This is a great chocolate crackle that does not require copha. You can experiment with various breakfast cereals.
Good combination - but mixture as given was too liquid, so needed to add another 3oz Corn Flakes /Bran Flakes mix. Also added 1 to 2 oz sultanas. Then I had an excellent result - which I hope others will try (made 16). - 22 Jun 2013 (Review from Allrecipes UK & Ireland)
