Ingredients You’ll Need

Every ingredient in this recipe is chosen for a reason, and together they create that perfect balance of chewy, crispy, gooey, and chocolatey. Let’s take a quick peek at what makes each element essential for Peanut Butter S’mores Sandwich Cookies.

Unsalted butter (1 cup, softened): The secret to buttery, tender cookies; be sure it’s room temperature for easy mixing.
Creamy peanut butter (1 cup): Adds that unmistakable nutty richness and chewy texture—don’t use the natural kind for best results!
Granulated sugar (1 cup): Helps the cookies spread just right and keeps the crumb delicate.
Packed brown sugar (1 cup): Brings moisture and a hint of caramel flavor for extra depth.
Large eggs (2): Bind everything together for a soft, cohesive dough.
Vanilla extract (2 teaspoons): Enhances all the sweet flavors and rounds out the cookie dough.
All-purpose flour (2 1/2 cups): Provides the structure that holds these sandwich cookies together.
Baking soda (1 teaspoon): Lifts and lightens the texture for a perfect bite.
Baking powder (1/2 teaspoon): Gives a gentle rise, keeping the cookies soft and fluffy.
Salt (1/2 teaspoon): Balances the sweetness and intensifies the peanut butter flavor.
Graham cracker crumbs (1 cup): A nod to the classic s’mores base, adding a subtle crunch and toasty flavor.
Mini marshmallows (1 1/2 cups): For that iconic gooey, stretchy filling—don’t skimp!
Semi-sweet chocolate chips (1 1/2 cups): Melty chocolate is a must, but feel free to swap in your favorite variety.

How to Make Peanut Butter S’mores Sandwich Cookies

Step 1: Prepare Your Oven and Baking Sheets

Preheat your oven to 350°F (175°C) and line two large baking sheets with parchment paper. This ensures your cookies bake evenly and release easily, so you’ll have perfect Peanut Butter S’mores Sandwich Cookies every time.

Step 2: Mix the Creamy Base

In a large bowl, beat together the softened butter, creamy peanut butter, granulated sugar, and brown sugar until the mixture is smooth and fluffy. This step is key—creaming these ingredients well gives your cookies their tender texture and rich flavor.

Step 3: Add the Eggs and Vanilla

Crack in the eggs, one at a time, followed by the vanilla extract. Mix until everything is nicely combined; you’ll notice the dough getting silkier and lighter in color, which means you’re right on track.

Step 4: Combine the Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, baking powder, salt, and graham cracker crumbs. The graham crumbs are what set these cookies apart, lending that signature s’mores flavor and a bit of extra crunch.

Step 5: Make the Dough

Gradually add the dry ingredients to the wet mixture, mixing just until a soft dough forms. Be gentle here—overmixing can make your cookies tough, and we want them delightfully chewy!

Step 6: Shape and Bake the Cookies

Scoop out tablespoon-sized portions of dough, roll them into balls, and space them about 2 inches apart on your prepared baking sheets. Gently flatten each ball with your palm so they bake up the perfect thickness. Bake for 9 to 11 minutes, just until golden at the edges. Let them cool completely—this makes them easier to handle when assembling your Peanut Butter S’mores Sandwich Cookies.

Step 7: Assemble the Sandwiches

Take one cookie and pile a few mini marshmallows on its flat side. Toast the marshmallows under the broiler for a few seconds or use a kitchen torch for a fun, toasty finish. Top with a few chocolate chips, then gently press another cookie on top to sandwich everything together. The heat will melt the chocolate and marshmallows into a gooey, irresistible filling!

How to Serve Peanut Butter S’mores Sandwich Cookies

Garnishes

For a little extra flair, try drizzling the tops with melted chocolate or dusting with a sprinkle of crushed graham crackers. If you’re feeling fancy, a pinch of flaky sea salt brings out the best in the peanut butter and chocolate combo.

Side Dishes

These cookies are rich and satisfying on their own, but they pair beautifully with a tall glass of cold milk or a scoop of vanilla ice cream. For a grown-up twist, serve them with coffee or a mug of hot cocoa for the ultimate cozy treat.

