These Lime Popsicles are low calorie (just 23 calories), low sugar (1.6g) and low carb (2.5g)... and they are so easy to make!We have used a zero calorie all-natural simple syrup, but you could use regular simple syrup, honey, or agave instead if you prefer. Special Tip: Make these Key Lime Pops by using key lime juice (11-12 key limes) and by crumbling 2 gram crackers over the tops before adding in the popsicle sticks.
