These muffins turned out really nice. The sour cream added moisture and a rich quality that I really liked. I did end up mashing the bananas as I didn't care for the look of the slices/chunks in the batter. As you can see in the photo I made 24 mini muffins and 12 regular size muffins. The kids and their friends polished off about half of them after school so you could say they were a hit. Made for Fall PAC 2009. Thx KissingCook!
