Combine the Greek yogurt, vanilla extract, and honey in a small bowl.
Put approximately half of the yogurt mixture into a second bowl. To one bowl, add the cocoa powder and mix to combine.
Flavor each yogurt to taste with additional cocoa, honey, or vanilla as desired.
Spoon the vanilla yogurt, cocoa yogurt, and cherry pie filling in alternating patterns into each popsicle mold. Only spoon in approximately 1-2 Tablespoons at a time to get many different layers throughout the popsicles. Tap the popsicle mold on the counter to help the ingredients settle and remove gaps if necessary.
Continue filling each mold until there is approximately 1/2 inch gap at the top.
Insert the popsicle sticks into the center of each mold. The thickness of the yogurt should make them easily stand up. (I do not use the lid of the mold because often times the popsicle sticks slant enough that it makes it difficult to remove).
Freeze the popsicles until completely set, at least 4 hours.
To remove from the mold, run hot water over the outside of the popsicle molds. Wiggle the sticks until you can pull the popsicles out. Only run under hot water briefly each time to prevent melting as much as possible.
