Combine the orange juice, zest, sugar, 1/2 cup of the yogurt, and vanilla extract in a blender. Blend until thoroughly mixed. To enhance the orange color, incorporate a few drops of orange food dye.
Place a small spoonful of yogurt from the other 1/2 cup into every popsicle mold.
Fill the molds with the mixture, leaving only a little space at the top.
Fill the remaining space in the mold with the remaining vanilla yogurt. Stir the yogurt into the orange mixture in each popsicle mold using a popsicle stick.
Allow to freeze for a period of 3 to 4 hours.
Notes
How To Dislodge Popsicles: To easily remove the popsicles from the molds, run the molds under warm water for a few seconds. The gentle heat will help loosen the popsicles and make them slide out smoothly
Add Fruit Pieces: For an extra burst of flavor and a delightful visual appeal, consider adding small pieces of fresh fruit to the popsicle molds before pouring in the juice and yogurt mixture.
