Preheat oven to 180 C / Gas 4. Lightly grease a loaf tin.
Sift the flour, bicarbonate of soda, baking powder, salt, cinnamon and cloves together in a large bowl. Stir in the oats. Beat the butter, sugar and vanilla together in a mixing bowl until light and fluffy. Stir in the eggs until well blended. Mix in the apple sauce, walnuts and raisins. Stir in the flour mixture just until moistened. Pour mixture into prepared loaf tin.
Bake in preheated oven until a skewer inserted in middle comes out clean, about 55 minutes. Take care not to over-bake. Cool 5 minutes in tin before turning out on a rack to cool completely.
