Ingredients Notes

• Creamy Peanut Butter: I always look for smooth, glossy peanut butter with a rich aroma. Its velvety texture creates tender cookies while providing that nostalgic nutty flavor that pairs perfectly with chocolate.
• Unsalted Butter: I choose butter with a pale yellow hue and sweet cream scent. When softened, it incorporates air into the dough, creating cookies with crisp edges and chewy centers.
• Light Brown Sugar: I love its subtle molasses aroma and slightly moist texture. It adds a caramel-like depth and helps maintain moisture in the cookies, ensuring they stay chewy longer.
• Vanilla Extract: I seek out vanilla with a complex, floral fragrance. Just a teaspoon transforms the cookies, adding warmth and sweetness that enhances both the peanut butter and chocolate.
• Marshmallow Fluff: I adore its pillowy, cloud-like appearance and sticky-sweet texture. It provides that authentic s’mores experience without the campfire, staying soft and gooey between cookies.
• Milk Chocolate Chips: I select chips with a glossy sheen and smooth melt. Their creamy sweetness balances the salty peanut butter, creating that classic s’mores flavor we all crave.

How to Make Peanut Butter S’mores Sandwich Cookies

1. Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper. I like to get this done first so everything’s ready when my dough is mixed.
2. In a large bowl, cream together 1½ cups peanut butter, ½ cup softened butter, ½ cup granulated sugar, and ½ cup packed light brown sugar until light and fluffy, about 2-3 minutes. The mixture should lighten in color and look somewhat whipped.
3. Add 1 egg and 1 teaspoon vanilla extract to the butter mixture and beat until well combined. Make sure to scrape down the sides of the bowl to incorporate everything evenly.
4. In a separate bowl, whisk together 1¼ cups all-purpose flour, ¾ teaspoon baking powder, and ¼ teaspoon kosher salt.
5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. The dough will be thick and slightly sticky.
6. Roll the dough into 1½-inch balls (about 2 tablespoons each) and place them 2 inches apart on the prepared baking sheets. I usually get about 24-28 cookies total.
7. Using a fork, gently press a crisscross pattern into each cookie to flatten slightly. This gives them that classic peanut butter cookie look!
8. Bake for 10-12 minutes until the edges are set and just beginning to turn golden brown. The centers might look slightly underdone, but that’s perfect for a chewy texture.
9. Allow the cookies to cool on the baking sheets for 5 minutes before transferring to a wire rack to cool completely. They’ll firm up as they cool.
10. While the cookies cool, microwave ¼ cup peanut butter in 15-second intervals until it’s warm and easily drizzled. Set aside.
11. Pair up your cookies by similar size to make even sandwiches. I like to turn half of them upside down so they’re ready for filling.
12. Spread about 1 tablespoon of marshmallow fluff onto the flat side of one cookie from each pair. Don’t spread it all the way to the edge as it will squish out when sandwiched.
13. Sprinkle about 1 teaspoon of chocolate chips over the marshmallow fluff, pressing them in slightly so they stick.
14. Drizzle a little of the warmed peanut butter over the chocolate chips. I use a small spoon and make a zigzag pattern.
15. Place the second cookie on top, flat side down, and gently press to create a sandwich. The filling should spread to the edges but not ooze out.
16. For the ultimate s’mores experience, you can heat these sandwiches in the microwave for 10 seconds to make the filling gooey and the chocolate slightly melty. Enjoy while still warm!

