Since my sister is allergic to eggs, I've been trying to find banana muffin recipes that are egg-free. This one is an adaptation of my original sour cream banana bread recipe. It seems like I can just increase the ratio of sour cream, and then use brown sugar and a higher baking temperature to increase the darkness of the muffins and decrease the stickiness of the muffin tops. These muffins came out so moist and full of banana flavor, you would not miss the eggs at all.
P.S. I had tried baking at 350 instead of 375F and it turns out that you do need the higher temperature. The muffin tops turn out sticky and progresses to gummy the next day if baked at the lower temperature.
