Line a small baking dish with aluminum foil, parchment, or plastic wrap.  Make sure you have this ready to go.

In a microwave safe bowl, melt the candy corn.  Approximately 30 seconds (50-60 seconds, max).

Have your peanut butter waiting on a big spoon and the second you take the candy corn out of the microwave, stir in the peanut butter.  If it hardens up on you too fast, place mixture back into the microwave for 10 seconds or so, until you can stir it to be smooth.

Take your smooth mixture and put it into your baking dish, pushing it down with a spoon or your hands.  Work quickly.  Place this into the freezer.

Next, melt your chocolate chips.  If you want more/less of a chocolate layer, use more/less chips.

Remove the baking dish from the freezer, pour melted chocolate over it.  Place in freezer and allow to set up for 10 minutes or so, slice & enjoy.
