The English oatmeal based Parkin cookie/cake varies in texture and style and may be thin or thick, cookie or cake-like. This 1913 Five Roses Cook recipe uses coarse oatmeal and eggs and results in a cake-like version.
Yorkshire Parkin
1 1/2 pounds coarse oatmeal
1/2 pound lard
1/2 pound cooking sugar
2 teaspoons mixed spice
1 pound Five Roses flour
1 pound molasses
2 teaspoons ground ginger
1 teaspoon baking powder
Juice of 1 l3 lemon
3 eggs
Milk to stiffen
Mix well and bake in a slow oven in dripping tin. (American version would be a grease cannister? Does any one have an idea for a substitute cooking utensil? Coffee can?)
