For the Peanut Butter Cookies:

  • 1 cup (2 sticks, 230g) unsalted butter, softened
  • ¾ cup (180g) creamy peanut butter
  • ¾ cup (150g) granulated sugar
  • ¾ cup (150g) packed brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 2 cups (240g) all-purpose flour
  • ½ teaspoon baking soda
  • ¼ teaspoon salt

For the Marshmallow Filling:

  • 3 cups mini marshmallows
  • 2 tablespoons creamy peanut butter
  • 1 teaspoon vanilla extract

Optional Coating / Decoration:

  • ½ cup finely crushed graham crackers
  • ¼ cup melted chocolate (for drizzling)

🍪 Instructions

1. Prepare the Cookie Dough

  1. In a large mixing bowl, beat softened butter, peanut butter, granulated sugar, and brown sugar until light and fluffy.
  2. Add the egg and vanilla extract, mixing until fully incorporated.
  3. In a separate bowl, whisk together flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, blending until a soft dough forms.
  4. Cover and chill the dough for 30 minutes.

2. Shape and Bake the Cookies

  1. Preheat oven to 350°F (175°C).
  2. Roll chilled dough into 1-inch balls and place on a parchment-lined baking sheet. Flatten each slightly with the back of a spoon or fork.
  3. Bake 10–12 minutes, or until edges are lightly golden.
  4. Allow cookies to cool completely on a wire rack before assembling.

3. Make the Marshmallow Filling

  • In a medium bowl, combine mini marshmallows, peanut butter, and vanilla. Stir until marshmallows are evenly coated and mixture holds together.

4. Assemble the Sandwich Cookies

  1. Take one cookie and spread or dollop a generous amount of the marshmallow mixture onto the flat side.
  2. Top with another cookie to create a sandwich.

5. Optional Dipping or Drizzling

  • Roll sides in crushed graham crackers or drizzle melted chocolate over the top for an extra-special touch.

🏛 History & Formation

S’mores originated in early 20th-century America as a popular treat for campers, combining graham crackers, chocolate, and roasted marshmallows. The combination of peanut butter cookies and marshmallow filling is a modern twist, inspired by the nutty flavors of peanut butter cups and the gooey charm of classic s’mores. Transforming this campfire favorite into a cookie sandwich allows for a portable, indulgent dessert that retains the nostalgic flavors of a traditional s’more.


💡 Tips & Methods

  • For perfectly soft cookies: Do not overbake; the centers should remain slightly soft.
  • Marshmallow filling tip: If mixture seems loose, briefly microwave 10–15 seconds to help the marshmallows bind.
  • Storage: Keep assembled cookies in an airtight container at room temperature for 2–3 days or refrigerate for up to a week.
