Line a cookie sheet with parchment paper. Cut each banana in half across the middle. Place a popsicle or lollipop stick into the flat end of each banana piece. Lay these out on the lined tray and freeze until very firm, about 20 minutes.
Meanwhile in a glass measuring cup, combine the chocolate chips and the coconut oil. Place this mixture in the microwave and heat at 30-second intervals, until the chocolate is melted. Stir well to combine. Allow to cool slightly. Alternatively, you can melt the chocolate with the oil in a double boiler on the stove.
Place the toppings on small plates. Place several empty plates nearby.
Remove the bananas from the freezer. Dip each banana in the chocolate mixture and quickly sprinkle on the toppings. Hold the chocolate-dipped banana over the empty plate and sprinkle. The empty plate will catch any over-sprinkle so that you can reuse it on the next banana. Lay each banana back on the parchment-lined tray once coated.
Freeze the bananas again until the chocolate and toppings are firm. Serve or store the bananas in a covered container in the freezer, for up to a week.
Store frozen bananas in the freezer, in an airtight container for up to 1 week. To make frozen banana bites: Freeze banana slices on a tray. Use a toothpick to help you dip in the chocolate and roll in the toppings.Nutritional values are approximate and based on 1 banana.
