Muffins can almost be made any flavour that takes your fancy, but here are some of my favourites:
Blueberry
1 cup of blueberries (frozen work well). For Apple and Blueberry also add 1 apple, peeled and finely chopped.
Raspberry and white chocolate
1 cup of raspberries (again, frozen are great) and ½ cup white chocolate pieces
Banana chocolate chip
Add ½ cup milk chocolate chips to the dry ingredients and 2 ripe bananas mashed into the wet ingredients
Apricot cream cheese
Drain a 330g can of apricot halves, reserving the juice. Dice the fruit and stir through the dry ingredients. Replace the milk in the wet ingredients with the juice of the apricots, made up to the required ¾ cup with milk if necessary. When filling the muffin cases, only half fill them then add a tablespoon of cream cheese to each one. Fill to the top of the muffin case with the remaining muffin mix.
Spiced apple
2 apples, peeled and finely diced, ½ tsp ground cinnamon, ¼ tsp ground nutmeg, ¼ tsp ground cloves
Pear and walnut
2 pears, peeled and finely diced, ½ cup chopped walnuts, ¼ tsp ground cinnamon
For savoury muffins
Simply reduce the sugar quantity as stated and add 1 cup grated cheese to the dry ingredients. Then the possibilities are endless for the combinations of other savoury ingredients to add - red onion, bacon, chives, chilli, rosemary, paprika, chorizo, capsicum, grated zucchini, tomato - fresh or sun-dried, ham, cubes of camembert or blue cheese all work very well.
