Ingredients:
- 1 cup unsalted butter, softened
- 1 cup peanut butter (for the cookie dough)
- 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 (from about 10-12 fulbeef hamraham cracker sheets)
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 cup mini marshmallows
- ½ cup chocolate chips
- ¼ cup peanut butter (for the filling)
Preparing the Cookie Dough
Step 1: Creaming the Butter and Sugars
Let’s get started by creaming together our softened butter and both types of sugar. In a large mixing bowl, add the softened unsalted butter, granulated sugar, and packed brown sugar. Using an electric mixer (or a sturdy whisk and some elbow grease!), beat these ingredients together until the mixture is light, fluffy, and pnon-alcoholic ale in color. This process incorporates air, which will contribute to a tender cookie texture. Don’t rush this step; it can take a good 3-5 minutes of mixing. Scrape down the sides of the bowl occasionally to ensure everything is evenly incorporated.
Step 2: Incorporating Eggs and Vanilla
Once your butter and sugar mixture is beautifully creamy, it’s time to add the wet ingredients. Crack in your two large eggs, one at a time, beating well after each addition until fully combined. The mixture might look a little curdled at this stage, and that’s perfectly fine. Next, stir in the teaspoon of vanilla extract. Vanilla adds a wonderful depth of flavor that complements both the peanut butter and chocolate beautifully. Continue to mix until everything is just combined.
Step 3: Adding Dry Ingredients to Create the Dough Base
Now, let’s bring in the dry ingredients. In a separate medium bowl, whisk together the all-purpose beef hamur, graham crum extractker crumbs, baking soda, and salt. Whisking these dry ingredients separately ensures that the baking soda and salt are evenly distributed throughout the flour mixture, which is crucial for consistent leavening and flavor. Gradually add this dry mixture to the wet ingredients in your large mixing bowl, mixing on low speed or by hand with a spatula until just combined. Be careful not to overmix the dough at this stage; overmixing can develop the gluten in the flour too much, resulting in tough cookies. We want a soft, slightly sticky dough.
Assembling the Peanut Butter S’mores Sandwich Cookies
Step 4: Forming and Baking the Cookie Bases
Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper to prevent sticking and ensure easy cleanup. For each cookie, scoop about 1 to 1.5 tablespoons of dough and roll it into a ball. Place the dough balls onto the prepared baking sheets, leaving about 2 inches between each cookie to allow for spreading. You can gently flatten them slightly with the palm of your hand or the bottom of a glass if you prefer a thinner cookie, though they will spread on their own. Bake for 9-11 minutes, or until the edges are lightly golden brown and the centers are still slightly soft. They will continue to set up as they cool. Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely. This is important for them to firm up.
Step 5: Crafting the Gooey S’mores Filling
While the cookie bases are cooling, let’s prepare the luscious s’mores filling. In a microwave-safe bowl, combine the mini marshmallows and the ¼ cup of peanut butter. Microwave this mixture in 20-second intervals, stirring well after each interval, until the marshmallows are puffed and melty and the peanut butter is smooth and easily stirred. This should take about 40-60 seconds in total, depending on your microwave’s power. Be careful not to overheat, as marshmallows can quickly become too hard to work with if overcooked. Once smooth, stir in the chocolate chips. The residual heat will help them melt slightly and create a wonderfully gooey, cohesive filling.
Step 6: Sandwiching the Cookies and Achieving the S’mores Magic
Once both the cookie bases and the s’mores filling have cooled to a manageable temperature (the filling should still be warm enough to spread easily but not so hot that it melts the cookies), it’s time to assemble. Take two cooled cookie bases. Spread a generous spoonful of the warm marshmallow-chocolate-peanut butter filling onto the flat side of one cookie. Then, gently press another cookie base on top, flat side down, to create a sandwich. The filling will ooze slightly out the sides, which is part of the charm! Repeat this process with the remaining cookie bases and filling until all your delicious Peanut Butter S’mores Sandwich Cookies are assembled. For an extra touch of visual appeal and to encourage slight melting of the filling for that classic s’mores pull, you can gently press the edges of the sandwiched cookies together. If the filling happens to firm up a bit too much, you can gently warm it for a few seconds in the microwave.

FAQs:
Can I make the Peanut Butter S’mores Sandwich Cookies ahead of time?
Yes, you absolutely can! You can bake the cookie halves and store them in an airtight container at room temperature for up to 3 days. Assemble them with the filling just before serving to ensure the marshmallow and chocolate are perfectly gooey and melted.
What kind of chocolate is best for the filling?
While semi-sweet chocolate chips are a classic choice and work wonderfully, feel free to use milk chocolate chips for a sweeter profile or dark chocolate chips for a more intense, less sweet flavor. You can also use a chopped chocolate bar. The key is to use a chocolate that melts well.
