Line a baking sheet with aluminum foil or wax paper.
Insert a popsicle stick into each halved bananas. Place the yogurt in a shallow bowl, or in individual shallow bowls if using more than one flavor. Place the toppings in another shallow bowl, or in individual bowls if using more than one kind.
One at a time, cover the bananas first in the yogurt, then dip them in your topping of choice, rolling to coat. Place on the prepared baking sheet and repeat until all the bananas are coated. Freeze until firm, at least 1 hour. If not eating right away, you can wrap each banana pop in aluminum foil and keep frozen.
