Why This Recipe Works
The secret to nailing the authentic s’mores flavor profile in a baked cookie lies in incorporating crushed graham cracker crumbs directly into the peanut butter cookie dough. This gives the cookies a hearty, rustic structure that complements the ultra-creamy, thickened chocolate-marshmallow filling without turning soggy or overly sweet.

Step-by-Step Instructions
Phase 1: Making the Cookie Dough
- Position an oven rack in the center of your oven and preheat to 350°F (175°C). Line two large baking sheets with parchment paper or silicone baking mats.
- In a large mixing bowl, combine the softened butter, 1 cup of peanut butter, granulated sugar, and packed brown sugar. Beat on medium speed for 2 to 3 minutes until exceptionally light, fluffy, and pale.
- Add the eggs one at a time, beating well after each, then pour in the vanilla extract and mix until fully incorporated.
- In a separate medium bowl, whisk together the all-purpose flour, graham cracker crumbs, baking soda, and fine salt.
- Gradually add the dry ingredients to the wet mixture in three additions, mixing on the lowest speed (or by hand with a spatula) just until the flour streaks disappear.
Phase 2: Baking and Cooling
- Portion the dough into uniform balls using a cookie scoop, placing them 2 inches apart on the prepared baking sheets. Gently press down on each ball with the palm of your hand or a glass bottom to slightly flatten into a thick disc.
- Bake for 10 to 12 minutes, until the edges are set and light golden brown while the centers still look slightly soft and underdone.
- Let the cookies rest on the hot baking sheets for 5 minutes to set structurally, then carefully transfer them to wire racks to cool completely.
Phase 3: Preparing the Filling and Assembling
- In a microwave-safe bowl, combine the ½ cup of chocolate chips and ¼ cup of peanut butter. Microwave in 20-second intervals, stirring vigorously after each, until completely melted, smooth, and glossy.
- Allow the chocolate-peanut butter mixture to cool for 1 to 2 minutes (warm, not hot), then gently stir in the mini marshmallows. Let the filling rest for 5 to 10 minutes so it thickens to a spreadable consistency.
- Turn half of the completely cooled cookies upside down. Place a dollop (1 to 2 teaspoons) of the thickened filling onto the center of each inverted cookie.
- Top with another cookie, right-side up, and press down gently to create a sandwich. Let rest for 30 minutes before serving so the filling sets. Enjoy!
Chef Tips for Perfect Results
Cool Completely Before Filling: Never attempt to fill your cookies while they are still warm, or the heat will melt the marshmallow and chocolate filling completely.
Toast Your Marshmallows (Optional): For an authentic campfire touch, you can briefly pass the mini marshmallows under your oven broiler or hit them with a kitchen torch before folding them into the warm chocolate-peanut butter mixture!
Conclusion
Homemade Peanut Butter S’mores Sandwiches are the ultimate fusion of two legendary treats. Chewy, nutty, sweet, and packed with gooey marshmallow and chocolate, they are guaranteed to steal the show at any gathering!
