In a medium mixing bowl, mix together yogurt, maple syrup, vanilla extract, cinnamon, and salt. Mix in one or a combination of desired add-ins. Alternatively, divide yogurt mixture into a few bowls and stir a different filling into each bowl.

Fill ices molds almost to the top and place sticks in. You can make a few of each flavor, or you can layer a few flavors on top of one another. You can also position fruits, like strawberry slices, against the sides of the molds instead of mixing them directly into the yogurt.

Freeze for a few hours, or until hardened. Popsicles are best if you wait five minutes for them to defrost slightly before eating. If necessary, run the popsicles under water to help ease them out of the molds.
