A Bill Granger recipe from the November issue of the Observer Food Monthly magazine. 

Makes approx 30

150g unsalted butter, softened
165g firmly packed-brown sugar
1 egg, lightly beaten
2 tsp vanilla extract
125g plain flour
1 tsp baking powder
a pinch of salt
200g rolled oats
140g white-chocolate chunks
85g dried cranberries

Preheat the oven to 180°C/gas 4 and line three baking trays with baking parchment. Cream the butter and sugar together until pale and creamy. Add the egg and vanilla and beat until smooth.

Sift the flour, baking powder and salt together. Add the oats, chocolate and cranberries and stir together. Add to the creamed mixture and stir together well.

Roll small tablespoons of the mixture into balls and place on the baking trays. Flatten the balls with a fork dipped in flour.

Bake for 12-15 minutes until pale golden. Leave to cool on the trays for 5 minutes before transferring to a wire rack to cool completely.
