Wash apples and dry thoroughly. Slice into thin-ish (¼") slices and remove any seeds/stem. Insert popsicle sticks through the bottom. Squeeze lemon juice on both sides, let sit for a minute, then pat dry with paper towel.
Add chocolate chips to a heat-safe bowl. Microwave in 30 second intervals, stirring well between each interval, until completely melted. Optional: add 1 tablespoon coconut oil to thin it out.
Spoon chocolate onto the apple slice and spread until the entire slice is coated. Let excess chocolate drip off, then transfer to a parchment paper-lined tray.
Refrigerate until chocolate is hard. Drizzle caramel and sprinkle nuts or any topping you would like on top.
