Microwave the peanut butter in the microwave for about 30 seconds until melted. Peel the bananas and insert a stick into one end so that they resemble an ice pop
Dip the banana in the melted peanut butter until fully coated. Once the banana is coated in the peanut butter, roll it in the mixed nuts and then place it in the freezer for a few hours. Once frozen transfer them to a cool bag and eat them within 1-2 hours.
