Essential Ingredients for S’more Peanut Butter Cookies
Crafting these irresistible S’more Peanut Butter Cookies requires a selection of fresh, high-quality ingredients. Here’s what you’ll need to create this perfect blend of nutty, chocolatey, and marshmallowy goodness:
The Best S’more Peanut Butter Cookies Recipe Ingredients:
- Butter (unsalted, softened to room temperature for optimal creaming)
- Creamy peanut butter (ensure it’s a smooth, classic variety, not natural with oil separation)
- Granulated sugar
- Brown sugar (packed, for moisture and chewiness)
- Large egg (at room temperature for better emulsification)
- Vanilla extract (pure vanilla adds the best flavor)
- Salt (fine sea salt works wonderfully to balance sweetness)
- Graham Cracker crumbs (store-bought or finely crushed crackers)
- All-purpose flour (measured correctly, see tips below)
- Baking soda (for lift and tenderness)
- Large marshmallows (use kitchen scissors to cut each marshmallow in half for easy placement)
- Hershey Bar Pieces (classic milk chocolate works best, broken into squares)
Step-by-Step Instructions: How to Make S’mores Peanut Butter Cookies
Get ready to bake the most delightful S’mores Peanut Butter Cookies! Follow these simple instructions for a perfect batch every time:
- First, preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper, or simply use an ungreased baking sheet if parchment isn’t available. This ensures easy removal and consistent baking.

- In a spacious mixing bowl, combine the softened butter, creamy peanut butter, granulated sugar, and packed brown sugar. Using an electric mixer, cream these ingredients together on medium speed until the mixture is light, fluffy, and well combined. This usually takes about 2-3 minutes.
- Once the mixture is creamy, add in the egg, vanilla extract, and salt. Continue to beat with the mixer until all ingredients are fully incorporated and the mixture is smooth. Scrape down the sides of the bowl as needed to ensure everything is evenly mixed.

- Gradually blend in the graham cracker crumbs, flour, and baking soda. Mix on low speed until the dry ingredients are just combined with the wet ingredients. Be careful not to overmix, as this can lead to tough cookies. Stop mixing as soon as no dry streaks of flour remain.
- Using a large cookie scoop (approximately 3 tablespoons) for bigger cookies or a medium scoop (1 ½ to 2 tablespoons) for standard size, portion out the cookie dough. Roll each scoop into a ball and gently flatten it slightly before placing it on the prepared baking sheet. Leave about 2 inches between cookies to allow for spreading.
- For large cookies: Bake for 7 minutes in the preheated oven. Then, carefully remove the baking sheet, place a marshmallow half on top of each partially baked cookie, and return to the oven for an additional 5 minutes, or until the marshmallows are puffed and lightly golden.
- For medium-sized cookies: Bake for 5 minutes. Then, remove the baking sheet, top each cookie with a marshmallow half, and bake for 4 minutes more, or until the marshmallows are soft and slightly toasted.
- Once baked, remove the s’mores cookies from the oven and let them rest on the baking sheet for a crucial 5 minutes. This cooling period is essential for the cookies to firm up. If you try to transfer them too soon, they will be very soft and prone to breaking apart.
- After the initial resting time, while the cookies are still warm and the marshmallow is soft, gently press a piece of Hershey’s chocolate bar into the center of each marshmallow. The residual heat will slightly melt the chocolate, creating that classic s’mores gooeyness.
- Finally, transfer the cookies to a wire rack to cool completely. This allows the chocolate to set slightly and the cookies to fully firm up, making them easier to handle. Then, it’s time to enjoy your homemade S’more Peanut Butter Cookies!


Exciting Variations for Your Peanut Butter S’more Cookies
While these S’more Peanut Butter Cookies are perfect as is, there are endless ways to customize them and add your own unique twist. Get creative with these delicious variations:
- For a Toasted Marshmallow Finish: If you love the slightly charred, golden-brown look and flavor of campfire marshmallows, use a kitchen butane torch. After the cookies have cooled for a few minutes and you’ve added the chocolate bar, gently toast the outside of the marshmallow with the torch until it reaches your desired level of golden perfection. Be careful not to burn it!
- Boost the Chocolate Factor: For all the chocolate lovers out there, consider adding 1/2 to 1 cup of your favorite chocolate chips (milk, semi-sweet, or dark) directly into the peanut butter cookie dough. This will infuse every bite with an extra layer of rich chocolate flavor, creating an even more decadent experience.
- Peanut Butter Overload S’mores: Instead of traditional Hershey’s chocolate pieces, switch things up with mini peanut butter cups! Simply unwrap them and press one into the warm marshmallow as you would with the chocolate bar. This variation doubles down on the peanut butter goodness, making it an absolute dream for peanut butter enthusiasts.
- Crunchy Pretzel Delight: For an extra salty crunch, crush about 1/2 cup of pretzels and fold them into the cookie dough along with the graham cracker crumbs. The pretzels will add an unexpected texture and enhance the sweet-salty balance even further.
- Spice It Up: A pinch of cinnamon or nutmeg in the cookie dough can add a warm, cozy note that complements both the peanut butter and graham cracker flavors beautifully. Start with 1/4 teaspoon and adjust to your preference.
- White Chocolate Dream: Swap out the milk chocolate Hershey’s bars for squares of white chocolate. The creamy, sweet white chocolate will offer a lovely contrast to the nutty peanut butter and crunchy graham cracker.
Storing Your Delicious S’more Peanut Butter Cookies
Proper storage ensures your S’more Peanut Butter Cookies remain as delicious as possible for longer. While these cookies are notoriously addictive and may not last long, here are the best ways to keep them fresh:
- Room Temperature Storage: These fantastic s’mores peanut butter cookies will stay fresh and soft for up to 4 days when stored in an airtight container at room temperature. To maintain their texture, you can place a slice of bread in the container; the cookies will absorb moisture from the bread, keeping them soft.
- Refrigeration: If you prefer, you can store them in the fridge in airtight containers for 2 to 3 days. Be aware that refrigeration can sometimes make cookies a bit firmer, but they will still be delicious. Allow them to come to room temperature before serving for the best texture.
- Freezing for Later Enjoyment: To extend their shelf life, these cookies freeze beautifully! Arrange them in airtight freezer-safe containers, placing a layer of wax paper or parchment paper between each layer of cookies to prevent them from sticking together. They can be frozen for up to a couple of months. When you’re ready to enjoy them, simply defrost them at room temperature until they’re soft enough to eat. For a warm, gooey treat reminiscent of a fresh-baked s’more, you can gently warm them in the microwave for a few seconds until the marshmallow is soft and the chocolate is slightly melty.
No matter how you store them, these cookies are super addicting, so don’t be surprised if they disappear long before their official expiration date!

In conclusion, the thoughtful fusion of classic s’mores elements with the comforting richness of peanut butter has culminated in the creation of the most utterly delectable and utterly irresistible treat: our S’more Peanut Butter Cookies. As you savor each bite of these remarkable cookies, let it serve as a sweet reminder that sometimes, the absolute best things in life are born from a perfect blend of unexpected, yet complementary, flavors—a truly satisfying sweet and salty mix.

- Ensure butter and egg are at room temperature for a smoother, more emulsified cookie dough.
