Tips for the best peanut butter s’mores bars

• Use high quality ingredients: If you were making a regular ol’ s’more you’d splurge the extra few bucks on the good graham crackers, Hershey’s chocolate, and the fluffiest marshmallows. These peanut butter s’mores bars are no exception. Reach for the ingredients you’d use if you were making a s’more, and crumble them up into your cookie bars!
• Don’t over mix the batter:The key to gooey, fudgy bars is only mixing until everything is just combined. This is not the time to be beating anything until it’s light and fluffy or over mixing which can cause too much gluten to build up in the batter.
• Under bake them a little:No one likes an over baked cookie and cookie bars are no exception. The marshmallows will help keep these bars ooey gooey, but to get a truly fudgy pb s’mores bar you’ll want to bake them until they’re set on the edges and have puffed up, but are still a bit gooey in the middle. They’ll continue to bake as they cool so nothing will be raw – it will just set up into a perfectly soft cookie bar!

Happy peanut butter s’mores bars eating, sweet thangs!
