Grease and line a loaf tin with baking parchment.
Sift the flour into a large bowl, add the bicarbonate of soda, ginger and mixed spice.
Add the sugar and mix well.
Add the treacle, milk, oil and eggs and mix until the mixture is smooth.
Pour into the loaf tin and bake for 45 minutes in the centre of the oven.
Test that a knife or skewer comes out clean when pushed into the loaf to ensure it is cooked.
Leave to cool in the tin for about ten minutes then turn out onto a wire rack.
