Wash and dry the apple. Slice it into four thick, round slices, removing the core from each slice.
Gently insert a popsicle stick into the bottom of each apple slice to form a “lollipop.”
Spread about 1 tablespoon of sugar-free peanut butter evenly over one side of each apple slice.
In a microwave-safe bowl, melt the sugar-free chocolate chips in 20-second increments, stirring after each, until smooth.
Dip or spoon the melted chocolate over the peanut butter layer, coating thoroughly.
Place the coated apple pops on a parchment-lined plate and freeze for 5–10 minutes until the chocolate is firm.
Enjoy immediately or store in the refrigerator.
