Peel ripe mango and cut flesh away from pit in large pieces working around the flat oval pit — cut flesh into rough chunks and place in blender jar.
Add plain yogurt, whole milk, and honey to blender with mango chunks.
Blend on high speed until completely smooth and no fibrous pieces or chunks remain — mixture should be vibrant deep golden-orange.
Taste mixture and adjust honey if needed — it should taste intensely of mango with pleasant sweetness and slight tang from yogurt.
Pour mango mixture evenly into popsicle molds filling each one to just below the rim — leave small space at top as mixture expands slightly during freezing.
Tap molds gently on counter to release air bubbles and ensure mixture settles evenly to bottom of each mold.
Insert a popsicle stick into center of each filled mold — use mold lid if available to hold sticks upright — if no lid freeze 45 minutes until surface is just firm enough to hold stick then insert and return to freezer.
Freeze for minimum 8 hours or overnight until filling is completely solid all the way through — do not rush this step.
When ready to dip line a baking sheet with parchment paper and place in freezer to chill.
Place finely chopped white chocolate and sunflower oil together in a microwave-safe bowl.
Microwave on high power in 30-second intervals — after each interval remove from microwave and stir thoroughly — continue until chocolate is completely melted smooth glossy and fluid.
Do not microwave continuously — white chocolate is sensitive to overheating and will seize or scorch without stirring between intervals.
Allow melted chocolate mixture to cool to just above room temperature — very hot chocolate melts bar surface immediately on contact.
To unmold bars run warm water over outside of each mold for 10–15 seconds and pull gently on stick — bar should release cleanly — work quickly and have chocolate ready before unmolding.
Hold each bar by the stick and dip into melted white chocolate submerging fully — tilt bowl to ensure complete coverage.
Lift bar out of chocolate and allow excess to drip off for 5–10 seconds rotating slowly for even coating — the cold frozen bar will cause chocolate to begin setting within 30–60 seconds.
Place each dipped bar immediately on chilled parchment-lined baking sheet.
Place baking sheet in freezer immediately and freeze until chocolate shell is completely set and hard — approximately 15–20 minutes.
Serve immediately once shell is fully set or store individually wrapped in parchment paper in freezer.
