Ingredients
For the Peanut Butter Cookies:
- 1 cup creamy peanut butter
- ½ cup granulated sugar
- ½ cup brown sugar
- 1 large egg
- 1 teaspoon vanilla extract
- ½ teaspoon baking soda
- ¼ teaspoon salt
For the Filling:
- 1 cup chocolate chips, melted (dark, semi-sweet, or milk)
- 1 cup marshmallow fluff
Tools You’ll Need
- Mixing bowl
- Electric mixer or sturdy spoon
- Baking sheet
- Parchment paper
- Spatula or butter knife for spreading
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup.
Step 2: Make the Cookie Dough
In a mixing bowl, combine peanut butter, granulated sugar, brown sugar, egg, vanilla, baking soda, and salt. Stir or beat until smooth and fully combined.
Step 3: Shape the Cookies
Roll the dough into small balls (about 1 tablespoon each) and place them on the prepared baking sheet.
Flatten each ball with a fork to create the signature crisscross pattern.
Step 4: Bake
Bake for 8–10 minutes, or until the edges are set and the tops look slightly cracked.
Let the cookies cool completely on the pan before handling — they’ll firm up as they cool.
Step 5: Assemble the Sandwiches
Once cooled, spread a layer of melted chocolate on the bottom of one cookie.
Add a spoonful of marshmallow fluff on top of the chocolate, then gently sandwich with another cookie.
Step 6: Set and Enjoy
Let the sandwiches rest for about 10 minutes (or refrigerate briefly) so the chocolate firms up. Then bite in and enjoy that perfect s’mores-meets-cookie goodness!
Tips for Perfect Sandwich Cookies
- Cool completely: Warm cookies will melt the chocolate and fluff.
- Extra toasty flavor: Lightly torch or broil the marshmallow fluff for a true s’mores vibe! 🔥
- Make ahead: You can bake the cookies a day ahead and assemble before serving.
- Mix it up: Try using Nutella instead of melted chocolate, or add crushed graham crackers to the marshmallow layer for extra texture!

Frequently Asked Questions
Q: Can I use natural peanut butter?

Q: Can I use mini marshmallows instead of fluff?
A: Absolutely! Toast them slightly under the broiler before sandwiching for that classic s’mores flavor.

A: Definitely — it adds a lovely texture and a bit of extra crunch.
