🔁 Substitutions & Tips
- Peanut Butter: Natural peanut butter may change the texture—use shelf-stable creamy PB for best results.
- No marshmallow fluff? Use toasted mini marshmallows or homemade marshmallow creme.
- Chocolate swap: Use dark or milk chocolate instead of semi-sweet if you prefer.
👩🍳 Instructions
1. Preheat & Prep
Preheat oven to 350°F (175°C).
Line a baking sheet with parchment paper or a silicone baking mat.
2. Make the Dough
In a mixing bowl, combine:
- Peanut butter
- Granulated sugar
- Brown sugar
- Egg
- Vanilla extract
- Baking soda
- Salt
Mix until smooth and cohesive.
3. Shape & Bake
Scoop tablespoon-sized portions of dough and roll into balls.
Place on the baking sheet, spacing them 2 inches apart.
Use a fork to flatten each ball in a crisscross pattern.
Bake for 8–10 minutes, or until edges are golden.
Cool on sheet for 5 minutes, then transfer to a wire rack.
4. Assemble the Sandwiches
Spread melted chocolate on the flat side of one cookie.
Top with a dollop of marshmallow fluff.
Place another cookie on top and gently press to sandwich.
Repeat with remaining cookies.
5. Set & Serve
Let cookies sit for 10 minutes to allow chocolate to set.
Optional: Use a kitchen torch to lightly toast the marshmallow fluff for that authentic s’mores vibe.
💡 Tips for Success
- Use room-temperature ingredients for smooth dough.
- Chill dough for 15 minutes before baking for thicker cookies.
- To avoid a sticky mess, lightly oil your spoon when scooping fluff.
