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!

  • Method: oven
  • Cuisine: american

Ingredients

  • 1/4 cup unsalted butter, room temperature
  • 1/2 cup natural peanut butter
  • 3/4 cup brown sugar
  • 1 egg, room temperature
  • 1 cup all purpose flour
  • 3/4 cup graham cracker crumbs
  • 1/2 teaspoon baking soda
  • 3/4 teaspoon salt
  • 2/3 cup chocolate (we used chopped up Hershey’s bars, but any chocolate will work!)
  • 2/3 cup mini marshmallows

Instructions

  1. Preheat the oven to 350°F and line a square pan (9 x 9 or 8 x 8 will both work), with parchment paper. Set aside.
  2. In a stand mixer fit with the paddle attachment, beat together the butter and peanut butter until homogenous. Don’t over mix.
  3. Add the brown sugar and mix well. Scrape down the bowl and add the egg and vanilla extract. Mix until combined.
  4. Scrape down the bowl and add the flour, graham cracker crumbs, baking soda, and salt. Mix until combined and no streaks of flour remain.
  5. Add the marshmallows and chocolate pieces and fold once or twice to distribute throughout the batter. Transfer the batter to the prepared baking pan and pat into an even layer.
  6. Bake for 20 to 30 minutes or until set on the edges and a knife inserted into the middle comes out mostly clean.  Allow to cool before slicing into 16 pieces. Enjoy!

  1. You mention vanilla extract in the text and instructions but there is no measurement listed in the ingredients?

  2. recommendations for making without a stand mixer? can you do with a hand mixer? if so, do any of the instructions change?

    • Hi Sarah! You could absolutely make these with a hand mixer. Just use the hand mixer to whip up the butter, peanut butter and sugar and follow the directions!
