What causes muffins to have poor flavor?

Muffins can have poor flavor due to several factors, including the use of low-quality or stale ingredients, insufficient seasoning, or an imbalance in the recipe's ratiOS of sugar, fat, and leavening agents. Overmixing the batter can also lead to a dense texture, which can negatively impact the overall taste. Additionally, baking muffins at the wrong temperature can prevent proper flavor development, resulting in a lackluster final product.
