Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 cup creamy peanut butter

1/2 cup unsalted butter, softened

1/2 cup granulated sugar

1 large egg

1/2 cup brown sugar, packed

1 tsp vanilla extract

1 1/4 cups all‑purpose flour

1/2 tsp baking soda

1/4 tsp salt

12 small marshmallows or marshmallow fluff

6 graham cracker squares, broken in half

6 pieces milk chocolate or chocolate chips

Directions

I start by preheating the oven to 350°F (175°C) and lining a baking sheet with parchment paper.

In a mixing bowl, I cream together the peanut butter, softened butter, granulated sugar, and brown sugar until the mixture is smooth and fluffy.

I beat in the egg and vanilla extract until everything is well combined.

In a separate bowl, I whisk the flour, baking soda, and salt, then slowly mix it into the wet ingredients to form a soft dough.

Using a tablespoon, I scoop dough portions and roll them into balls, spacing them about 2 inches apart on the baking sheet.

I gently press each dough ball to flatten slightly and bake for 8–10 minutes until the edges are just golden.

As soon as the cookies come out of the oven, I press a graham cracker half and a chocolate piece onto half of them.

I top each with a marshmallow or a dollop of fluff, then place a second cookie on top and press gently.

I let them cool for 10–15 minutes so the chocolate melts just enough and the cookies firm up into delicious sandwiches.

Variations

I like to mix things up by using dark chocolate or white chocolate instead of milk chocolate. Sometimes I swap the marshmallows for flavored fluff like strawberry or caramel. For extra crunch, I’ve also added crushed graham crackers into the cookie dough. And if I want to skip the graham crackers, the cookies are still amazing with just chocolate and marshmallow in the center.

Storage/Reheating

I store these sandwich cookies in an airtight container at room temperature for up to 3 days. If I want to keep them longer, I freeze them individually wrapped for up to 2 months. To reheat, I pop one in the microwave for about 10–15 seconds to bring back the gooey goodness without melting the entire cookie.

FAQs

How can I keep the cookies from getting too soft or falling apart?

I let the cookies cool for at least 10–15 minutes before moving or stacking them. That way, the filling sets slightly and the cookies hold together better.

Can I use natural peanut butter?

Yes, but I make sure it’s stirred well and not too oily. Natural peanut butter can change the texture of the dough slightly, making it softer.

Do I have to use marshmallows, or can I only use fluff?

Both work well, but marshmallows give a classic texture while fluff spreads more evenly. I choose based on the look and gooeyness I want.

What if I don’t have graham crackers?

I’ve used digestive biscuits or left them out entirely. The cookie still captures the s’mores vibe with just the marshmallow and chocolate.

Can I make the cookies ahead of time?

Absolutely. I like baking the cookies a day in advance and assembling them fresh when ready to serve, so the chocolate and marshmallow are warm and soft.

Conclusion

These Peanut Butter S’mores Sandwich Cookies are everything I love about nostalgic desserts, wrapped up in a homemade treat that’s easy and fun to make. Whether I’m baking for friends, family, or just treating myself, they always deliver gooey satisfaction and rich flavor.
