½ cup unsalted butter, softened
-
¾ cup brown sugar
-
¼ cup granulated sugar
-
1 large egg
-
1 teaspoon vanilla extract
-
1 ¼ cups all-purpose flour
-
½ teaspoon baking soda
-
¼ teaspoon salt
For the S’mores Filling

Instructions
1. Preheat the Oven
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
2. Make the Cookie Dough
In a large mixing bowl, cream together peanut butter, butter, brown sugar, and granulated sugar until smooth and fluffy.
Add the egg and vanilla extract, mixing until fully combined.
In a separate bowl, whisk together flour, baking soda, and salt. Gradually mix the dry ingredients into the peanut butter mixture until a soft dough forms.
3. Shape the Cookies
Roll dough into 1-inch balls and place them about 2 inches apart on the prepared baking sheet.
Flatten each cookie slightly with a fork to create the classic peanut butter crisscross pattern.
4. Bake the Cookies
Bake for 10–12 minutes, or until the edges are lightly golden.
Allow the cookies to cool completely on a wire rack.
5. Prepare the Filling
Place chocolate chips and mini marshmallows on the bottom side of half of the cookies.
Sprinkle crushed graham crackers over the filling for that authentic s’mores flavor.
6. Melt the Filling
Place the cookies with filling under the broiler for 20–30 seconds or microwave briefly until the marshmallows soften and the chocolate melts.
7. Assemble the Sandwich Cookies
Top each filled cookie with another cookie and gently press together to create a sandwich.
Let the cookies sit for a few minutes so the filling sets slightly.
Tips for Perfect Cookies
Use creamy peanut butter
It creates a smoother dough and better cookie texture.
Don’t overbake
Soft cookies work best for sandwiching.
Watch the marshmallows closely
They can burn quickly under the broiler.
Add graham cracker crumbs
They provide the authentic s’mores flavor and a light crunch.
