Greek Yogurt Banana Muffins

"These Greek Yogurt Banana Muffins are light, fluffy, and perfectly sweet. The banana flavor alongside hints of cinnamon with walnuts scattered throughout remind me of the banana nut bread I always have my eye on at the bakery. You’ll also love these muffins because they come together, start to finish, in just 15 minutes and just one bowl. Minimal time, minimal mess, maximum flavor. Make these for a tasty Sunday brunch treat and have the remainder prepped for the week ahead."
