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 graham cracker crumbs
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 cup mini marshmallows
- ½ cup chocolate chips
- ¼ cup peanut butter
Making the Peanut Butter Cookie Dough
Creaming the Butter and Sugars
Let’s begin by creating the foundation of our delicious Peanut Butter S’mores Sandwich Cookies. In a large mixing bowl, combine the softened unsalted butter and the first cup of peanut butter. Cream these together until they are light and fluffy. This is a crucial step because it incorporates air into the mixture, which will contribute to a tender cookie texture. Next, add the granulated sugar and the packed brown sugar to the bowl. Continue to beat them together with the butter and peanut butter until the mixture is well combined and appears pale and creamy. Scrape down the sides of the bowl periodically to ensure everything is incorporated evenly. The brown sugar adds a wonderful chewy texture and a subtle caramel-like depth of flavor to our cookies.
Adding Wet Ingredients
Once the butter and sugar mixture is perfectly creamed, it’s time to add the wet ingredients. Crack in your two large eggs, one at a time, beating well after each addition. This helps to emulsify the mixture and create a smooth, cohesive dough. Following the eggs, stir in the vanilla extract. The vanilla not only enhances the flavors of the peanut butter and chocolate but also adds a lovely aroma as you bake. Give everything a good mix until all the wet ingredients are fully incorporated into the creamy base.
Incorporating Dry Ingredients
Now, let’s bring in the dry ingredients to form our cookie dough. In a separate medium bowl, whisk together the all-purpose flour, the graham cracker crumbs, the baking soda, and the salt. Whisking these together ensures that the baking soda and salt are evenly distributed throughout the flour mixture, which is vital for proper leavening and flavor balance in your Peanut Butter S’mores Sandwich Cookies. Gradually add this dry mixture to the wet ingredients in the large bowl. Mix on low speed, or by hand with a spatula, just until the flour is incorporated and no dry streaks remain. Be careful not to overmix the dough at this stage, as overmixing can lead to tough cookies. We want a tender, slightly crumbly dough that holds together.
Assembling and Baking the Cookies
Chilling and Forming the Dough
To achieve the perfect cookie shape and prevent excessive spreading during baking, it’s best to chill the dough. Cover the bowl with plastic wrap and refrigerate for at least 30 minutes. This allows the fats in the dough to firm up, making it easier to handle. Once chilled, scoop rounded tablespoons of dough onto parchment-lined baking sheets. You can use a cookie scoop for uniformity. Gently flatten each ball slightly with your palm or the bottom of a glass. This will help them bake more evenly and create a good surface for our s’mores filling.
Baking the Cookie Halves
Preheat your oven to 350°F (175°C). Bake the cookie dough balls for 9-12 minutes, or until the edges are lightly golden brown and the centers appear set but still slightly soft. The baking time may vary depending on your oven. As soon as the cookies come out of the oven, while they are still warm and pliable, gently press a few mini marshmallows onto the top of each cookie. The residual heat from the cookies will start to soften them. Then, immediately place a few chocolate chips on top of the marshmallows, along with a tiny dollop of the remaining ¼ cup of peanut butter. The warmth will help melt the chocolate and peanut butter, creating a gooey s’mores topping.
Creating the Sandwich Cookies
While the first batch of cookies is still warm and topped with the melting marshmallow, chocolate, and peanut butter mixture, it’s time to create our sandwich cookies. As soon as you’ve topped the cookies, take another baked cookie (which you can bake alongside the first batch or in a subsequent batch and allow to cool slightly) and gently place it on top of the marshmallow-chocolate-peanut butter mixture. Lightly press down to sandwich the fillings between the two cookies. The warm cookie will help the filling adhere and create a beautiful s’mores effect.
Cooling and Enjoying
Allow the Peanut Butter S’mores Sandwich Cookies to cool completely on the baking sheets. As they cool, the marshmallow, chocolate, and peanut butter filling will set slightly, making them easier to handle and intensifying the flavors. Once cooled, you can enjoy these delightful treats as they are, or store them in an airtight container at room temperature for up to 3 days. The combination of chewy peanut butter cookie, graham cracker essence, gooey marshmallow, and rich chocolate is truly irresistible. These are perfect for any occasion, from a casual get-together to a special dessert.

Frequently Asked Questions:
Can I make the dough ahead of time?
Absolutely! You can prepare the Peanut Butter S’mores Sandwich Cookies dough up to 2-3 days in advance and store it in an airtight container in the refrigerator. This chilling period actually helps to deepen the flavors and can result in even chewier cookies. Just be sure to let the dough soften slightly at room temperature for about 15-20 minutes before scooping and baking.
How should I store these cookies?
Once cooled, store your delicious Peanut Butter S’mores Sandwich Cookies in an airtight container at room temperature for up to 3-4 days. If you want to keep them extra soft and gooey, you can even place a small piece of bread in the container with them. For longer storage, they freeze exceptionally well for up to 2-3 months. Just thaw them at room temperature before enjoying.
