Spray a 9-inch square baking dish with nonstick cooking spray and line with parchment paper.
Melt the candy corn in a large bowl over a double boiler, or in the microwave for 1 minute, then stir and return to the microwave at 30 second increments until melted and smooth. Stir in the peanut butter and the ground roasted peanuts. Spread into an even layer in the prepared baking dish and let cool completely until set, about 30 minutes. Use the parchment paper to help you lift the candy out of the baking dish. Cut into 1-by-2-inch pieces using a pastry wheel or pizza cutter.
Line a baking sheet with parchment paper. Melt the chocolate chips in 30 second increments in the microwave or over a double boiler until smooth (see Cook's Note). Dip each piece of candy into the chocolate, using a fork to turn and coat. Let any excess chocolate drip off before placing onto the prepared baking sheet. Repeat with the remaining pieces of candy. Drizzle the chocolate decoratively over the top of the chocolate-coated candy. Let the chocolate cool and set up completely.
If you are using chocolate chips and your chocolate doesn't seem smooth enough, add 1 tablespoon of vegetable oil.
