My kids were enormous fans of these peanut butter s’mores bars.

They could have easily disappeared in just one day if I had allowed it. As it was they only lasted 3.

These cookie bars are so easy to make. No special equipment required. You can mix up these bars with just a bowl and spoon.

A soft and chewy, peanut butter, graham cracker crumb, and chocolate chip bar cookie is baked, and then topped with mini marshmallows and more chocolate chips. Broil for a couple minutes to toast the marshmallows and the cookie bars are done.

These peanut butter s’mores bars are delicious. You will love them!

Can I use natural peanut butter in these peanut butter s’mores bars?

I haven’t tried this recipe with natural peanut butter, just regular smooth peanut butter. The difference between the two is that natural peanut butter is usually a bit drier and not quite as smooth.

In baking that will translate to drier, more crumbly, baked good. So it can be a noticeable change in peanut butter cookies.

These s’mores bars, however, are very soft and chewy, and I think that natural peanut butter would work well here as a substitute. That being said, I haven’t tried it myself!

Should you refrigerate cookie bars?

It depends on the bar, but these s’mores bars don’t need to be refrigerated. I think the marshmallows would actually go quite tough if they were refrigerated, so I don’t recommend it.

Store these cookie bars at room temperature in an airtight container for up to 5 days.

How to make Peanut Butter S’mores Bars:

  • You don’t need an electric mixer for these bars. Simply stir everything together in a bowl and spread the soft cookie dough in a baking pan.
  • These bars need to cool completely before cutting them. If you try to cut them while they’re still warm, you will have a sticky mess as the marshmallows will not cut well when they’re still warm.
  • The best way to cut these bars is with a long, serrated knife.
  • Store these bars in an airtight container at room temperature for up to 5 days.
