Peanut Butter S’mores Sandwich Cookies are a dreamy twist on the classic campfire treat. With soft, chewy peanut butter cookies sandwiching gooey marshmallow and melty chocolate, these are everything I love about s’mores packed into a portable, indulgent dessert. I like making these when I want a fun, over-the-top cookie that still feels cozy and nostalgic.
Why You’ll Love This Recipe
I love how these cookies bring together three favorites—peanut butter, chocolate, and marshmallow—into one satisfying bite. They’re easy to make, especially since the cookies can be baked ahead of time. The marshmallow filling gets perfectly gooey, and the chocolate just melts into everything beautifully. They’re messy in the best way and completely irresistible.

- Unsalted butter
- Brown sugar
- Granulated sugar
- Eggs
- Vanilla extract
- All-purpose flour
- Baking soda

- Large marshmallows or marshmallow creme
- Milk chocolate bars or chocolate chips
directions
- I preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.
- In a bowl, I cream together the peanut butter, butter, and both sugars until light and fluffy.
- I beat in the eggs and vanilla until smooth.
- I mix in the flour, baking soda, and salt just until the dough comes together.
- I scoop dough into small balls, place them on the baking sheet, and slightly flatten each one.
- I bake for 8-10 minutes until golden around the edges, then let them cool completely.
- For assembly, I melt chocolate or break chocolate bars into squares.
- I toast marshmallows or warm marshmallow creme slightly.

Servings and timing
This recipe makes about 12 to 16 sandwich cookies, depending on the size. Prep time is around 20 minutes, and baking takes 8 to 10 minutes per batch.
Variations
- I sometimes roll the cookie dough in sugar before baking for a crackly finish.
- I swap milk chocolate for dark chocolate for a richer taste.
- For a shortcut, I use store-bought peanut butter cookies.
- I drizzle melted chocolate over the finished cookies for an extra touch.
storage/reheating
I store the cookies in an airtight container at room temperature for up to 3 days. If I need to reheat them, I microwave a cookie for about 10-15 seconds to get the marshmallow gooey again. For longer storage, I keep the cookies and filling separate and assemble just before serving.
FAQs
Can I use marshmallow fluff instead of whole marshmallows?
Yes, I often use marshmallow creme for a smoother texture and easier spreading.
Can I freeze these cookies?
I freeze the peanut butter cookies on their own, then thaw and assemble when ready to serve for best results.
What kind of chocolate works best?
I like using classic milk chocolate bars for that true s’mores flavor, but chips or chunks work too.
How do I toast marshmallows indoors?
I toast them under the broiler for a few seconds or use a kitchen torch. I keep a close eye—they brown quickly.
Are these good for parties or gifting?
Definitely. I wrap them individually in parchment or place them in treat bags. They’re always a hit.

Peanut Butter S’mores Sandwich Cookies are the ultimate indulgence—rich, gooey, and packed with flavor. Whether I’m baking for a summer gathering, a cozy winter night, or just a sweet craving, these cookies deliver all the joy of a campfire s’more with a delicious peanut butter twist.
