01 - In a large mixing bowl, add the Greek yogurt, fresh lemon juice, lemon zest, honey, vanilla extract, and sea salt. Whisk thoroughly until the mixture is smooth and well blended.
02 - If using any optional additions such as chopped fresh mint or white chocolate chips, gently fold them into the yogurt mixture until evenly distributed.
03 - Pour the mixture evenly into popsicle molds, tapping each mold lightly on the counter to release any trapped air bubbles. Insert popsicle sticks into the center of each mold.
04 - Place the filled molds in the freezer and allow them to set for at least 4 hours, or until completely firm throughout.
05 - To unmold, briefly run the outside of each popsicle mold under warm water for a few seconds, then gently pull the popsicle out. Serve immediately.
