Begin by popping your popcorn according to package instructions. Use an air popper or stove-top method for best results, ensuring no unpopped kernels remain. Transfer the popped popcorn into a large mixing bowl, allowing it to cool slightly while you prepare the sweet coating for your Peanut Butter Popcorn Balls.

In a medium saucepan, combine ½ cup honey and 1 cup creamy peanut butter over medium heat. Stir continuously until the mixture is smooth and well combined, about 2–3 minutes. Carefully add 2 cups of mini marshmallows to the saucepan, continuing to stir until the marshmallows melt completely, forming a glossy sauce that should take about 1–2 minutes.

Once your peanut butter mixture is smooth and gooey, remove it from the heat and quickly pour it over the bowl of popcorn. With a spatula, gently fold the mixture into the popcorn, ensuring each piece is thoroughly coated. This step is crucial for creating cohesive Peanut Butter Popcorn Balls, so be gentle to prevent breaking the popcorn.

Allow the coated popcorn to cool slightly for about 15 minutes, making it easier to handle. Once it's cool enough, wet your hands with water to prevent sticking and scoop out approximately ¼ cup of the mixture. Firmly press it into a ball shape, repeating this process until you’ve formed about 10 equal-sized Peanut Butter Popcorn Balls.

You can enjoy your Peanut Butter Popcorn Balls immediately while they are still warm for a chewy texture, or let them cool completely for a firmer bite. If you're not serving them right away, store the popcorn balls in an airtight container at room temperature for up to a week, ensuring they stay fresh and delicious for your next snack time.
