30-Minute Peanut Butter Banana Muffins

These tender, naturally sweet muffins combine the classic flavors of peanut butter and banana with warm cinnamon and a hint of vanilla. Made with banana flour and sweetened with sugar replacement, they offer a moist, satisfying texture that's perfect for breakfast, snacks, or lunchboxes. The addition of almond milk keeps them light while lemon juice adds a subtle brightness that enhances the banana flavor. These muffins are easy to make in one bowl and store well for quick grab-and-go treats throughout the week.
