Bananas are a fantastic ingredient in toddler cooking, as they are a healthy way of sweetening any recipe without adding refined sugar. Mashed banana can also be used in place of butter or oil to keep cakes and muffins moist.
If your toddler is at the stage where they want to help with everything, have them help out with safe parts of cooking such as rinsing vegetables or mixing ingredients. This encourages a good relationship with food and home cooking.
