First take an oven safe bowl or any cake pan and grease it well with butter and line a parchment over it and grease it with butter too. Set aside.
Take dates and milk in a sauce pan and cook it for 2 mins. Remove it from heat and sprinkle over baking soda, mix well and set aside.
Now take butter and brown sugar in a bowl and cream lightly.
Add in the dates mix and fold gently.
Add in flour, cinnamon and salt. Mix well.
Spoon this into the pan and bake it for 30 to 40 mins. Insert a toothpick to check whether the cake is done or not.
Remove it from oven and set aside cool for 10 mins.
Now invert it on a plate, peel off parchment paper.
Slice and serve with butterscotch sauce.
Notes
Due to the large amount of water in it, the cake mixture will appear quite runny compared to a normal cake batter but it will result in a lovely moist pud.
