Altered ingredient amounts.
I increased all the quantities by 25% and baked in a slightly bigger tin - 25cm by 25cm. I also increased the amount of white chocolate by another 20grams or so and made sure the chunks were not too small. Very moreish. - 02 Nov 2010
Very tasty! Loved it with following modifications. I didn't want greasy so I upped the flour to 160g and used 2 eggs, cooked at 180C for 40 minutes - keep getting requests for this and will now be a regular favourite. - 06 Nov 2013
