This is a recipe for 'parkin' as it is called in North England. It is a traditional oat cake that gains flavour from black treacle, brown sugar and ground ginger.
Used different ingredients. Didn't have any oatmeal so used porridge oats. It didn't work - tasted good but texture very odd. - 09 Apr 2011 (Review from Allrecipes UK & Ireland)
worked very well, family loved it, but it only took 30 mins to cook in my fan oven and certainly won't last 5 days! - (recommended storage before eating) - 27 Feb 2013 (Review from Allrecipes UK & Ireland)
