Carrot muffins - recipe

Here's the recipe for yesterday's muffins.
It's Weight Watchers that I messed with a bit:

250g self raising flour (that's what the recipe said although I'm sure I used plain as that's what you normally put in muffins)
2tsp baking powder
1tsp bicarb
1/2 tsp salt
110g light muscavado sugar
2 eggs
175ml milk
50g margarine (USE BUTTER IF NOT DIETING!) melted and cooled
225g grated carrot
50g raisins
zest of an orange
1/2 tsp mixed spice

Preheat the oven to Gas Mark 5/190°C/fan oven 170°C. Line a 12 hole bun tin with paper bun cases.
Sift the flour, baking powder, bicarbonate of soda, mixed spice and salt into a large bowl. Stir in the sugar.
In a separate bowl, beat the eggs, orange zest, milk and melted margarine together. Stir in the grated carrots and raisins. Add the wet ingredients to the dry ingredients and stir together until just combined.
Spoon the mixture into the bun cases (they will be quite full). Bake for 18-20 minutes, or until risen and firm. Cool on a wire rack.

They could be iced with a cream cheese frosting to improve them!
