- 1 large egg

🔪 Equipment Needed
- Mixing bowls
- Hand mixer or stand mixer
- Measuring tools
- Baking sheets
- Parchment paper or silicone baking mat
- Spatula
- Spoon or cookie scoop
👩🍳 Step-by-Step Instructions
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C) . Line baking sheets with parchment paper or a silicone baking mat.
Step 2: Cream Butter and Sugars
In a large mixing bowl:
- Beat softened butter , granulated sugar , and brown sugar together using a hand mixer until light and fluffy — about 2–3 minutes .
Step 3: Add Wet Ingredients
Mix in peanut butter , followed by the egg and vanilla extract . Blend well until smooth and fully combined.
Step 4: Mix Dry Ingredients
In a separate bowl:
- Whisk together:
- 2½ cups flour
- ½ tsp baking soda
- ¼ tsp salt
Gradually add dry ingredients to the wet mixture and mix until just combined.
Step 5: Shape the Cookies
Using a spoon or cookie scoop:
- Drop rounded portions of dough onto the prepared baking sheet, spacing them about 2 inches apart .
- Flatten each cookie slightly with the back of a fork in a crisscross pattern if desired.
Step 6: Bake Until Golden
Bake for 10–12 minutes , or until the edges are lightly golden and the centers are set.
Let cool completely before assembling the sandwiches.
Step 7: Prepare the S’mores Filling
While the cookies cool:
- Spread marshmallow fluff or place a few mini marshmallows on the bottom side of half the cookies.
- Press gently to flatten the marshmallow layer.
- Top the other half with chocolate chips or chunks — they’ll melt slightly when pressed together.
Tip: For an extra gooey center, briefly toast the marshmallows with a kitchen torch before sandwiching.
Step 8: Assemble the Sandwiches
Pair up cookie halves and gently press them together to form a sandwich.
For extra flair, spread a thin layer of melted chocolate or crushed graham crackers between the layers.
Step 9: Serve & Enjoy!
Store the cookies in an airtight container and let them sit for 1–2 hours before eating — this allows the flavors to meld and the filling to soften beautifully.
Serve with a cold glass of milk or your favorite coffee for the ultimate combo!
