Instructions
Preheat oven to gas 4/180°c/350°f.
Line a loaf tin with baking paper; or you could use a silicone one, with no need to line.
Beat together the low fat spread and sugar until light & fluffy. Mix in the eggs one at a time, then add the salt & spices.
Fold in the flour and baking powder, bit by bit, then mix in the carrot, raisins, and orange zest & juice.
Pour the mixture into the loaf tin and bake for 40-45 minutes, or until a metal skewer inserted comes out clean.
Leave to cool in the tin for a few minutes, then remove to a wire rack.
To make the frosting, mix together the quark, orange zest and mixed spice (and sweetener if you wish).
Once the cake is cooled, spread the frosting over the top, sprinkle a little zest, cut into slices, and enjoy!
