Ingredients Needed
For the cookies:

- 1/2 cup granulated sugar
- 1/2 cup packed light brown sugar

- 1 teaspoon pure vanilla extract
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
For the filling:
- 1 cup semi-sweet chocolate chips, melted
- 1 cup marshmallow fluff
How to Make Peanut Butter S’mores Sandwich Cookies
- Preheat the Oven: Start by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking.
- Mix the Cookie Dough: In a large mixing bowl, combine 1 cup of creamy peanut butter, 1/2 cup of granulated sugar, 1/2 cup of packed light brown sugar, 1 large egg, 1 teaspoon of vanilla extract, 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt. Mix everything together until the dough is smooth and fully combined.
- Shape the Cookies: Scoop out tablespoon-sized portions of the dough and roll them into balls. Place these balls on the prepared baking sheet, making sure to leave about 2 inches between each one.
- Flatten the Dough: Use a fork to gently flatten each ball, creating a crisscross pattern on top. This not only looks nice but helps the cookies bake evenly.
- Bake: Place the baking sheet in the oven and bake for 8-10 minutes, or until the edges are lightly golden. Once done, let the cookies cool on the sheet for 5 minutes before transferring them to a wire rack to cool completely.
- Prepare the Filling: While the cookies cool, melt 1 cup of semi-sweet chocolate chips in a microwave-safe bowl or using a double boiler. Stir until the chocolate is smooth.
- Assemble the Cookies: To make the sandwiches, spread a thin layer of melted chocolate on the bottom of one cookie. Add a dollop of marshmallow fluff on top of the chocolate, then place another cookie on top, gently pressing down to form a sandwich. Repeat this step with the remaining cookies.
- Let Set: Allow the assembled cookies to sit for about 10 minutes for the chocolate to set slightly. For a fun twist, use a kitchen torch to lightly toast the marshmallow fluff peeking out from the sides.
- Enjoy: Serve immediately or store in an airtight container at room temperature for up to 3 days.
Serving and Storage Tips
To enhance presentation, place the cookies on a decorative plate or cookie stand. They are best enjoyed fresh but can be stored easily. Keep them in an airtight container at room temperature for up to 3 days to maintain their flavor and texture.
Helpful Notes
- Tips for Success: Ensure that your peanut butter is well mixed for the best texture. If you prefer softer cookies, bake them a minute less.
- Variations: You can try using different types of chocolate (like milk or dark chocolate) and even swap out the marshmallow fluff for chocolate ganache for a twist!
