Preparation Phase & Tools to Use (Essential Tools and Equipment, and the Importance of Each Tool)

Creating Peanut Butter S’mores Sandwich Cookies is delightfully simple, but having the right tools makes all the difference for texture, consistency, and ease.

Essential Tools:

• Mixing Bowls
  For combining your cookie dough and fillings. Use a large one for the dough and smaller ones for your marshmallow fluff and melted chocolate.
• Hand Mixer or Stand Mixer
  Crucial for achieving a smooth, creamy cookie dough. A mixer ensures your peanut butter, sugar, and egg are well blended for the perfect cookie base.
• Baking Sheet
  A sturdy, non-stick baking sheet is essential for evenly baked cookies with golden-brown edges.
• Parchment Paper or Silicone Baking Mat
  Keeps the cookies from sticking and makes cleanup a breeze.
• Cookie Scoop or Tablespoon
  Helps create uniform cookie sizes, ensuring even baking and ideal sandwiching.
• Cooling Rack
  Allows cookies to cool evenly and prevents them from becoming soggy underneath.
• Spatula or Butter Knife
  For spreading marshmallow fluff and chocolate onto the cookies cleanly and evenly.

Preparation Tips

• Soften the Peanut Butter Slightly
  If your peanut butter is thick, microwave it for a few seconds. This helps it blend more easily into the dough.
• Chill the Dough (Optional but Recommended)
  If your dough feels sticky or soft, chilling it for 20–30 minutes helps control spreading and yields a thicker cookie.
• Bake Evenly
  Rotate the baking sheet halfway through baking to ensure all cookies are uniformly golden.
• Use Room Temperature Ingredients
  Especially the egg—this helps it incorporate better into the dough, creating a smooth and cohesive mix.
• Don’t Overbake
  Peanut butter cookies can become dry if overdone. Remove them just as the edges set and the centers look slightly soft—they’ll firm up as they cool.

Step-by-Step Instructions for Peanut Butter S’mores Sandwich Cookies

Let’s bring these irresistible sandwich cookies to life, step by delicious step.

---

Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C).
Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking and promote even baking.

---

Step 2: Make the Cookie Dough

In a large bowl, combine the peanut butter, sugar, egg, and vanilla extract.
Mix with a hand mixer or stand mixer on medium speed until the dough is smooth and well incorporated. The dough will be thick and slightly sticky.

---

Step 3: Shape the Cookies

Using a cookie scoop or tablespoon, form small dough balls and place them on the prepared baking sheet about 2 inches apart.
Flatten each ball gently with a fork in a criss-cross pattern (a signature peanut butter cookie look).

---

Step 4: Bake

Bake for 8–10 minutes, or until the edges are just starting to turn golden.
The centers should look slightly soft—that’s how you keep them chewy.
Let them cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

---

Step 5: Prepare the Filling

While the cookies are cooling, prepare the filling.

• Warm your chocolate spread slightly (10–15 seconds in the microwave) for easy spreading.
• Have your marshmallow fluff at room temperature for better texture.

---

Step 6: Assemble the Sandwiches

Once the cookies are completely cool, flip half of them upside down.

• Spread a layer of chocolate spread on the flat side.
• Then add a dollop of marshmallow fluff on top.
• Gently press another cookie on top to form a sandwich.

Tip: Don’t press too hard—just enough to get that nice gooey squish.

---

Step 7: Set and Serve

Allow the assembled cookies to sit for 10–15 minutes to let the filling settle (or refrigerate briefly to firm them up).
Serve and enjoy the ultimate treat!

---

Notes

• Customizable Fillings: While marshmallow fluff and chocolate are the classic s’mores combo, feel free to play with flavors—try hazelnut spread, white chocolate, or even a bit of raspberry jam for a fruity twist.
• Gluten-Free Friendly: These cookies naturally contain no flour, making them gluten-free. Just double-check the labels on your spreads to ensure they’re compliant.
• Double Batch It: These go fast! Consider doubling the recipe if you’re making them for a party or holiday tray.
• Make-Ahead Tip: You can bake the cookies a day in advance and assemble the sandwiches just before serving for peak freshness and texture.
• Warm Them Up: A quick 5–10 seconds in the microwave makes them gooey and melty like a true s’more.

Watch Out for These Mistakes While Cooking

1. Overbaking the Cookies

Peanut butter cookies firm up after cooling, so removing them from the oven too late leads to a dry, crumbly texture. Pull them once the edges are just golden.

2. Using Natural Peanut Butter

Natural peanut butter separates and creates an oily dough that doesn’t hold shape well. Stick to conventional creamy peanut butter for best results.

3. Skipping the Cooling Time

Warm cookies will fall apart during assembly. Be patient and let them cool completely before adding the filling.

4. Overfilling the Sandwiches

Too much marshmallow or chocolate can lead to oozing out the sides. Use a moderate amount and gently press the top cookie.

5. Using Hot Filling

Ensure the chocolate spread is only slightly warmed—not hot—so it doesn’t melt the cookie or cause the fluff to collapse.

These rich, gooey treats are delicious on their own—but pairing them with the right beverage or side can turn them into a full dessert experience. Whether you’re hosting or simply indulging at home, these ideas elevate the moment.

8 Recommendations

1. Cold Milk (Classic Choice)
   You can’t go wrong with a cold glass of milk—dairy or plant-based. It balances the richness and adds that nostalgic comfort.

   Use these cookies as a base for ice cream sandwiches or serve them alongside a scoop of vanilla or chocolate chip ice cream.
5. Fruit Platter
   Strawberries, bananas, or apple slices provide a refreshing, juicy contrast to the dense sweetness of the cookies.
6. Milkshakes
   Blend up a chocolate, peanut butter, or banana milkshake and pair it with a cookie or two for a retro-style dessert.
7. Cheese Board with Dark Chocolate
   For something more refined, include the cookies in a dessert cheese board featuring nuts, chocolate, and soft cheeses like brie.
8. Whipped Cream Dips
   Serve the cookies with a small bowl of whipped cream or cream cheese frosting for dunking—especially fun for parties!

Frequently Asked Questions

1. Can I use crunchy peanut butter instead of creamy?

Yes! Crunchy peanut butter adds texture and a bit of extra crunch. Just make sure it’s not a natural or oily kind, as that can affect the dough consistency.

---

2. How do I keep the marshmallow fluff from oozing out?

Use a moderate amount of fluff and don’t overpress the cookies when sandwiching. Chilling the assembled cookies briefly also helps the filling stay in place.

---

3. Can I toast the marshmallow for a true s’mores flavor?

Absolutely! A small kitchen torch or quick broil can toast the marshmallow fluff before sandwiching. Just be careful not to overheat the cookie itself.

---

4. What if I don’t have parchment paper?

Grease your baking sheet lightly with butter or non-stick spray. Parchment just makes cleanup easier and helps prevent over-browning on the bottom.

---

5. Are these cookies safe for someone with gluten sensitivity?

Yes! This recipe is naturally gluten-free—just ensure that all other ingredients, like your spreads, are certified gluten-free.

---

6. Can I use regular marshmallows instead of fluff?

Not recommended for sandwiching—they don’t spread as well. However, if you melt them down slightly or toast and press them, they can work in a pinch.

---

7. How far in advance can I make these?

You can bake the cookies 2–3 days in advance. For the best texture, assemble the sandwiches the same day you plan to serve them.

---

8. Can kids help with this recipe?

Yes! Kids love helping shape the cookies and spreading the fillings. Just supervise the oven and any hot tools if toasting the marshmallow.
