Peel and slice bananas into thirds or fourths. Put each banana piece on a stick. Making sure they don't touch, wrap your plate or dish with Saran wrap and place in the freezer for 4 hours or overnight.
Melt your chocolate via a double boiler over the stove or in the microwave.
Place on wax paper or foil. Place bananas back into the freezer for 30 minutes and then transfer to a freezer safe container or a ziploc bag until you are ready to eat them.
Dip bananas in chocolate and then into nuts - if you have a kiddo with a food allergy, I'm sure you could do sprinkles.
