Place the small cups onto a rimmed baking sheet. Pour the apple cider into the plastic cups 3/4ths of the way full. Place the baking sheet into the freezer.

Once the cider is a slushy thick consistency (about 1 hour to 1 1/2 hours later), place the popsicle sticks into the middle of each cup. Continue to freeze until solid.

Gently remove the popsicle from the cup.
