Snickerdoodle Banana Bread with Cinnamon Sugar Swirl

Snickerdoodle Banana Bread takes everything you love about classic banana bread and adds a thick layer of cinnamon sugar in every bite. Very ripe bananas, brown sugar, vegetable oil, and sour cream keep the loaf soft and tender, while a generous sprinkle of cinnamon gives it that warm, bakery-style flavor. It’s baked in a simple 9 x 5 loaf pan and finished with a crackly cinnamon sugar topping that makes it hard to stop at one slice.