Creative Ways to Present

Stack your Peanut Butter S’mores Sandwich Cookies high on a rustic wooden board for a campfire-inspired dessert spread, or individually wrap them with ribbon for adorable party favors. For a playful touch, set up a “build-your-own” cookie bar with extra marshmallows, chocolate chips, and graham cracker crumbs so everyone can customize their own creation.

Make Ahead and Storage

Storing Leftovers

Once assembled, keep your Peanut Butter S’mores Sandwich Cookies in an airtight container at room temperature for up to three days. They’ll stay soft and gooey, though you may notice the marshmallow filling gets a little sticky (which, honestly, just makes them more fun to eat).

Freezing

If you want to make these in advance, freeze the unfilled cookies in a sealed bag for up to two months. When you’re ready to serve, thaw at room temperature and assemble with fresh marshmallows and chocolate for that just-baked taste.

Reheating

To enjoy that gooey, melty center again, pop a sandwich cookie in the microwave for 10-15 seconds, or warm in a low oven for a few minutes. The marshmallow and chocolate will soften up, making every bite just as dreamy as when they were freshly made.

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! Crunchy peanut butter will add an extra layer of texture and nutty bits to your Peanut Butter S’mores Sandwich Cookies. Just keep in mind that the cookies might not spread quite as evenly, but they’ll still taste amazing.

What’s the best way to toast the marshmallows if I don’t have a kitchen torch?

No torch? No problem! Simply place the cookies with marshmallows under your oven’s broiler for a very quick toast—just keep a close eye so they don’t burn. It only takes a few seconds for that perfect golden finish.

Can I substitute marshmallow fluff for mini marshmallows?

Yes, marshmallow fluff works beautifully for an extra gooey center. Just spread a dollop on the cookie before adding the chocolate chips and sandwiching. It’s a little messier, but totally worth it for marshmallow lovers!

Are there any nut-free options?

If you need a nut-free version, you can try using sunflower seed butter in place of peanut butter. The flavor will be slightly different, but you’ll still get that creamy, satisfying texture in your sandwich cookies.

How can I make these cookies gluten-free?

Swap the all-purpose flour for a gluten-free baking blend and use gluten-free graham crackers for the crumbs. The rest of the ingredients in Peanut Butter S’mores Sandwich Cookies are naturally gluten-free, so you can still enjoy all the gooey goodness without worry.

Final Thoughts

If you’re looking for a nostalgic treat that’s both comforting and a little bit over-the-top, you have to give Peanut Butter S’mores Sandwich Cookies a try. They’re fun to make, even more fun to eat, and guaranteed to spark smiles around the table. Happy baking!

Instructions

Preheat and prepare: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper to prevent sticking and ensure even baking.
Make the wet mixture: In a large bowl, beat together the softened butter, creamy peanut butter, granulated sugar, and brown sugar until the mixture is creamy and smooth, about 2-3 minutes.
Add eggs and vanilla: Incorporate the eggs one at a time along with the vanilla extract; mix until thoroughly combined and homogenous.
Combine dry ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, salt, and graham cracker crumbs to ensure even distribution.
Mix dry into wet: Gradually add the dry ingredients to the wet mixture, stirring until a cohesive dough forms, being careful not to overmix.
Shape cookies: Scoop tablespoon-sized portions of dough, roll them into balls, and place onto the prepared baking sheets about 2 inches apart. Flatten each ball slightly with the palm of your hand to create cookie shapes.
Bake cookies: Bake in the preheated oven for 9 to 11 minutes, or until the edges turn golden brown, then remove and allow cookies to cool completely on pans or wire racks.
Assemble s’mores sandwiches: On the flat side of one cooled cookie, place a few mini marshmallows. Toast them briefly under the broiler or carefully with a kitchen torch until soft and slightly melted.
Add chocolate chips and sandwich: Top the melted marshmallows with a few semi-sweet chocolate chips, then press gently with another cookie on top to sandwich and help the chocolate and marshmallows meld together.
Serve: Enjoy the sandwich cookies warm for gooey goodness or let them set before storing in an airtight container for up to 3 days.
