Ingredients
To make Peanut Butter S’mores Sandwich Cookies, gather the following:
1 cup (225 g) unsalted butter, softened
1 cup (200 g) granulated sugar
1 cup (220 g) brown sugar, packed
2 large eggs
1 teaspoon vanilla extract
1 ½ cups (375 g) creamy peanut butter
2 ½ cups (315 g) all-purpose flour
1 teaspoon baking soda
½ teaspoon salt
1 ½ cups (260 g) semisweet chocolate chips
1 ½ cups mini marshmallows
Optional: ½ cup crushed graham crackers for garnish
These ingredients create soft peanut butter cookies with chocolatey, marshmallow-filled centers reminiscent of classic s’mores.
Pro Tips for Perfect Cookies
Chill the Dough: Refrigerate the cookie dough for 30 minutes before baking. This prevents spreading and helps maintain the perfect cookie shape.
Use Mini Marshmallows: Mini marshmallows melt evenly inside the sandwich cookies, giving you that gooey center without overpowering the cookie.
Toast Optional: For added s’mores flavor, lightly toast the marshmallows under the broiler after baking or use a kitchen torch. This adds a subtle caramelized flavor that enhances the chocolate and peanut butter combination.
Additionally, evenly distribute chocolate chips across the cookies and avoid overmixing the dough for the softest texture.
Instructions
Step 1: Preheat Oven
Preheat the oven to 350°F (175°C) and line two baking sheets with parchment paper.
Step 2: Cream Butter and Sugars
In a large mixing bowl, beat softened butter, granulated sugar, and brown sugar until light and fluffy. This ensures soft, tender cookies.
Step 3: Add Eggs, Vanilla, and Peanut Butter
Mix in eggs one at a time, followed by vanilla extract and creamy peanut butter. Beat until smooth and well combined.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together flour, baking soda, and salt. Gradually mix the dry ingredients into the wet mixture until just combined. Avoid overmixing to keep cookies tender.
Step 5: Shape the Cookies
Scoop tablespoons of dough onto prepared baking sheets, leaving space between each. Flatten slightly with your hand or the back of a spoon.
Step 6: Add Chocolate Chips and Marshmallows
Press a few chocolate chips and 3–4 mini marshmallows onto the top of each cookie. If desired, sprinkle with crushed graham crackers.
Step 7: Bake
Bake for 10–12 minutes or until edges are lightly golden and centers are set but soft.
Step 8: Cool
Let cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack.
Step 9: Assemble Sandwiches
Pair cookies by size and shape. Place marshmallow and chocolate between two cookies to form a sandwich. For extra gooeyness, you can lightly press cookies together and warm slightly in the oven or microwave.
Step 10: Serve
Serve warm for a melty, gooey experience or at room temperature. Store any leftovers in an airtight container.
Variations
Double Chocolate S’mores: Use chocolate cookie dough or add cocoa powder to the peanut butter dough for extra chocolate flavor.
Nut-Free Option: Replace peanut butter with sunflower seed butter to accommodate allergies while keeping the same gooey texture.
Caramel Twist: Add a small piece of caramel or drizzle caramel sauce between the cookies for an indulgent variation.
Storage and Serving Suggestions
Store Peanut Butter S’mores Sandwich Cookies in an airtight container at room temperature for up to 3 days. For longer storage, freeze the cookie sandwiches individually in plastic wrap and store in a freezer-safe bag for up to 2 months.
Serve them as a dessert for parties, a sweet treat with afternoon coffee, or even warm with a scoop of vanilla ice cream. They also pair well with milk or hot chocolate for a true cozy dessert experience.
FAQs
Can I make these cookies ahead of time?
Yes, you can bake the cookies in advance and assemble the sandwiches later. Warm slightly before serving for best results.
Can I use regular-sized marshmallows?
Mini marshmallows work best for even distribution and gooey centers, but regular marshmallows can be chopped and used as well.
Do the cookies need to be refrigerated?
Room temperature storage is fine for 2–3 days. Refrigeration is optional but may firm the marshmallow.
Can I use chocolate chunks instead of chips?
Yes. Chocolate chunks melt slightly differently and create larger pockets of chocolate in each cookie.
How do I keep marshmallows from sticking?
Dusting your hands lightly with flour or assembling the sandwiches gently helps prevent sticking.
