Line an 8×8-inch baking dish with parchment paper, leaving enough overhang to lift the filling from the pan later.
Place the candy corn in a large microwave-safe bowl. Microwave on high for 1 minute, then stir thoroughly. Continue microwaving in 15- to 20-second intervals, stirring after each one, just until the candy corn can be stirred smooth. Avoid overheating.
Immediately add the peanut butter to the melted candy corn. Stir until completely combined and smooth. If the mixture becomes too stiff to stir, microwave it for an additional 10 to 15 seconds.
Transfer the filling to the prepared baking dish and spread it into an even layer. Let it cool and set at room temperature for approximately 1 1/2 hours.
Use the parchment paper to lift the filling from the pan. Cut it into approximately 2×1-inch bars with a sharp knife. Gently brush away any loose crumbs.
Place the chocolate chips in a microwave-safe bowl. Microwave for 30 seconds and stir. Continue heating in 15- to 20-second intervals, stirring after each one, until the chocolate is smooth.
Using a fork, skewer or sturdy toothpick, lower each piece into the melted chocolate and turn to coat completely. Allow the excess chocolate to drip back into the bowl.
Transfer the coated candies to a parchment-lined baking sheet. Refrigerate for at least 30 minutes, or until the chocolate is completely set.
Store in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months.
