Preheat your fan oven to 160 degrees c

Prepare a 20cm square tin (I use a silicone one, but a lightly greased and lined tin is perfect).

in a large saucepan, place the butter, syrup, treacle and brown sugar and heat until the butter has melted and the sugar has dissolved.

Put the dry ingredients in to the pan and mix well before adding the milk and egg.

Place in prepared tin and bake for 45 to 50 minutes or until a metal sewer comes out of the centre clean.

Transfer to a wire rack in the tin to cool

Once cold turn out and coot before wrapping in greaseproof paper and storing in an airtight tin.
