These Healthy Sourdough Discard Banana Carrot Muffins are everything you want in a wholesome bake: moist from mashed banana and shredded carrot, gently spiced with cinnamon and nutmeg, and sweetened naturally with maple syrup and raisins. The sourdough discard adds a subtle tang and helps create a tender crumb, while whole wheat flour gives them a hearty, satisfying texture. Topped with a crunchy oat-carrot streusel, they’re perfect for breakfast, snacks, or market baskets.
