I read about this recipe on allrecipes. You can read about it here:http://allrecipes.com//Recipe/to-die-for-blueberry-muffins/Detail.aspx It sounded so good and it had such great reviews that I had to give it a try. It's wonderful! I made mine into 12 muffins instead of 8. The crumb topping adds a nice sweetness and a bit of a crunch. I loved the cinnamon,too. And look at those blueberries inside!
I added more berries than it called for...one can't have too many berries can they? I don't think so!
