Pre-heat the oven to 180ºC and spray a 1lb loaf tin with Low Calorie Cooking Spray and line with baking parchment.
Bake for 25-30 minutes at 180ºC until golden brown or until the knife comes out clean. Don't be tempted to check it before 25 minutes or the cake will sink!
When the cake is done (to check insert a knife and it should come out clean) remove it from the oven, turn the heat down to 100ºC then pour the lemon syrup over the top of the cake and put it back in for another 10 minutes
