Make this authentic Yorkshire parkin a day or two ahead for a sticky teatime treat that can’t be beaten.
Preheat the oven to 180C/350F/Gas 4. Line a 15x20cm/6x8in baking tin with greaseproof paper.
In a pan, gently melt the butter (or margarine), golden syrup, black treacle and sugar until combined.
Mix the remaining dry ingredients together in a large bowl.
Add the hot syrup mixture and stir to combine. Add the milk to help loosen the mixture.
Pour into the prepared tin and bake for 35-45 minutes, or until springy to the touch.
