If you like caramel corn and peanut butter, this crunchy peanut butter popcorn is for you! It is the perfect combination of both and it is delicious. Make some for movie night, game night, or just because.
Preheat oven to 250°F and grease a rimmed baking sheet
Place 12 cups popped popcorn in a large bowl and set aside
In a large saucepan, melt ¼ cup butter over medium-low heat. Stir in ⅓ cup light corn syrup, ⅔ cup light brown sugar, 1 pinch salt and ⅓ cup creamy peanut butter. Cook, stirring frequently until it comes to a low boil. Continue to boil, stirring constantly for 1 minute.
Remove saucepan from heat and stir in the 1 teaspoon baking soda and 1 teaspoon vanilla extract. Be careful as the mixture is really hot and it is going to bubble up quite a bit.
Pour hot peanut butter caramel over popcorn and toss to coat.
Spread popcorn over prepared baking sheet and bake for 45 minutes, stirring every 15 minutes.
Spread popcorn over wax paper to cool. Once cooled completely, store in an airtight container until ready to serve.
