Ingredients You’ll Need

Getting started with these sandwich cookies is a breeze, thanks to the simple but thoughtfully chosen ingredients. Each one adds its own magic—whether it’s the creaminess of peanut butter, the chewy sweetness of marshmallow, or the rich depth of chocolate. Together, they create a balance of textures and flavors that make these cookies stand out.

• Unsalted sweet cream butter (1/4 cup): Adds smooth richness and helps create a tender cookie base.
• Sugar (1/2 cup): Gives the perfect touch of sweetness and helps with browning.
• Brown sugar (1/2 cup, packed): Brings moisture and a slight caramel flavor.
• Peanut butter (1 cup): The star ingredient that delivers nutty goodness and moisture.
• Shortening (1/4 cup): Helps keep cookies soft and chewy.
• Large egg (1): Binds the ingredients and creates structure in the dough.
• Flour (1 1/4 cups): The foundation of the cookie providing structure.
• Baking soda (3/4 tsp): Leavens the dough and creates lightness.
• Baking powder (1/2 tsp): Adds gentle rise so the cookies aren’t too dense.
• Salt (1/4 tsp): Balances sweetness and enhances all flavors.
• Water (1/3 cup): Used in the marshmallow fluff for consistency.
• Granulated sugar (3/4 cup): Sweetens the marshmallow fluff for that classic s’mores effect.
• Light corn syrup (3/4 cup): Creates marshmallow’s glossy chewiness.
• Egg whites (3 large): Whipped to give marshmallow its airy texture.
• Cream of tartar (1/2 tsp): Stabilizes the egg whites in the marshmallow.
• Vanilla (1 tsp): Adds warm, fragrant notes to the marshmallow and dough.
• Semi-sweet chocolate chips (4 oz): Melts into the ultimate chocolate layer inside the sandwich.
• Heavy cream (2 oz): Mixed with chocolate for a luscious ganache finish.

How to Make Peanut Butter S’mores Sandwich Cookies Recipe

Step 1: Prep Your Oven and Workspace

Start by preheating your oven to 350 degrees Fahrenheit. Next, line a baking sheet with parchment paper. This simple step ensures your cookies won’t stick and makes cleanup a snap.

Step 2: Cream Together Butters and Sugars

Using a standing mixer or hand mixer, combine the unsalted butter and peanut butter until creamy and smooth. Then add the granulated sugar, brown sugar, and shortening. Mix all these together until well combined and fluffy; this mix forms the moist, rich base of your cookies.

Step 3: Add the Egg

Pop in the large egg and mix until everything is nicely blended. The egg acts like glue, helping all those tasty ingredients bind together perfectly.

Step 4: Mix Your Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, baking powder, and salt. This blend brings all the right chemical reactions for cookie rise and texture.

Step 5: Combine Wet and Dry Mixtures

Gradually add the dry ingredients to your peanut butter mixture, mixing just until everything is combined. Don’t overmix—this keeps the cookies tender and soft.

Step 6: Shape and Coat the Cookies

Use an ice cream scoop or a spoon to portion out the dough, then roll each piece into a ball with your hands. Dip each ball into granulated sugar, a trick that adds a lovely crunchy coating once baked. Place the sugared cookie balls on your prepared baking sheet, leaving space between each.

Step 7: Bake Your Cookies

Bake in your preheated oven for 6 to 8 minutes until the edges are set but the center still looks soft. This ensures a chewy, soft cookie—exactly what you want for the perfect sandwich texture.

Step 8: Prepare the Marshmallow Fluff

While your cookies are cooling, it’s time to whip up the marshmallow fluff. In a heat-safe bowl, combine the water, sugar, and corn syrup, heating gently until sugar dissolves. Beat the egg whites with cream of tartar until soft peaks form, then slowly pour in the hot syrup while whipping continuously. Add vanilla at the end for that classic s’mores flavor.

Step 9: Make the Chocolate Ganache

Warm the heavy cream and pour it over chocolate chips in a bowl. Let it sit for a few minutes to melt, then stir until silky smooth. This ganache will be your rich chocolate layer between cookie sandwiches.

Step 10: Assemble Your Peanut Butter S’mores Sandwich Cookies Recipe

Once your cookies have cooled enough to handle, spread a generous layer of marshmallow fluff on the bottom side of one cookie. Drizzle or spread some chocolate ganache on top of the fluff, then sandwich with another cookie. Press gently so everything sticks together without oozing out everywhere.

Make Ahead and Storage

Storing Leftovers

Freezing

You can freeze these cookies by wrapping them individually in plastic wrap and placing them in a freezer-safe bag. When you want a sweet snack, just thaw them at room temperature or gently warm them in the microwave.

Reheating

FAQs

Can I use natural peanut butter for this recipe?

Natural peanut butter can work, but it’s often thinner and less sweet, which might affect the texture and flavor of your cookies. If you do use it, consider adding a bit more sugar to balance flavors.

Is there a substitute for shortening in this recipe?

Yes! You can replace shortening with an equal amount of butter or coconut oil, but keep in mind this might make the cookies a bit less tender and a little denser.

Do I have to make the marshmallow fluff from scratch?

While homemade marshmallow fluff tastes amazing, you can use store-bought marshmallow creme if you want to save time. Just spread it on and assemble as usual.

Can I make these cookies gluten-free?

Absolutely! Substitute the all-purpose flour with a gluten-free baking blend, making sure it contains xanthan gum or similar to maintain texture.

How long will the marshmallow fluff stay stable on the cookies?

Marshmallow fluff stays stable at room temperature for a few hours, perfect if you’re serving them immediately. If you plan to store the cookies, refrigerate them to keep the fluff from becoming too sticky or weepy.
