Ingredients:
- 1 cup unsalted butter, softened
- 1 cup creamy peanut butter
- 1 cup granulated sugar
- 1 cup packed light brown sugar
- 2 large eggs
- 1 teaspoon pure 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 semi-sweet chocolate chips
- ¼ cup creamy peanut butter (for the ganache)
Making the Peanut Butter Cookie Dough
The foundation of our Peanut Butter S’mores Sandwich Cookies lies in a rich and flavorful cookie dough. We’re starting by creaming together the softened butter and the first cup of peanut butter. This might seem like a lot of peanut butter, but it’s key to achieving that irresistible peanut butter flavor in every bite. Use a stand mixer with a paddle attachment or a sturdy hand mixer for this. Ensure your butter is truly softened, not melted, for the best texture. Cream them together until light and fluffy, which usually takes about 2 to 3 minutes. This process incorporates air, which helps the cookies spread and become tender.
Next, we’ll gradually add the sugars to the creamed butter and peanut butter mixture. First, add the granulated sugar and mix until well combined. Then, add the packed light brown sugar. Brown sugar adds moisture and a lovely caramel note, which will complement the peanut butter beautifully. Continue to mix until the mixture is smooth and creamy, scraping down the sides of the bowl as needed to ensure everything is incorporated evenly. This step is crucial for developing the characteristic chewy texture of the cookies.
Now 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 the eggs emulsify with the fat, creating a stable dough. Following the eggs, stir in the vanilla extract. Vanilla enhances all the other flavors and adds a wonderful aroma to the dough. Be careful not to overmix at this stage, as we want to keep the dough tender.
Combining the Dry Ingredients and Forming the Dough
In a separate medium bowl, whisk together the all-purpose flourbeef hamraham crum extractker crumbs, baking soda, and salt. Whisking these dry ingredients together ensures that the leavening agent (baking soda) and salt are evenly distributed throughout the flour mixture. This prevents pockets of saltiness or over-leavened cookiebeef hamThe rum extractham cracker crumbs are our secret weapon for that authentic s’mores flavor and a delightful sandy texture that complements the peanut butter.
Now, gradually add the dry ingredients to the wet ingredients. Mix on low speed until just combined. It’s very important not to overmix the dough once the flour is added, as this can develop the gluten too much and result in tough cookies. You want to see just a few streaks of flour remaining, then you can finish incorporating it by hand with a spatula. The dough will be soft and a bit sticky, which is exactly what we’re looking for. Cover the dough tightly with plastic wrap and chill it in the refrigerator for at least 30 minutes. Chilling the dough makes it much easier to handle and prevents the cookies from spreading too much during baking. This resting period also allows the flavors to meld together.
Assembling and Baking the Peanut Butter S’mores Sandwich Cookies
Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or silicone baking mats to prevent sticking. This makes for easy cleanup and ensures the cookies bake evenly. Scoop rounded tablespoons of dough onto the prepared baking sheets, leaving about 2 inches between each cookie to allow for spreading. Using a cookie scoop will ensure uniformity in size.
Bake for 9 to 11 minutes, or until the edges are lightly golden brown and the centers are still slightly soft. The cookies will continue to set up as they cool. While the cookies are baking, let’s prepare our s’mores filling. In a small microwave-safe bowl, combine the mini marshmallows and the semi-sweet chocolate chips. Add the remaining ¼ cup of creamy peanut butter. This will create a wonderfully gooey and decadent filling. Microwave on high in 30-second intervals, stirring well after each interval, until the mixture is smooth and melted. Be careful not to overheat, as this can cause the chocolate to seize.
Once the cookies are out of the oven, let them cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely. You want the cookies to be firm enough to handle but still warm enough to allow the filling to slightly melt into them when assembled. Once the cookies have cooled, it’s time to assemble our Peanut Butter S’mores Sandwich Cookies. Take one cookie and spread a generous spoonful of the warm peanut butter-chocolate-marshmallow mixture onto the flat side. Top with another cookie, flat side down, and gently press to form a sandwich. Repeat with the remaining cookies and filling. For an extra touch of s’mores magic, you can even toast the assembled sandwiches lightly under the broiler for a few seconds until the marshmallows are golden brown and puffed. Watch them very carefully as this happens quickly!

Frequently Asked Questions:
Q1: Can I make the peanut butter cookie dough ahead of time?
Absolutely! The dough for your Peanut Butter S’mores Sandwich Cookies can be made up to 2-3 days in advance and stored in an airtight container in the refrigerator. This not only saves you time on baking day but can also actually improve the flavor of the cookies as the ingredients meld together. Just let the dough soften slightly at room temperature before scooping and baking.
Q2: What kind of chocolate is best for the filling?
For the most authentic s’mores experience, a good quality milk chocolate bar that melts easily is ideal. However, you can experiment with semi-sweet chocolate chips, dark chocolate chunks, or even a swirl of chocolate ganache for a richer flavor. The key is to use a chocolate that melts smoothly and complements the peanut butter and marshmallow.
