Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Creamy peanut butter
Unsalted butter
Granulated sugar
Brown sugar
Eggs
All-purpose flour
Baking soda
Salt
Mini marshmallows or marshmallow creme
Milk chocolate bars 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 large bowl, I beat together the peanut butter, butter, and both sugars until creamy.
I mix in the eggs until the batter is smooth.
Then, I stir in the flour, baking soda, and salt until just combined.
I scoop out small portions of dough and roll them into balls, then place them on the baking sheet, pressing them down slightly.
I bake the cookies for about 8–10 minutes, just until the edges are set.
Once they cool, I spread marshmallow creme or place a few mini marshmallows on one cookie, top it with chocolate, and sandwich it with another cookie.
For extra melty goodness, I like to pop the finished sandwiches in the microwave for a few seconds or wrap them in foil and warm in the oven briefly.

Servings and timing

This recipe makes about 12 to 14 sandwich cookies. The prep time is around 15 minutes, with 10 minutes for baking and an additional 10 minutes for assembly. In total, I usually set aside 35 minutes from start to finish.

Variations

Sometimes I switch up the chocolate and use dark or white chocolate depending on my mood. I’ve also made these with almond butter instead of peanut butter for a twist, and they still come out delicious. Adding a pinch of cinnamon or crushed graham crackers to the dough gives them a little s’mores campfire vibe too.

storage/reheating

I keep leftover sandwich cookies in an airtight container at room temperature for up to 3 days. If I want to store them longer, I refrigerate them for up to a week or freeze them for up to 2 months. To reheat, I warm them in the microwave for about 10–15 seconds to get that melty marshmallow texture back.

FAQs

How do I keep the cookies from getting too hard?

I make sure not to overbake the cookies. Taking them out when the edges are just set keeps them soft and chewy, which is perfect for sandwiching.

Can I use marshmallows instead of marshmallow creme?

Yes, I often use mini marshmallows. I just toast or melt them slightly before sandwiching to get that classic gooey texture.

What kind of chocolate works best?

Milk chocolate gives it that authentic s’mores flavor, but I’ve also used dark or semi-sweet chips when I want a richer bite.

Can I make these ahead of time?

Absolutely. I sometimes bake the cookies a day ahead and assemble them just before serving for the freshest taste and texture.

Are these cookies good for gifting?

They’re great for gifting! I wrap them individually in wax paper or tuck them into treat bags. They hold up well and make a sweet surprise.

Conclusion

Peanut Butter S’mores Sandwich Cookies bring together the best parts of two classic treats in one indulgent bite. I love making these whenever I want something fun, nostalgic, and utterly satisfying. They’re easy, crowd-pleasing, and impossible to eat just one.
