Prepare a parchment-lined baking tray or set out a foam block or cups filled with uncooked rice to hold the pops upright while they set.
Insert one lollipop stick into the center of each marshmallow, pushing it in far enough to hold securely without piercing through the top.
Place the crushed graham crackers on a shallow plate or bowl so they are ready for coating.
Add the chocolate chips to a microwave-safe bowl. Microwave in 20-second intervals, stirring well after each interval, until smooth. If the chocolate seems too thick for dipping, stir in 1 teaspoon coconut oil or vegetable shortening until it reaches a smooth, pourable consistency.
Working with one marshmallow at a time, dip it into the melted chocolate, coating about two-thirds of the marshmallow. Gently tap off any excess chocolate.
Immediately roll the chocolate-coated marshmallow in the crushed graham crackers until evenly coated.
Place the coated S'mores Pops on their sides on the prepared parchment-lined baking tray, leaving a little space between each pop. If desired, drizzle with melted white chocolate and decorate with festive sprinkles or crushed peppermint candies before the chocolate hardens.. Refrigerate the pops for 5 minutes until the chocolate is firm and serve.
