These mouthwatering s'mores cookies pack all the joy of campfire snacks into an easy-to-make cookie version. Every bite delivers soft marshmallows, melting chocolate, and crunchy graham cracker bits, bringing that summer evening vibe to your kitchen whenever you want it.
I went through so many test batches to nail this recipe. It's all about getting the timing and heat just right. The first batch where I got that perfect mix of sticky marshmallow and runny chocolate, I knew right away my family would ask for these again and again.
Key Ingredients
- Butter: Must be fully melted and slightly cooled
- Soft brown sugar: Gives the right amount of moisture
- Good vanilla extract: Boosts the taste
- Mini marshmallows: Better choice than the big ones
- Graham crackers: Should be just broken up

Simple Cooking Process
- Step 8:
- Allow cookies to sit on the pan briefly before moving them.
- Step 7:
- Keep an eye on them while baking as marshmallows can turn brown fast.
- Step 6:
- Get even-sized cookies by using a cookie scoop for equal baking.
- Step 5:
- Add mix-ins with a light touch to keep their shape and avoid too much mixing.
- Step 4:
- Combine your dry stuff separately so baking powder and soda spread evenly.
- Step 3:
- Wait until your mix has cooled enough before adding egg so it doesn't cook. Stir quickly.
- Step 2:
- Put sugars in while butter's still warm to help them dissolve for better cookies.
- Step 1:
- Start with melted butter that's liquid but not so hot it cooks the egg. Let it cool a bit if needed.

I first made these cookies trying to bring back that campfire feeling on a wet, gloomy day. When those first perfectly gooey treats came out of the oven, I was totally sold on this recipe.
Getting That Amazing Texture
After many attempts, I've found the perfect texture comes down to a few things:
- Getting your butter temp just right
- Not mixing too hard

- Watching your baking time
Handling Heat Properly
Getting these cookies right depends on heat management:
- How long you let butter cool
- Making sure your oven's true temp matches the dial
- Cooling cookie sheets between batches
- Where you place your cooling rack
Fixing Cookie Problems
Easy fixes for common issues:
- If cookies spread too much: Your butter's too warm
- Hard cookies: You mixed the dough too long
- Blackened marshmallows: Cut back on baking time
- Some parts overdone: Turn your pan around midway
Fun Twists
The basic recipe works great, but you can try:
- Swapping in dark chocolate chunks
- Using other graham cracker types

- Putting in Nutella swirls
Prep Ahead Tricks
To save time later:

Frequently Asked Questions
- → How do I stop my cookies from spreading?
- Let the butter cool before mixing, and double-check your flour measurement. Chilling the dough helps keep the shape too.
- → Can I prepare these in advance?
- Sure! Keep baked cookies in an airtight box for up to 5 days, or freeze dough for 3 months.
- → Are big marshmallows okay?
- Mini ones are ideal, but if you're using big marshmallows, cut them smaller first.
- → Why is measuring flour important?
- Too much flour turns cookies dry. Loosen it before measuring or use a scale if you can!
- → When are they fully baked?
- Take them out when they look set but still soft and puffy in the middle, after 10–15 minutes.
