01 - Preheat oven to 250°F. Line a large baking sheet with parchment paper and evenly spread corn twists across the surface.
02 - In a medium saucepan over medium heat, combine granulated sugar, corn syrup, unsalted butter, and salt. Stir occasionally until the butter melts and mixture begins to bubble.
03 - Remove saucepan from heat. Add peanut butter and vanilla extract, stirring until smooth and fully incorporated.
04 - Pour the hot caramel-peanut butter mixture over the corn twists. Using a spatula, quickly fold corn twists until thoroughly coated.
05 - Transfer coated corn twists back to prepared baking sheet. Bake for 20 minutes, gently stirring halfway through for even coating.
06 - Remove from oven and allow popcorn twists to cool for at least 30 minutes before breaking into clusters and serving.
