Pour peaches with juice into a blender container. Cover and blend 15 seconds or until the mixture is smooth. For first layer, pour the peach mixture into each mold until 1/3 full. (Reserve the remainder for second layer.) Freeze 30 to 60 minutes until slightly frozen.
Meanwhile, add 6 oz yogurt to peach mixture in blender container. Cover and pulse twice until blended. Refrigerate until the first layer is slightly frozen.
For second layer, spoon peach yogurt mixture over frozen layer. Tap the mold gently on the counter to ensure mixture evenly fills the mold. Freeze 30 to 60 minutes until slightly frozen.
For third layer, spoon remaining 6 oz yogurt into each mold, tap gently to ensure even coverage. Place pop cover over each mold (or insert Popsicle® stick into cup.) Freeze 2 to 5 hours or until pops are firm.
To remove the pop from mold, place bottom of mold under warm running water for 2 to 3 minutes. Press firmly on the bottom to release the pop. (Do not twist or pull the pop stick.)
