Peel bananas, cut away any bruises. Puree using a food processor or blender.
Fill each mold with banana puree. Fill to 1/4 inch from the top to allow room for stick and expanding during freezing. Place lid on molds, insert sticks. Make sure sticks are straight in each cup (this helps when removing the lid after they are frozen).
Freeze for 2-4 hours or overnight.
When ready, melt chocolate and coconut oil in the microwave (30 seconds at a time, stir in between). This should only 1 to 1 1/2 minutes.
Remove each popsicle from it's mold. Dip in chocolate and tap to remove excess chocolate. Let chocolate harden before placing in a bag and back in freezer or enjoy immediately.
