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!
