Peanut Butter S’mores Bars

When I give these as gifts, they’re gone in a flash! I make them ahead when it’s convenient because they freeze well. You can use M&M's in different colors for holidays year-round. —Julie Wischmeier, Brownstown, IN

    Very simple to make and extremely tasty. I took these peanut butter s'mores to a church dinner and was asked by two people to make them again for next Sundays lunch. Thanks for an easy dessert recipe.

    I couldn't find just peanut butter cookie dough so I used Nestle Toll House Ultimate Chocolate Peanut Butter Deluxe w/peanut butter cups, chips & chocolate chunks and it was delicious!!! This recipe is a keeper and will make often! Thank you for sharing this wonderful and simple recipe!!!

    The peanut butter cookie base wasn't that flavorful, and then it was just some marshmallows and chocolate chips thrown on top. They're pretty cookies, but didn't find the taste to be anything out of the ordinary.

    My son-in-law took these to work to share, and his coworkers keep asking him for more! Rich and delicious- I had to use a bag mix of peanut butter cookie dough tho - couldn't find refrigerated.
