Ingredients You’ll Need

Gathering these ingredients is a breeze, and each one plays a crucial role in making these cookies the perfect blend of texture and flavor. From the nutty richness of peanut butter to the light sweetness of marshmallows, every bite is balanced beautifully.

• 1 cup all-purpose flour: The sturdy base that gives our cookies structure and a tender crumb.
• 1/2 cup granulated sugar: Adds sweetness and helps achieve a slight crisp around the cookie edges.
• 1/2 cup brown sugar: Brings moisture and a warm, caramel-like depth to the cookie dough.
• 1/2 cup unsalted butter, softened: Contributes to a rich flavor and soft texture.
• 1/2 cup creamy peanut butter: The star ingredient that delivers that unmistakable peanut butter flavor and creamy consistency.
• 1 large egg, room temperature: Binds everything together for a smooth dough.
• 1 tsp vanilla extract: Enhances the overall flavor with sweet aromatic notes.
• 1/2 tsp baking soda: Helps the cookies rise just enough for a tender, soft bite.
• 3/4 cup semi-sweet chocolate chips: For gorgeous pockets of melty chocolate throughout.
• 1 cup mini marshmallows: The gooey, fluffy filling that makes these cookies a true s’mores delight.

How to Make Peanut Butter S’mores Sandwich Cookies Recipe

Step 1: Preheat and Prepare

First things first, crank your oven up to 350°F (175°C). This ensures your cookies have the perfect environment to rise and bake evenly. Line baking sheets with parchment paper or silicone mats to prevent sticking—this prep step will save you time and effort later on.

Step 2: Cream the Butter, Sugars, and Peanut Butter

In a large mixing bowl, beat together the softened butter, granulated sugar, brown sugar, and creamy peanut butter until the mixture looks light and fluffy. This step is key because it aerates the dough, which helps give your cookies a tender crumb and rich flavor that’s simply dreamy.

Step 3: Add Egg and Vanilla

Next, crack in the egg and pour in the vanilla extract. Beat these ingredients together until fully combined, making sure your dough is smooth. The egg acts as a binder, while the vanilla lifts the flavor, making every bite more enticing.

Step 4: Mix Dry Ingredients and Combine

In a separate bowl, whisk together the all-purpose flour and baking soda. Gradually add this dry mix into your wet ingredients, stirring just until you no longer see streaks of flour. Avoid overmixing here to keep your cookies tender rather than tough.

Step 5: Fold in Chocolate Chips

Now for the chocolate magic: gently fold in the semi-sweet chocolate chips. These little gems will melt during baking into luscious pockets of chocolate that balance perfectly with the peanut butter base.

Step 6: Scoop Dough onto Baking Sheets

Use a tablespoon or cookie scoop to drop uniform dollops of dough onto your prepared baking sheets. Be sure to space them nicely apart because they will spread slightly while baking. This helps them bake evenly and gives you beautifully shaped cookies.

Step 7: Bake Until Edges Are Golden

Bake for 10 to 12 minutes, watching for soft centers and golden edges. This timing ensures your cookies are cooked through but still tender and chewy inside—the hallmark of exceptional peanut butter cookies.

Step 8: Add Mini Marshmallows and Finish Baking

Once out of the oven, press several mini marshmallows firmly into the center of each cookie. Pop them back in the oven for an additional 1 to 2 minutes to let the marshmallows puff up and become delightfully gooey. This step really takes the s’mores vibe to the next level.

Step 9: Cool Slightly and Sandwich

Allow the cookies to cool for a few minutes until they are firm enough to handle but still warm. Then, sandwich two cookies together with the melted marshmallows nestled in the middle. This is when the magic truly happens; each bite is a nostalgic, melty treat you’ll want to savor.

Make Ahead and Storage

Storing Leftovers

Store leftover Peanut Butter S’mores Sandwich Cookies Recipe treats in an airtight container at room temperature for up to 3 days. This keeps them soft and fresh, allowing the marshmallows to remain wonderfully gooey.

Freezing

You can freeze these cookies by placing the sandwiches in a single layer on a baking sheet to freeze solid, then transferring them to a freezer-safe bag. They keep wonderfully for up to 2 months. Just thaw at room temperature when you’re ready to indulge.

Reheating

Warm the cookies gently in the microwave for 10-15 seconds to revive that melty marshmallow and soften the peanut butter for a truly irresistible experience. Be careful not to overheat, or the marshmallows might get too tough.

FAQs

Can I use chunky peanut butter instead of creamy?

Absolutely! Chunky peanut butter will add a delightful crunch to your cookies, giving them a bit more texture. Just expect a slightly different mouthfeel but the flavor will still shine wonderfully.

Are these cookies gluten-free?

Since the recipe calls for all-purpose flour, these cookies are not gluten-free as written. However, you can substitute with a gluten-free all-purpose baking flour blend to make them suitable for gluten-sensitive diets. Just check that your other ingredients are gluten-free.

Can I substitute the chocolate chips for another type of chocolate?

Definitely! Feel free to use white chocolate chips, milk chocolate chunks, or even chopped dark chocolate bars. Each option will add its own twist to the flavor profile while keeping the spirit of the Peanut Butter S’mores Sandwich Cookies Recipe intact.

What can I use instead of mini marshmallows?

If mini marshmallows aren’t available, small pieces of regular marshmallows work just as well. Just chop them into smaller bits for even distribution, or try marshmallow fluff spread between the cookies for an ooey-gooey alternative.

How do I prevent the marshmallows from burning?

To avoid burning, add the marshmallows only during the last 1 to 2 minutes of baking and keep a close eye on them. They should puff up nicely without turning too brown. If your oven tends to run hot, reduce the time slightly.
