Ingredients

  • 1 cup creamy peanut butter
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup chocolate chips, melted
  • 1 cup marshmallow fluff

Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking and ensure even baking.

Step 2: Make the Peanut Butter Cookie Dough

  1. In a large mixing bowl, combine the creamy peanut butter, granulated sugar, and brown sugar. Mix well until smooth.
  2. Add the egg, vanilla extract, baking soda, and salt. Stir until fully incorporated and a soft dough forms.

Step 3: Shape and Bake the Cookies

  1. Roll the cookie dough into small, even-sized balls, about 1 inch in diameter.
  2. Place the dough balls on the prepared baking sheet, spacing them about 2 inches apart.
  3. Use a fork to gently press down on each cookie, creating a crisscross pattern.
  4. Bake for 8-10 minutes, or until the cookies are golden brown and set.
  5. Remove from the oven and allow the cookies to cool completely on a wire rack before assembling.

Step 4: Prepare the S’mores Filling

  1. Melt the chocolate chips in a microwave-safe bowl in 20-second intervals, stirring after each interval, until smooth and fully melted.
  2. If you want an extra toasted marshmallow flavor, lightly toast the marshmallow fluff using a kitchen torch or by briefly broiling it in the oven.

Step 5: Assemble the Sandwich Cookies

  1. Take one peanut butter cookie and spread a layer of melted chocolate on the bottom.
  2. Add a generous spoonful of marshmallow fluff on top of the chocolate.
  3. Place another cookie on top to create a sandwich, pressing gently to secure it.
  4. Repeat with the remaining cookies.

Step 6: Let Them Set and Serve

Allow the cookies to set at room temperature for about 10 minutes, or place them in the refrigerator for a few minutes to firm up. Once set, they are ready to enjoy.

Tips for the Best Peanut Butter S’mores Sandwich Cookies

  • Let the cookies cool completely before assembling. Warm cookies can cause the chocolate and marshmallow to melt too quickly.
  • For an extra indulgent touch, drizzle additional melted chocolate over the top of each sandwich cookie.
  • Want a crunchier texture? Use crunchy peanut butter instead of creamy for a bit of added crunch.
  • Make them ahead. These cookies store well in an airtight container for up to three days at room temperature.
  • Try different variations. Swap out the peanut butter cookies for classic graham cracker-flavored cookies for a more traditional s’mores taste.
