Ingredients You’ll Need

What makes these cookies sing is a lineup of familiar, unfussy ingredients. Each element—from the buttery cookie base to the crunchy graham edge—plays an essential role in achieving that magical s’mores-meets-peanut-butter flavor and texture. Here’s what you’ll need and why each item matters:

Unsalted butter (1/2 cup, softened): Provides richness and creates that irresistibly tender cookie texture.
Creamy peanut butter (1/2 cup): Delivers classic peanutty flavor; choose creamy for smooth, meltaway cookies.
Granulated sugar (1/2 cup): Adds sweetness and helps the cookies spread to just the right thickness.
Packed light brown sugar (1/2 cup): Infuses extra moisture, chewiness, and depth thanks to a touch of molasses.
Large egg (1): Binds everything together and brings structure.
Vanilla extract (1 teaspoon): Rounds out all the flavors for a bakery-quality finish.
All-purpose flour (1 1/4 cups): Forms the sturdy backbone of the cookie, perfect for sandwiching that oozy middle.
Baking soda (1/2 teaspoon): Ensures the right lift and airy texture.
Baking powder (1/2 teaspoon): Helps achieve just a hint of puff for that ideal thickness.
Salt (1/4 teaspoon): Balances the sweetness and highlights the peanut butter and chocolate.
Mini marshmallows (1 cup): For that classic s’mores goo and chewiness in every bite.
Milk chocolate (4 ounces, broken into squares): Melts beautifully for the signature s’mores pocket.
Graham cracker crumbs (1 cup): The finishing touch for the true campfire cookie effect.

How to Make Peanut Butter S’mores Sandwich Cookies

Step 1: Prepare and Preheat

Begin by preheating your oven to 350°F (175°C) and lining your baking sheets with parchment paper. This simple step ensures the cookies bake evenly and easily lift off without sticking or mess—set the perfect backdrop for sandwiching gooey fillings later.

Step 2: Cream Your Cookie Base

In a large bowl, beat together the softened butter, creamy peanut butter, granulated sugar, and packed light brown sugar until the mixture is wonderfully creamy and pale. This creaming step is key for that tender, melt-in-your-mouth texture Peanut Butter S’mores Sandwich Cookies are known for.

Step 3: Add Eggs and Vanilla

Mix in the egg and vanilla extract, blending just until smooth. These give the dough extra richness and an aromatic hint of vanilla, seamlessly tying together all those classic cookie flavors.

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Gradually mix the dry ingredients into your wet mixture until everything is just incorporated—take care not to overmix so your cookies stay soft and tender.

Step 5: Portion and Fill

Scoop out dough and roll it into 1-inch balls. Flatten each ball slightly with your hands. For half the cookies, gently place a piece of milk chocolate and a few mini marshmallows in the center. If you want extra gooeyness, sneak in a dab of peanut butter too.

Step 6: Assemble the Sandwiches

Top each filled cookie base with a second cookie, making a sandwich. Gently press and seal the edges so that the irresistible filling stays nestled inside. This is where the sandwich magic happens!

Step 7: Roll and Bake

Lightly roll the edges of each assembled cookie in graham cracker crumbs to coat. Arrange them about 2 inches apart on your prepared baking sheets. Bake for 10–12 minutes, or until the edges look golden and the marshmallows inside are beginning to melt.

Step 8: Cool and Enjoy

Allow your Peanut Butter S’mores Sandwich Cookies to cool on the baking sheet for 5 minutes before gently transferring them to a wire rack. This moment lets the gooey centers set just enough without making a mess, so every bite is pure s’mores joy.

How to Serve Peanut Butter S’mores Sandwich Cookies

Garnishes

Sprinkle a little extra graham cracker crumble or chopped chocolate over the top of each sandwich cookie for dramatic flair. A dusting of powdered sugar or even a small drizzle of melted chocolate takes them firmly into bakery territory.

Side Dishes

While these Peanut Butter S’mores Sandwich Cookies are stars all on their own, they pair wonderfully with cold milk, a frothy hot chocolate, or even an iced coffee. For a full dessert platter, add fresh berries or a scoop of vanilla ice cream alongside.

Creative Ways to Present

Stack them high on a vintage cake stand, package in clear bags tied with ribbon for the cutest edible gift, or layer in a rustic basket for a picnic dessert. For parties, consider arranging them in a circle on a wood board, with extra marshmallows and chocolate pieces scattered for playful, campfire-inspired presentation.

Make Ahead and Storage

Storing Leftovers

Store any leftover Peanut Butter S’mores Sandwich Cookies in an airtight container at room temperature; they’ll keep their soft, chewy texture for up to three days. If you like a slightly crisp edge, pop the lid open for a short time before serving.

Freezing

Want to prep ahead? Freeze the fully assembled but unbaked cookies on a baking sheet until solid, then transfer to a freezer-friendly bag. Bake directly from frozen, just adding a couple extra minutes to the bake time. Baked cookies also freeze well—just thaw at room temperature before digging in.

Reheating

If you love your Peanut Butter S’mores Sandwich Cookies extra gooey, microwave them for 8 to 10 seconds before serving. The marshmallow and chocolate will melt just enough for a dreamy, straight-from-the-campfire effect.

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! Crunchy peanut butter will give the cookies extra texture and little flecks of roasted peanut throughout. It’s a fun twist if you want more crunch in each bite.

Can I make these cookies gluten-free?

Yes! Swap in your favorite gluten-free all-purpose flour and gluten-free graham crackers. Just double-check the texture of the dough and adjust with a splash more of flour if needed, since gluten-free blends vary.

How do I keep the marshmallows from melting out?

Be sure to seal the cookie edges well and don’t overfill. Using mini marshmallows helps too, as they nestle in the dough better and melt more consistently.

What’s the best way to make the centers extra gooey?

For ultimate goo factor, add a tiny dollop of peanut butter with the chocolate and marshmallows before sealing the cookie. Baking just until the edges are golden but the centers are soft will also help!

Can I use dark chocolate instead of milk chocolate?

Definitely! Dark chocolate adds a deeper, more intense chocolate flavor that balances the sweetness of the marshmallow and peanut butter perfectly.

Final Thoughts

If you’re feeling the urge to treat yourself and your favorite people, don’t wait—make a batch of Peanut Butter S’mores Sandwich Cookies. They’re every bit as delightful as they sound, and I guarantee they’ll add a spark of joy (and lots of smiles) to your snack table. Happy baking!
