Baked granola bars have become a staple in many households, offering a convenient and nutritious snack for individuals of all ages. These bars are made from a mixture of rolled oats, nuts, seeds, and dried fruits, baked together to create a crunchy and flavorful treat. However, one of the most common questions asked by consumers is how long do baked granola bars last? Understanding the shelf life and storage requirements of these bars is essential to ensure they remain fresh and safe to eat.
Factors Affecting Shelf Life
The shelf life of baked granola bars depends on several factors, including ingredients, storage conditions, and packaging. The type and quality of ingredients used can significantly impact the bars’ shelf life.
