Peanut Butter Cookie S’mores

Why I Can’t Stop Making These Peanut Butter Cookie S’mores

I’ve never been a huge s’mores fan. One per summer, and I’m done. But these peanut butter cookie s’mores changed everything. Soft peanut butter cookies replace the graham crackers, and a peanut butter cup stands in for the chocolate bar. The result is a s’more that actually makes me want to eat them all summer long. And since it’s National Peanut Butter Cookie Day, I had to celebrate.

Why You’ll Love These Peanut Butter Cookie S’mores

• Soft peanut butter cookies give you a chewy, sturdy base that beats graham crackers every time.

• They come together in minutes once your cookies are ready, perfect for a quick campfire treat.

Key Ingredients for Peanut Butter Cookie S’mores

• Peanut Butter Cookies, Use soft peanut butter cookies for a chewy, tender base. Homemade or store-bought both work, but homemade often have a better texture.
• Large Marshmallows, Standard large marshmallows are ideal for toasting and sandwiching. They give a nice gooey center when toasted.
• Peanut Butter Cups, Choose your favorite brand, like Justin’s or Reese’s. The creamy peanut butter center melts beautifully when warm.

Kitchen Tools for Peanut Butter Cookie S’mores

• Baking sheet (if using the broiler method)
• Campfire, gas burner, or broiler for toasting marshmallows
• Long skewer or roasting stick (for campfire toasting)
• Spatula (to transfer hot marshmallows)

Tips for Making the Best Peanut Butter Cookie S’mores

When toasting marshmallows under the broiler, keep a close eye on them. They go from golden to burnt in just a minute or two. Place them on a baking sheet and broil for 1-2 minutes, rotating the sheet if needed for even browning. If you’re using a campfire or gas burner, rotate the marshmallow slowly so it browns evenly on all sides. Once you’ve assembled the s’more, press gently so the cookies don’t crack. The soft peanut butter cookies are sturdy enough, but a heavy hand can still break them.

Toasting Marshmallows: Campfire vs Broiler

You have two main options for toasting the marshmallows. A campfire gives a smoky flavor and a more traditional experience. Rotate the marshmallow slowly over the coals for even browning. The broiler method is faster and works well indoors. Place marshmallows on a baking sheet and broil for 1-2 minutes, watching closely. Both methods produce a golden, gooey marshmallow perfect for these s’mores.

Peanut Butter Cookie S’mores Variations to Try

If you want to switch things up, try using dark chocolate peanut butter cups or white chocolate peanut butter cups for a different flavor. You can also use crunchy peanut butter cookies instead of soft for a bit of texture. For a more traditional s’more feel, swap the peanut butter cup for a square of milk chocolate. And if you don’t have a campfire, the broiler method works just as well for toasting the marshmallows indoors.

How to Serve Peanut Butter Cookie S’mores

These s’mores are best eaten right away while the marshmallow is still gooey and the peanut butter cup is melted. Serve them with a cold glass of milk to balance the richness. They also make a great dessert at a backyard cookout or camping trip. For an extra treat, add a scoop of vanilla ice cream on the side.

How to Store Leftover Peanut Butter Cookies

Since the assembled s’mores are best eaten immediately, store the components separately. Keep the soft peanut butter cookies in an airtight container at room temperature for up to 3 days. Marshmallows and peanut butter cups can be stored in a cool, dry place in their original packaging.

How to Freeze Peanut Butter Cookies for Later

You can freeze the baked peanut butter cookies for up to 3 months. Arrange them in a single layer on a baking sheet and freeze until solid, then transfer to a freezer-safe bag or container. Thaw at room temperature before assembling the s’mores. Do not freeze the assembled s’mores, as the marshmallow will become tough and the texture will suffer.
