Preheat the oven to 200°C, fan 180°C, gas 6. Place 10 paper cases in a greased 12-hole muffin tin.
In a large bowl, mix together the flour, oats, sugar, cinnamon and bicarbonate of soda. In another bowl, mix together the eggs, yogurt, vanilla extract and sunflower oil. Add the egg mixture to the flour mixture and stir well. Add the raisins and stir in, but be careful not to over-mix.
Spoon the mixture into the muffin cases and bake for 18-20 minutes.
Remove from the oven, then drizzle about 1 teaspoon honey over the top of each muffin. Sprinkle with porridge oats and icing sugar and serve warm.
