Peanut Butter Cookie S'mores Recipe

Earlier this week, I shared my Soft Peanut Butter Cookie recipe. They are the BEST! Well, I took those peanut butter cookies and created the ULTIMATE s’mores. Who needs graham crackers when you have cookies? I don’t think I will ever be able to use graham crackers again. I know they are traditionally used to make s’mores, but you guys, cookie s’mores are WAY better. And today is National Peanut Butter Cookie Day so we HAVE to celebrate!

I like s’mores, but I’ve never loved them. I usually eat s’mores once a summer and call it good. Well, I think I created a monster because I am craving these Peanut Butter Cookie S’mores like crazy! I want to eat them every single day of the summer!

Peanut Butter Cookie S'mores Recipe

You need three key ingredients to make my amazing Peanut Butter Cookie S’mores: peanut butter cookies, marshmallows, and peanut butter cups (I like Justin’s). That’s right, no chocolate bars. Remember, we aren’t doing the traditional s’mores thing. We are mixing it up and making the BEST s’mores you will ever eat! The peanut butter cups are a MUST!

Peanut Butter Cookie S'mores

First, toast your mallow. You can do this outside by the campfire if you are the camping type or you can go “glamping” and toast the marshmallows inside. You can use a gas stove or the broiler. Just watch your mallows closely so you don’t burn them. And if you like them black, go ahead and burn them. I know there is a burnt mallow club out there. I’m not in that club though, I like my marshmallows slightly toasted.

When your marshmallow is toasted, take a peanut butter cookie and put a peanut butter cup on top. I am telling you the peanut butter cup is the way to go! You get chocolate AND peanut butter, so much better than a plain chocolate bar.

Top with another peanut butter cookie and gently smoosh the sandwich together!

The cookies are soft, the marshmallow is ooey and gooey, and the warm, melty peanut butter cup is divine! Yes, it will be messy and sticky, but SO worth it! The combination gets an A+++ in my book!

  • First, make your peanut butter cookies.
  • Next, toast the marshmallows over a campfire or over a gas burner, rotating occasionally until golden brown. You can also use the broiler. Place marshmallows on a large baking sheet and broil until toasted, 1-2 minutes. Make sure you watch them because they will toast quickly.
  • Put a peanut butter cup on the inside of a peanut butter cookie. Place a toasted marshmallow on top of the peanut butter cup. Top with another peanut butter cookie and gently smoosh the s'mores together. Serve immediately.
  • Note-you can use store bought cookies, but I highly recommend my peanut butter cookies. They are the best:) And I've tried them with Justin's milk, dark, and white chocolate peanut butter cups and they are all awesome!
