Old court records show a Yorkshirewoman was hauled up in 1728 for stealing oatmeal to bake this cake — proof it's been a treasured treat for centuries.
Oatmeal, black treacle, dark sugar and ginger are baked into a dense, sticky cake, then left to mature for a few days so it turns even softer and more treacle-dark. Market stalls in Leeds and across Yorkshire sell it wrapped in squares every autumn, especially around Bonfire Night.
