Preheat the oven to Gas Mark 4 or 170 degrees.
In a large bowl, mix together all of the ingredients until they form a smooth batter. I just put all of the ingredients into my KitchenAid and blitzed it!
Grease the doughnut tin well with oil or butter to prevent sticking.
Pour the batter evenly into the doughnut rings (leaving a little space for them to rise).
Bake for between 10-12 minutes until lightly golden.
Remove from the oven and cool on a wire rack.
Make the icing by gradually adding a little water to your icing sugar. You may wish to colour the icing at this point, or create a range of pastel coloured doughnuts.
Dip the doughnuts into the icing, then sprinkle with the vermicelli to create a sprinkled iced ring doughnut.
Leave to set (or put straight into your mouth... Up to you!)
