to be poured over the slice to top . spread over evenly and leave to cool and near set ,so that you can mark the slice before setting properly,and then to be sliced later .

I don't cool in the fridge to set . but it's up to you .

also you can use melted chocolate for the topping . mum never does she uses the icing mix .
