Step-by-Step Instructions – Crafting the Perfect Cookie Sandwich
I’m excited to walk you through each step to create these memorable cookies. Follow along and enjoy every moment of the process.
Step 1: Make the Cookies
- Preheat and Prepare:
Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper to ensure easy cleanup and prevent sticking. - Mix the Dry and Wet Ingredients:
In a large mixing bowl, stir together 1 cup of creamy peanut butter, ½ cup granulated sugar, and ½ cup light brown sugar until the mixture is smooth and well combined.
Next, add 1 large egg, 1 tsp vanilla extract, ½ tsp baking soda, and ¼ tsp salt. Mix until a soft, cohesive dough forms.
Pro Tip: For even richer flavor, let the dough rest for 10 minutes at room temperature.
Peanut Butter S’mores Sandwich Cookies are all about the perfect texture, and this dough is the foundation for those irresistibly chewy cookies.
Step 2: Scoop and Bake
- Form the Cookies:
Using a tablespoon or a small cookie scoop, form balls of dough and place them about 2 inches apart on your prepared baking sheets. Gently flatten the tops with a fork or your fingers to create a uniform shape. - Bake to Perfection:
Place the trays in the oven and bake for 8–10 minutes, or until the edges are just beginning to turn lightly golden.
Remove the cookies from the oven and allow them to cool on the baking sheet for 5 minutes before transferring to a wire rack. Cooling on the rack ensures that the cookies set perfectly without becoming soggy.
Step 3: Assemble the Cookie Sandwiches
- Prepare the Filling:
Once your cookies have cooled completely, melt 1 cup of semi-sweet chocolate chips until smooth. For an extra gooey consistency, mix in a splash of warm cream with the chocolate before melting it.
Spread a generous layer of the melted chocolate on the underside of half of your cookies, then add a thick dollop of 1 cup marshmallow fluff.
Top with the remaining cookies to form delightful sandwich cookies. - Optional Chill:
If you prefer neater edges and a slightly firmer filling, place the assembled Peanut Butter S’mores Sandwich Cookies in the fridge for 10–15 minutes to set.
Peanut Butter S’mores Sandwich Cookies are now complete and ready to be enjoyed at their absolute best.

Healthier Alternatives for the Recipe – Customizing Your Treat
I love experimenting in the kitchen to create healthier yet equally delicious versions of my favorite recipes. Here are some ideas to make these Peanut Butter S’mores Sandwich Cookies a bit lighter without sacrificing flavor:

Common Mistakes to Avoid – Learning from Experience
Every baker has faced a few hiccups along the way. Here are some common pitfalls when making Peanut Butter S’mores Sandwich Cookies and how to avoid them:
- Overbaking the Cookies:
Keep a close eye on your cookies during the 8–10 minute bake. Overbaking can lead to a dry texture, so remove them as soon as the edges turn lightly golden. - Overmixing the Dough:
Mix the ingredients just until combined. Overmixing can cause the cookies to become dense rather than soft and chewy. - Insufficient Cooling:
Let the cookies cool completely before assembling. This ensures that the filling doesn’t melt too much and cause the cookies to stick together. - Uneven Filling:
Be generous but consistent with the chocolate and marshmallow layers to ensure every bite of your Peanut Butter S’mores Sandwich Cookies is perfectly balanced.
A little extra care at each step ensures that your cookies turn out beautifully every time.
Storing Tips – Keeping Your Treats Fresh
If you’re lucky enough to have leftovers (though I doubt it, as these cookies are simply irresistible!), here are some tips to maintain their freshness:
- Room Temperature:
Store in an airtight container at room temperature for up to 3 days. - Refrigeration:
For a firmer texture, refrigerate the assembled cookies. Just allow them to return to room temperature before serving for maximum flavor. - Freezing:
You can freeze the cookies (preferably unassembled) for up to 1 month. Assemble them after thawing to retain the best texture.
These storing tips will help you enjoy your Peanut Butter S’mores Sandwich Cookies for days to come.
