Pop the popcorn kernels using an air-popper and transfer the popped popcorn into a large bowl.
Melt the dark chocolate by placing it in a microwave-safe bowl and heating for 30-45 seconds, stirring once halfway through. Then, evenly drizzle the melted chocolate over the popcorn.
Similarly, melt the peanut butter in a microwave-safe bowl for 20-30 seconds until smooth and drizzle it over the chocolate-coated popcorn.
Gently toss the popcorn to ensure an even coating of chocolate and peanut butter. Serve the popcorn warm for the best flavor experience.
