Melt chocolate in a microwave-safe glass or ceramic bowl in 15-second intervals, stirring after each interval, 1 to 2 minutes. I microwaved for a total of 90 seconds, but every microwave is different. Once the chocolate is almost totally melted (but you can see a few chunks of chocolate), stir continuously until smooth. Set aside to cool for 1 to 2 minutes.
Lay a sheet of parchment paper on a work surface or baking sheet.
Add the corn nuts to the melted chocolate and stir until evenly coated. Spoon clusters of the chocolate-corn nut mixture onto the parchment paper, about 1 heaping tablespoon each.
Allow to set at room temperature or place in the refrigerator for faster setting. Once set, serve immediately or keep in a cool place for up to 2 weeks.
