Making the iced pops: Add yogurt, 1 cup of the blackberries, honey, and basil, if you are using it, to a blender. Blend until everything has turned purple and has a smooth texture.
Filling the molds: Plop a whole blackberry into a frozen pop mold. Pour a bit of the yogurt mixture into the mold. Plop in another blackberry and more of the mixture. Repeat until mold is three-fourths full. Repeat with remaining molds.
Freeze until treats are frozen through, about 1 hour.
