Preheat the oven to 170 degrees centigrade/Gas Mark 3
Line a square baking tin with parchment and grease the paper or it will stick!
Mix together the flour, sugar, oats and ginger in a bowl and make a well in the centre
Gently melt together the spread, syrup and treacle (do not let it boil) and pour into the well
Sprinkle the bicarbonate onto the syrup mix and then sprinkle the lemon/vinegar over that. The bicarbonate will fizz and bubble. Pour the milk over the top and mix to form a very wet and sloppy batter
Pour into the prepared tin and bake for 25-40 minutes, until golden, risen and a knife cones out clean
Once cool, cut into cubes.
