Pre-heat the oven to 160°C/140°C fan/Gas 3. Line with baking parchment. Beat the egg and milk together with a fork.
In a saucepan, put the golden syrup, treacle and low fat spread. Melt and make sure everything is combined.
In a mixing bowl, add the oatmeal, flour and ginger, now pour over the syrup mixture, followed by the egg and milk. Mix well until everything is combined.
Pour the mixture into the lined baking tin and put into the oven for 50 mins - 1 hour. Check that the cake is cooked through by using the cake skewer. If it comes out clean, it is ready, if no, then it needs more time.
Once the cake is cooked, remove the oven and leave in the tin to cool.
Cut the cake into slices and enjoy with a nice cup of tea/coffee/hot chocolate.
