Ingredients in Peanut Butter Popcorn
- Popcorn - our favorite popcorn to use is plain freshly popped popcorn. Microwave popcorn and bagged popcorn can be used, but won’t be as crisp and fresh as freshly popped popcorn. Plus, they usually have added salt and other ingredients.
- Butter - you can use salted or unsalted butter depending on your flavor preference.
- Sugar - you will need white granulated sugar for this recipe.
- Corn Syrup - corn syrup or Karo syrup helps to keep the peanut butter caramel soft and prevents the sugar from crystallizing while it cooks. If you want to avoid corn syrup, you could try substituting honey.
- Water - you’ll need just a little tap water to cook the peanut butter mixture.
- Marshmallows - I recommend using mini marshmallows because they melt quicker. If you only have large marshmallows you could chop them up first.
- Peanut Butter - the best peanut butter to use for Peanut Butter Popcorn is regular creamy peanut butter. Don’t try and use the natural varieties because they separate and won’t work as well for recipes like this one.
How to Make Peanut Butter Popcorn
- Pop the popcorn. Place air-popped popcorn into a large bowl being careful to remove the unpopped kernels. Set aside.
- Cook the peanut butter sauce. In a large nonstick saucepan over medium heat, melt the butter, then add the sugar, Karo syrup, and water. Bring to a boil while stirring and cook until the syrup mixture reaches 235-240 degrees F on a candy thermometer (about 4-5 minutes).
- Stir in the marshmallows and peanut butter. Remove from heat, add the marshmallows, and stir until they are completely melted. Next, add the peanut butter and stir again until smooth.
- Add to the popcorn. Pour the peanut butter coating over the popped corn and stir until it is completely coating the popcorn.
- Let cool. Spread the peanut butter popcorn onto a parchment lined or lightly greased baking sheet and allow to cool completely at room temperature.
- Serve. Once cooled, break into smaller pieces and serve in individual cups or a large bowl. Store in an airtight container at room temperature for up to 5 days. Enjoy!
Peanut Butter Popcorn Balls
To turn this recipe into Peanut Butter Popcorn Balls, follow instructions 1-4 above, then allow the mixture to cool just until it is cool enough to handle. Then, shape into 3-4” balls using your hands. You may want to wet your hands a bit between popcorn balls so that the mixture doesn’t stick.
Let the Peanut Butter Popcorn Balls cool completely on a baking sheet, then transfer to individual cellophane bags or serve as is.
Frequently Asked Questions
I prefer to use either white or yellow air-popped popcorn because it is as fresh as it gets and doesn’t contain any extra butter, salt, or added flavors. You could use microwave popcorn or even bagged popcorn if you want, but try and find kinds with the least amount of added ingredients as possible.
You sure can! All you need to do is follow instructions 1-4, then let the mixture cool enough to handle before shaping into your desired sized popcorn balls. You may want to wet your hands slightly between shaping so that the mixture doesn’t stick.
If you find that your peanut butter mixture is so thick that you can’t even mix it into the popcorn, most likely it was cooked to too high of a temperature. Make sure to check the temperature as it cooks using a candy thermometer. Once the mixture reaches 235-240 degrees F, remove it from the heat immediately and add your marshmallows.
