Blueberries, Raspberries, Blackberries, Strawberries... Oh MY! I made this recipe when the wild raspberries were everywhere at our cottage. I have made them with each type of berry you can think of. I've also subbed the oil for applesauce, which goes quite well with strawberries. I'm making myself hungry just typing this now. :) Please let me know how many muffins this yielded for you. I have the jumbo cups and it turns out different every time.
