Another from Nigella Lawson's Feast cookbook. You can use granola or muesli interchangeably here. There was more batter than I usually get for a 12 muffin recipe so I kept filling up the cups more and filled them nearly to the top with some batter still left over but not much. The muffins did not rise much so I guess this was the right thing to do. These are tasty little treats that are also good for you. Enjoy!
