Heat the oven to 180°C/160°C fan/Gas Mark 4. Line a 12 hole muffin tin with paper muffin cases. Mix the orange juice, agave nectar, oil and egg together in a large jug. In a large bowl combine the flour, 80g Special K and raisins. Fold in the orange juice mixture then spoon into the muffin cases. Scatter with the remaining Special K. Transfer to the oven and bake for 20-25 minutes until golden and a skewer comes out clean. Meanwhile mix the yogurt and orange zest together and serve with the muffins. Topping alternative Why not try a mixture of yogurt with fresh sliced strawberries and blueberries? Freezing and defrosting guidelines Bake according to the recipe but stop before adding decoration. Allow to cool completely. Wrap well in clingfilm and tin foil (to prevent freezer burn) and freeze for up to 3 months. If you wish to add icing or decoration, add it after the baked goods have fully defrosted and are at room temperature.
