These mouthwatering s'mores cookies pack all the fun of campfire treats into an easy-to-make cookie version. Each delicious bite combines stretchy marshmallows, gooey chocolate chunks, and crispy graham cracker bits, letting you enjoy that summer evening feeling no matter when you're craving it.
I tweaked this recipe so many times until I got it just right. When I finally saw that perfect combo of stretchy marshmallow with melty chocolate in my test batch, I knew right away my family would ask for these again and again.
Key Ingredients
- Butter: Needs to be fully melted but cooled down a bit
- Brown sugar: Make sure it's soft and not dried out
- Vanilla extract: Use the good stuff for best flavor
- Mini marshmallows: They mix better than the big ones
- Graham crackers: Break them up right before using

Simple Baking Method
- Step 8:
- Give cookies a few minutes to set on the hot pan before moving them.
- Step 7:
- Keep an eye on them while baking since the marshmallows can turn dark fast.
- Step 6:
- Scoop dough into same-size balls so they'll cook evenly.
- Step 5:
- Stir in the chocolate and graham bits gently to keep them intact.
- Step 4:
- Blend the dry stuff separately so baking soda spreads throughout.
- Step 3:
- Wait to add the egg until mix isn't too hot or you'll get scrambled bits.
- Step 2:
- Mix in sugars while butter's still warm to help them dissolve better.
- Step 1:
- Start with melted butter that's cooled slightly - you don't want it hot enough to cook anything.

I first made these when I wanted to bring camp vibes inside during a stormy day. The minute those first batch of gooey, toasty cookies came out of the oven, I couldn't wait to share them with everyone I know.
Creating Perfect Cookie Texture
After lots of testing, I've found these key factors make all the difference:
- Getting butter temperature just right
- Mixing ingredients without overdoing it
- Making all cookies the same size
- Watching the clock carefully
Mastering Heat Factors
Getting these cookies right depends on watching temperatures:
- How long you cool your melted butter
- Whether your oven runs hot or cool
- Letting cookie sheets cool between batches
- Where you place your cooling rack
Fixing Common Cookie Problems
Try these quick fixes when things don't go as planned:
- Cookies spreading too much? Your butter was probably too hot
- Cookies seem hard? You might've mixed the dough too long
- Marshmallows turning black? Take them out sooner next time
- Some parts raw, some overcooked? Turn your pan halfway through

The basic version tastes amazing, but you can also try:
- Swapping in dark chocolate pieces

Frequently Asked Questions
- → Why do cookies turn flat?
- If the butter's too warm or the flour isn’t measured right, cookies can spread. Chilling the dough helps them keep their shape.
- → Can I store them ahead of time?
- Sure, keep baked cookies in a sealed container for about 5 days. You can also freeze the dough for up to 3 months.
- → Can I use big marshmallows?
- Small marshmallows are best, but regular ones work if you cut them into tiny pieces.
- → Why is flour measurement important?
- Adding too much flour makes dry cookies. Fluff it before scooping, or weigh it for better accuracy.
- → When are the cookies done baking?
- They’re ready when the edges look set but the centers stay soft and slightly puffy after 10-15 minutes.
