Peanut Butter S’mores Sandwich Cookies

These indulgent Peanut Butter S’mores Sandwich Cookies combine soft peanut butter cookies with gooey marshmallow creme and rich melted chocolate for the ultimate treat.

  • Total Time: 1 hour
  • Yield: 12 sandwich cookies 1x

Ingredients

Scale
  • For the Peanut Butter Cookies:
  • 1 cup (2 sticks) unsalted butter, softened
  • ¾ cup creamy peanut butter
  • ¾ cup granulated sugar
  • ¾ cup packed brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 2 ¼ cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • For the Filling:
  • 1 ½ cups marshmallow creme (fluff)
  • 1 cup chocolate chips, melted
  • Optional: crushed graham crackers for extra crunch

Instructions

  1. Make the Dough: In a large bowl, cream together the butter, peanut butter, granulated sugar, and brown sugar until light and fluffy (about 2–3 minutes). Beat in the egg and vanilla until smooth.
  2. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, baking powder, and salt. Gradually mix the dry ingredients into the wet ingredients until a soft dough forms. Do not overmix.
  3. Chill: Cover the dough and refrigerate for at least 30 minutes.
  4. Preheat & Prep: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.
  5. Shape & Bake: Scoop tablespoon-sized portions of dough and roll into balls. Place 2 inches apart. Flatten gently with a fork to create a crisscross pattern. Bake for 9–11 minutes until edges are golden.
  6. Cool: Let cookies cool on the sheet for 5 minutes, then transfer to a wire rack.
  7. Assemble the Sandwiches: Spread marshmallow creme on the bottom of one cookie. Spread melted chocolate on another and sandwich them together. Optional: roll edges in crushed graham crackers.
  8. Serve or Store: Serve immediately or let sit 10–15 minutes for chocolate to set. Store in an airtight container for up to 3 days.

Notes

  • Chilling the dough prevents excessive spreading.
  • Microwave chocolate chips in short bursts for smooth melting.
  • These cookies freeze well—just wrap individually and store in a freezer bag.
