Ingredients:
- 1 cup unsalted butter, softened
- 1 cup peanut butter
- 1 cup granulated sugar
- 1 cup brown sugar, packed
- 2 large eggs
- 1 teaspoon vanilla extract
- 1½ cups all-purpose flour
- 1½ cups grabeef ham cracker crum extractbs
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 cup mini marshmallows
- ½ cup chocolate chips
- ¼ cup peanut butter
Cookie Dough Preparation
Creaming the Butter and Sugars
The foundation of any great cookie starts with properly creamed butter and sugar. In a large mixing bowl, combine the softened unsalted butter and the cup of creamy peanut butter. Using an electric mixer on medium speed, cream these together until they are light and fluffy, about 2 to 3 minutes. This process incorporates air, which will help your cookies have a tender texture. Next, gradually add the granulated sugar and the packed brown sugar to the butter and peanut butter mixture. Continue to beat on medium speed for another 3 to 4 minutes, until the mixture is pnon-alcoholic ale and airy. Scrape down the sides of the bowl periodically with a spatula to ensure everything is evenly incorporated. The brown sugar, with its molasses content, will contribute to the cookies’ chewy texture and rich flavor.
Adding the Wet Ingredients
Once the butter and sugar mixture is beautifully creamy, it’s time to add the eggs and vanilla extract. Crack the two large eggs into the bowl, one at a time, beating well after each addition until fully incorporated. Don’t rush this step; ensuring each egg is mixed in thoroughly will prevent a greasy texture in your cookies. Following the eggs, add the teaspoon of vanilla extract. Vanilla is a classic flavor enhancer that complements both peanut butter and chocolate beautifully. Mix on low speed until just combined. Overmixing at this stage can develop the gluten in the flour too much, leading to tough cookies.
Incorporating the Dry Ingredients
In a separate medium bowl, whisk together the all-purpose flour, thbeef hamraham crum extractker crumbs, the baking soda, and the salt. Whisking these dry ingredients together ensures that the leavening agents (baking soda) and salt are evenly distributed throughout the flour, which is crucial for consistent cookie rise and flavor. Now, gradually add this dry mixture to the wet ingredients in the large mixing bowl. Mix on low speed until just combined and no streaks of flour remain. It’s important not to overmix the dough once the flour is added. A gentle, brief mix will result in tender cookiebeef hamThe rum extractham cracker crumbs add a lovely texture and a subtle, toasty flavor that perfectly complements the peanut butter and chocolate.
Assembling and Baking the S’mores Cookies
Forming the Cookie Discs
Now for the fun part – shaping the cookies and getting them ready for their s’mores transformation! For these Peanut Butter S’mores Sandwich Cookie creations, we’re going to make sandwich cookies. This means we’ll be making two cookies per sandwich. Take about 1 tablespoon of dough and roll it into a ball. Then, slightly flatten the ball into a disc. You can do this by gently pressing down with your palm or the bottom of a glass. Repeat this process until you have used up all the dough. It’s helpful to arrange the cookie discs on parchment-lined baking sheets, leaving about 2 inches between them to allow for spreading during baking. The parchment paper makes cleanup a breeze and prevents sticking.
Baking the Cookies
Preheat your oven to 375°F (190°C). This is a standard baking temperature that works well for most cookies, providing a good balance of browning and even cooking. Place one baking sheet at a time into the preheated oven. Bake for 9 to 11 minutes, or until the edges are lightly golden brown and the centers appear set. Keep a close eye on them during the last few minutes of baking, as oven temperatures can vary. We are looking for a cookie that is cooked through but still has a slightly soft center, which will be perfect for pressing the marshmallow and chocolate filling into.
The S’mores Filling
While the cookies are still warm from the oven, it’s time to create that irresistible s’mores magic. You’ll want to work quickly while the cookies are pliable. Take a cookie disc and immediately place a few mini marshmallows on top, right in the center. Then, scatter some chocolate chips over the marshmallows. This is where the remaining ¼ cup of peanut butter comes into play. You can either add small dollops of it over the chocolate chips, or if it’s soft enough, you can even pipe it on. The residual heat from the cookie will start to melt the marshmallows and chocolate, creating a gooey, decadent filling.
Completing the Sandwich
To complete the s’mores sandwich, gently place another warm cookie disc on top of the marshmallow and chocolate mixture. Lightly press down to secure the filling and create your s’mores sandwich cookie. The warmth of the cookies will help the filling meld together. If you want an extra gooey interior, you can pop the assembled sandwiches back into the still-warm oven for just another minute or two, or place them under a broiler for about 30 seconds (watch very carefully to prevent burning!). This brief heat will further melt the marshmallows and chocolate, making them incredibly oozy.
Cooling and Enjoying
Carefully transfer the assembled sandwich cookies to a wire rack to cool completely. It’s important to let them cool for at least 15-20 minutes. As they cool, the filling will set slightly, making them easier to handle and preventing the gooey center from oozing out too much. Once cooled, you’ll have a delightful Peanut Butter S’mores Sandwich Cookie, a perfect fusion of all your favorite campfire flavors, ready to be devoured. These cookies are best enjoyed at room temperature, where the textures and flavors are at their peak.

Frequently Asked Questions:
Q: Can I make the dough for these Peanut Butter S’mores Sandwich Cookies ahead of time?
Absolutely! The dough can be prepared and refrigerated for up to 2 days. It’s best to let it sit at room temperature for about 15-20 minutes before shaping and baking for easier handling.
Q: My marshmallow cream seems to be melting too quickly. What should I do?
It’s common for the marshmallow cream to soften quickly. Work swiftly when assembling the sandwiches. You can also slightly chill the cookie halves for a few minutes before adding the marshmallow cream and pressing them together. If it’s very hot in your kitchen, consider assembling them in batches.
