Preheat the oven to gas mark 6 (200 degrees Celcius) and line a cake tin with cupcake cases.
Cream the margarine and sugar together in a large mixing bowl until soft and fluffy. This should not take long if you are using soft margarine.
Sieve in the flour and add in the eggs. Mix the ingredients together until everything is well combined and smooth.
At this point you can add the cinnamon. Add the desired amount of cinnamon one teaspoon at a time, mixing until you are satisfied with the colour of the mixture. About 1-2 teaspoons gives you the result in the photo.
Add in the raisins or dried fruit and briefly mix to incorporate.
Using two tablespoons, spoon one tablespoon of the mixture into each cupcake case. Divide the mixture equally between all cases, scraping clean each spoon.
Bake in the oven for 15-20 minutes until golden brown. These cakes taste light and fluffy hot and denser when cool.