Expert Tips for Peanut Butter S’mores Sandwich Cookies

• Chill for Perfect Cookies: I always chill my peanut butter cookie dough for 30 minutes before baking. This prevents excessive spreading and creates the ideal texture for sandwich cookies – sturdy enough to hold fillings while staying deliciously chewy.
• Tame That Sticky Fluff: Spray your measuring cup and spoon with non-stick cooking spray before measuring marshmallow fluff. This little trick makes the sticky substance slide right out without frustrating you or wasting any of that gooey goodness.
• Control Your Chocolate Melt: For a more polished look, I use mini chocolate chips or roughly chop regular ones. This ensures even distribution and controlled melting when warmed, preventing chocolate from escaping the sides of your sandwich.
• Assembly Timing Matters: For the very best texture, assemble these sandwich cookies no more than 2 hours before serving. The cookies will stay crisp and the filling perfectly gooey during this window.
• Create a Toasted Effect: For an authentic campfire taste, use a kitchen torch to lightly toast the marshmallow fluff edges before sandwiching. This quick step adds that distinctive toasted marshmallow flavor that makes traditional s’mores so irresistible.

Storage Tips for Peanut Butter S’mores Sandwich Cookies

• Store Components Separately: For make-ahead preparation, keep unfilled cookies in one container and assemble just before serving for the optimal texture.
• Counter-Worthy Timeframe: Plain peanut butter cookies stay fresh in an airtight container at room temperature for up to 5 days. Add a slice of bread to maintain moisture.
• Refrigerate Assembled Cookies: If you need to make them ahead, fully assembled sandwich cookies can be refrigerated for up to 2 days, though they’re best within the first 24 hours.
• Freezer-Friendly Base: Unfilled cookies freeze beautifully for up to 3 months. I place parchment between layers to prevent sticking during the freezing process.
• Quick Revival Method: Microwave refrigerated sandwich cookies for 8-10 seconds to restore that fresh-baked gooey center. The chocolate chips will slightly remelt for maximum enjoyment.
• Airtight Is Essential: Use containers with secure seals for all storage methods. Peanut butter cookies absorb other flavors easily and lose freshness quickly when exposed to air.

Variations and Substitutions for Peanut Butter S’mores Sandwich Cookies

• Almond Butter Swap: Replace peanut butter with almond butter for a milder, more delicate flavor profile that pairs beautifully with the sweet marshmallow filling.
• Gluten-Free Version: Substitute the all-purpose flour with a 1:1 gluten-free flour blend. The cookies will be slightly more tender but maintain their delicious chewy texture.
• Vegan Adaptation: Use plant-based butter, a flax egg (1 Tbsp ground flaxseed + 3 Tbsp water), and vegan marshmallow cream for an equally indulgent plant-based treat.
• Dark Chocolate Upgrade: Swap milk chocolate chips for semi-sweet or dark chocolate chips for a less sweet, more sophisticated flavor that balances the sweet marshmallow beautifully.
• Nutella Twist: Replace the warmed peanut butter drizzle with Nutella for a chocolate-hazelnut dimension that complements both the peanut butter cookies and marshmallow filling.
• Cinnamon Spice Addition: Add 1 teaspoon of ground cinnamon to the cookie dough for a warming spice note that evokes campfire vibes and enhances the s’mores experience.

Perfect Pairings for Peanut Butter S’mores Sandwich Cookies

• Cold Glass of Milk: The cool, creamy milk cuts through the rich peanut butter and sweet marshmallow, while enhancing the chocolate’s depth for a classic cookies-and-milk experience.
• Espresso or Dark Coffee: The bitter complexity of a strong coffee contrasts beautifully with the cookies’ sweetness, while accentuating the chocolate notes and nutty peanut butter flavor.
• Vanilla Bean Ice Cream: Sandwich a scoop between two slightly warm cookies for a decadent dessert that plays with temperature contrasts and creates an elevated ice cream sandwich experience.
• Banana Nice Cream: The fruity freshness balances the rich cookies while complementing both the peanut butter and chocolate flavors—essentially a frozen banana-PB sandwich in dessert form.
• Hot Chocolate with Cinnamon: A spiced hot chocolate doubles down on the s’mores campfire vibe while reinforcing the chocolate notes. Add a cinnamon stick for aromatic warmth.
• Summer Berry Compote: Tart raspberries or strawberries cut through the richness with their bright acidity, creating a PB&J meets s’mores fusion that’s unexpectedly delightful.
