Chewy marshmallow-peanut popcorn bars

These sweet, salty, and peanut buttery treats make a great after school treat or make-and-take dessert for any causal get-together! Here, old-fashioned popcorn balls get reimagined into bars simplifying the prep and eliminating the need to quickly shape the warm mixture into balls. They’re also less messy because you can use a spatula to press them in the pan. The addition of oat bran adds extra crunch giving this nostalgic recipe a grown-up twist, yet it still has massive kid appeal. You can enjoy these immediately or cover and store them at room temperature up to a day or two ahead of time.
