Roasting the bananas gives them a deeper, richer flavor.
Preheat the oven to 400°F.
Place on a baking sheet:
Roast until very soft and mushy, about 25 minutes.
Let cool slightly, then peel over a blender container, letting the banana pulp fall into the blender; discard the peels. Add to the blender:
Freeze and unmold as described in Fruit Ice Pops. If desired, to coat the pops with chocolate, prepare:
Transfer the chocolate shell to a tall glass or container. Dip the unmolded pops in the chocolate, either halfway or to cover completely. Alternatively, drizzle the pops with the chocolate. Place the coated pops on a baking sheet lined with parchment paper and freeze solid, then transfer to a zip-top bag to store.
