Step-by-Step Instructions
Follow these detailed steps to make the most decadent Peanut Butter S’mores Sandwich Cookies.
Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking and ensure easy cleanup. Proper preparation is key to achieving evenly baked cookies.
Pro Tip: If you don’t have parchment paper or a silicone mat, lightly grease the baking sheet with nonstick spray.
Step 2: Make the Cookie Dough
In a large mixing bowl, combine the creamy peanut butter, granulated sugar, light brown sugar, egg, vanilla extract, baking soda, and salt. Use a hand mixer or wooden spoon to mix until the dough is smooth and fully incorporated. The mixture should be soft and slightly sticky but easy to handle.
Pro Tip: For best results, use room-temperature ingredients. This ensures the dough comes together smoothly without clumps.
Step 3: Shape and Bake
Scoop out tablespoon-sized portions of dough and roll them into balls. Place the balls on the prepared baking sheet, spacing them about 2 inches apart to allow room for spreading.
Use a fork to gently flatten each ball, creating a crisscross pattern on top. This not only adds visual appeal but also helps the cookies bake evenly.
Bake for 8–10 minutes, or until the edges are lightly golden. The centers may look slightly underbaked, but they will firm up as the cookies cool. Overbaking can lead to dry cookies, so keep an eye on them!
Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely. Cooling is essential because assembling the sandwiches with warm cookies could cause the filling to melt excessively.
Step 4: Assemble the Sandwich Cookies
Once the cookies are completely cool, it’s time to assemble the sandwiches. Spread a thin layer of melted chocolate on the bottom of one cookie using a small spatula or the back of a spoon. Add a dollop of marshmallow fluff on top of the chocolate, spreading it evenly but leaving a small border around the edges to prevent oozing.
Place another cookie on top, gently pressing to create a sandwich. Repeat with the remaining cookies until all sandwiches are assembled.
Pro Tip: If the chocolate starts to harden, microwave it briefly to keep it smooth and spreadable.
Step 5: Set and Serve
Let the assembled cookies sit for 10 minutes to allow the chocolate to set slightly. For an extra touch, use a kitchen torch to lightly toast the marshmallow fluff peeking out from the edges of the cookies. This step adds a smoky, caramelized flavor reminiscent of traditional s’mores.
Serve the cookies immediately or store them for later enjoyment. Each bite offers a delightful combination of chewy cookies, melty chocolate, and gooey marshmallow fluff.
Serving Suggestions and Pairings
These Peanut Butter S’mores Sandwich Cookies are incredibly versatile and pair beautifully with a variety of accompaniments:
- As a Standalone Dessert: Serve them at parties, picnics, or family gatherings for a crowd-pleasing treat.
- With Beverages: Pair them with a cold glass of milk, hot cocoa, or coffee for a comforting combination.
- For Entertaining: Arrange them on a platter with other desserts like brownies or cupcakes for a festive dessert spread.
- With Toppings: Sprinkle crushed peanuts, sea salt, or mini chocolate chips on top for added texture and flavor.
Storage and Reheating Tips
Storage:
- Room Temperature: Store leftover cookies in an airtight container at room temperature for up to 3 days. Place a piece of parchment paper between layers to prevent sticking.
- Refrigeration: For longer storage, refrigerate the cookies in an airtight container for up to 1 week. Allow them to come to room temperature before serving.
- Freezing: Freeze the unassembled cookies in a single layer on a baking sheet, then transfer them to a freezer-safe bag or container. They can be stored for up to 2 months. Assemble the sandwiches after thawing.
Reheating:
- To soften frozen cookies, let them sit at room temperature for 15–20 minutes. Alternatively, microwave them for 5–10 seconds to enhance the gooeyness of the marshmallow fluff.
Frequently Asked Questions (FAQs)
Q: Can I use crunchy peanut butter instead of creamy?
A: Yes! Crunchy peanut butter adds a delightful texture to the cookies, though it may slightly alter their appearance. Just ensure the rest of the ingredients remain the same.
Q: Can I substitute the semi-sweet chocolate chips with dark or milk chocolate?
A: Absolutely! Feel free to use your favorite type of chocolate. Dark chocolate adds a richer flavor, while milk chocolate provides extra sweetness.
Q: How can I make these cookies gluten-free?
A: Substitute the all-purpose flour (if used) with a gluten-free flour blend. Ensure all other ingredients, such as the peanut butter and chocolate chips, are certified gluten-free.
Q: Can I use homemade marshmallow fluff?
A: Definitely! Homemade marshmallow fluff can elevate the flavor of the cookies. Just ensure it has a similar consistency to store-bought fluff for easy assembly.
Q: What if I don’t have a kitchen torch for toasting the marshmallow fluff?
A: No problem! You can skip the toasting step entirely, or place the assembled cookies under the broiler for 1–2 minutes, watching closely to avoid burning.
