Ingredients You’ll Need

For the Peanut Butter Cookies:

1 cup creamy peanut butter
1/2 cup unsalted butter , softened
1 cup granulated sugar
1 cup packed brown sugar
2 large eggs
1 teaspoon vanilla extract
2 1/4 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt

For the Marshmallow Filling:

1 package miniature marshmallows (or use homemade marshmallow fluff)

For the Chocolate Topping:

1 cup semisweet chocolate chips
1/4 cup heavy cream (or milk for lighter chocolate)

Step-by-Step Instructions

Step 1: Make the Peanut Butter Cookies

Preheat your oven to 350°F (175°C) . Line baking sheets with parchment paper.
In a large mixing bowl, beat the peanut butter , butter , granulated sugar , and brown sugar together until light and fluffy.
Beat in the eggs one at a time, followed by the vanilla extract .
In a separate bowl, whisk together the flour , baking soda , and salt . Gradually add the dry ingredients to the wet ingredients, mixing until fully combined.
Roll the dough into balls (about 1 tablespoon each) and place them on the prepared baking sheets. Flatten slightly with a fork dipped in sugar for crisscross patterns.
Bake for 10–12 minutes , or until lightly golden around the edges. Let the cookies cool completely before assembling.

Step 2: Prepare the Marshmallow Filling

Melt the marshmallows in a microwave-safe bowl in short bursts (about 20 seconds at a time), stirring between intervals until smooth and gooey. Alternatively, use store-bought marshmallow fluff for convenience.
Set aside to cool slightly but remain spreadable.

Step 3: Make the Chocolate Topping

In a small saucepan over low heat, combine the chocolate chips and heavy cream , stirring constantly until melted and smooth. Remove from heat and let it cool slightly.

Step 4: Assemble the Sandwich Cookies

Pair two cooled peanut butter cookies together—one as the top and one as the bottom.
Spread a generous amount of the marshmallow filling onto the flat side of one cookie.
Top with the second cookie to form a sandwich.
Drizzle or dip the assembled sandwiches in the chocolate topping , ensuring they’re evenly coated.

Step 5: Serve and Enjoy!

Place the cookies on a wire rack to allow excess chocolate to drip off, then let the chocolate set at room temperature or in the refrigerator.
Store the cookies in an airtight container at room temperature for up to 3 days—or freeze for longer enjoyment.

Tips for Making Perfect Peanut Butter S’mores Sandwich Cookies

Don’t Overbake the Cookies : Keep them soft and chewy by removing them from the oven while their centers are still slightly underdone—they’ll continue cooking as they cool.
Customize the Filling : Use different types of marshmallows, such as flavored ones, or mix in crushed graham crackers for added crunch.
Go Nut-Free : Swap almond butter or sunflower seed butter for peanut butter to make these cookies nut-free.
Add Extra Texture : Sprinkle crushed graham cracker crumbs over the melted chocolate for an authentic s’mores touch.
Make Ahead : Prepare the cookies and fillings separately, then assemble just before serving for optimal freshness.
