I make these Peanut Butter S’mores Sandwich Cookies when you and I want all the flavors of a campfire s’more—graham, chocolate, and toasted marshmallow—wrapped inside a soft, chewy peanut butter cookie. The cookies themselves are loaded with peanut butter and graham cracker crumbs, so they taste like peanut butter cookies and graham crackers baked into one, then you sandwich them around a gooey marshmallow‑chocolate‑peanut butter filling for the full s’mores effect. They’re perfect for bake sales, potlucks, summer nights, or anytime you’re craving s’mores but don’t feel like lighting a fire.
Why You’ll Love These Cookies
These sandwich cookies stack multiple comfort flavors: salty‑sweet peanut butter, honeyed graham crumbs, melty chocolate, and soft marshmallows. The cookie base is soft and chewy with lightly crisp edges, so it holds the filling without crumbling, and the filling sets just enough that the sandwiches are easy to stack and transport. You don’t need to toast marshmallows or assemble messy s’mores—everything bakes on a simple sheet pan, fills in one bowl, and the sandwiches keep well for parties or lunchbox treats.
