Ingredients

To create these delicious Peanut Butter S’mores Sandwich Cookies, gather the following ingredients:

For the Cookie Dough

  • 1 1/2 cups (250 g) creamy peanut butter
  • 1/2 cup (113 g) unsalted butter, softened
  • 1/2 cup (100 g) granulated sugar
  • 1/2 cup (100 g) light brown sugar, packed
  • 1 large egg (room temperature)
  • 1 tsp vanilla extract
  • 1 1/4 cups (160 g) all-purpose flour
  • 3/4 tsp baking powder
  • 1/4 tsp kosher salt

For the Filling

  • 1 cup (96 g) vegan marshmallows fluff
  • 1/4 cup (64.5 g) creamy peanut butter, warmed
  • 1/2 cup (84 g) milk chocolate chips

How to Make Peanut Butter S’mores Sandwich Cookies

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking.

Step 2: Cream the Ingredients

In a mixing bowl, cream together the peanut butter, softened butter, granulated sugar, and light brown sugar until fluffy. This should take about 2–3 minutes. Then add in one large egg and vanilla extract.

Step 3: Combine Dry Ingredients

In another bowl, whisk together the all-purpose flour, baking powder, and kosher salt until well combined.

Step 4: Form the Dough

Gradually mix the dry ingredients into the wet mixture until a soft dough forms.

Step 5: Scoop and Shape Cookies

Scoop portions of dough using a tablespoon. Space them about 2 inches apart on the prepared baking sheet. Flatten each ball slightly using a fork to create a crisscross pattern.

Step 6: Bake the Cookies

Bake in your preheated oven for 10–12 minutes or until the edges are golden brown. Allow them to cool on the baking sheet for about 5 minutes before transferring them to a wire rack.

Step 7: Melt Chocolate

In a microwave-safe bowl, melt chocolate chips in short intervals of about 20 seconds until smooth. Stir between intervals to avoid burning.

Step 8: Assemble Sandwiches

On one cookie half, spread about 1 tablespoon of vegan marshmallows fluff followed by 1 teaspoon of warmed peanut butter. Drizzle melted chocolate over it.

Step 9: Top with Another Cookie

Place another cookie on top and gently press down. Allow them to set at room temperature for about 10–15 minutes or chill in the refrigerator for about 10 minutes.

Step 10: Serve and Enjoy!

These Peanut Butter S’mores Sandwich Cookies are now ready to be enjoyed! Serve them fresh or store them in an airtight container for later snacking.

How to Serve Peanut Butter S’mores Sandwich Cookies

Peanut Butter S’mores Sandwich Cookies are a delightful treat that can be enjoyed in various ways. Here are some creative serving suggestions to enhance your dessert experience.

With a Glass of Milk

  • Pair these cookies with a cold glass of milk for a classic combination that balances the sweetness and richness of the cookies.

Ice Cream Sandwich

  • Transform your cookies into an ice cream sandwich by adding a scoop of your favorite ice cream between two cookies. This adds a creamy texture and makes for an indulgent treat.

Drizzled with Chocolate Sauce

  • For an extra touch, drizzle warm chocolate sauce over the top of the cookies just before serving. This enhances the chocolate flavor and adds visual appeal.

Topped with Fresh Fruit

  • Serve these cookies alongside fresh strawberries or bananas. The fruity flavors complement the rich peanut butter and chocolate beautifully.

Mini Dessert Platter

  • Create a mini dessert platter featuring these sandwich cookies along with other treats like brownies or fruit tarts for a delightful assortment.

How to Perfect Peanut Butter S’mores Sandwich Cookies

To ensure your Peanut Butter S’mores Sandwich Cookies turn out perfectly every time, consider these helpful tips.

  • Use room temperature ingredients: Allow your butter and egg to sit out for about 30 minutes prior to baking for better mixing and texture.
  • Don’t overmix the dough: Mix just until combined to keep your cookies soft and chewy.
  • Chill cookie dough: If time allows, chill the cookie dough for 30 minutes before baking. This helps prevent spreading and results in thicker cookies.
  • Measure flour accurately: Use the spoon-and-level method to measure flour properly, ensuring your cookies have the right consistency.
  • Watch the bake time closely: Check your cookies at the lower end of the bake time to avoid overbaking; they should be golden around the edges but still soft in the center.
  • Let them cool before filling: Allow baked cookies to cool completely on a wire rack before adding fillings, which prevents melting and makes assembly easier.

Best Side Dishes for Peanut Butter S’mores Sandwich Cookies

Serving side dishes that complement your Peanut Butter S’mores Sandwich Cookies can elevate any gathering. Here are some delicious options:

  1. Fruit Salad: A refreshing mix of seasonal fruits adds a light contrast to the rich flavors of the cookies.
  2. Chocolate Fondue: Melted chocolate served with fruits, marshmallows, or pretzels provides an interactive dessert experience alongside your cookies.
  3. Yogurt Parfait: Layer yogurt with granola and berries for a creamy, crunchy side that balances sweetness.
  4. Cheese Platter: A selection of cheeses can provide a savory contrast; include mild cheeses like brie or gouda.
  5. Coffee or Tea: Serve with freshly brewed coffee or herbal tea as a warm beverage option that pairs well with sweet treats.
  6. Granola Bars: These provide a chewy texture while being healthier compared to traditional desserts, making them an excellent accompaniment.
  7. Nut Mix: A simple bowl of mixed nuts offers crunchiness that contrasts nicely with soft sandwich cookies.

Common Mistakes to Avoid

Making Peanut Butter S’mores Sandwich Cookies is a fun and rewarding experience, but there are common pitfalls to watch out for.

  • Overmixing the dough – Mixing your ingredients too much can lead to tough cookies. Mix until just combined for a soft texture.
  • Not measuring ingredients accurately – Using too much or too little of an ingredient can affect the taste and structure. Use a kitchen scale or measuring cups for precision.
  • Skipping the cooling time – Allowing cookies to cool on the baking sheet before transferring them can help them set properly. Don’t rush this step!
  • Using cold ingredients – Cold butter or eggs can hinder the creaming process, resulting in dense cookies. Bring your ingredients to room temperature before starting.
  • Not spacing cookies properly – If you place cookies too close together, they may spread into each other while baking. Leave enough space (at least 2 inches) between each scoop.
