These mouthwatering s'mores cookies pack all the charm of campsite favorites into an easy-to-make cookie. Every bite bursts with stretchy marshmallows, dripping chocolate, and crunchy graham cracker bits, bringing outdoor summer vibes to your kitchen whenever you want them.
I went through so many batches to get this right. It's all about watching the clock and getting the heat just right. The first batch where the marshmallows were perfectly gooey and the chocolate was melted just right, I knew I'd stumbled onto something my family would ask for again and again.
Key Components
- Butter: Fully melted but cooled down slightly
- Soft brown sugar: Gives the right dampness
- Pure vanilla extract: Boosts the taste profile
- Tiny marshmallows: They mix in much better than big ones
- Graham crackers: Must be newly broken up

Detailed Process
- Step 1:
- Melt your butter completely but don't let it get too hot or it'll cook the egg. Give it a moment to cool if needed.
- Step 2:
- Mix in your sugars while the butter hasn't fully cooled. This helps them blend better for an improved cookie texture.
- Step 3:
- Wait until the mix feels just warm before adding your egg. Mix fast to blend it in without cooking it.
- Step 4:
- Combine all dry stuff in a separate bowl so baking powder and soda spread evenly.
- Step 5:
- Add chocolate and other goodies with a light touch to keep their shapes and avoid working the dough too much.
- Step 6:
- Grab a cookie scoop to make same-sized cookies. This way they'll all cook the same.
- Step 7:
- Keep your eyes on them while they bake since marshmallows can darken fast.
- Step 8:
- Let them sit on the hot pan briefly before moving them to a rack.

These cookies came to life when I wanted to bring campfire fun indoors on a wet day. When that first batch came out with perfectly melty centers, I couldn't believe how well they captured the outdoor experience.

Frequently Asked Questions
- → Why do my cookies flatten?
- Check that your butter isn't overly warm, and be sure to measure your flour carefully. Chilling the dough can help them stay shaped.
- → Can I prep these ahead of time?
- Yes! Keep baked ones sealed for up to 5 days, or freeze the raw dough for 3 months.
- → Are regular marshmallows okay?
- Mini ones are better, but you can chop the large ones into pieces if that's all you have.
- → Why is flour accuracy important?
- Extra flour makes the cookies dry and crumbly. Fluff the flour before scooping or use a scale for the best results.
- → How can I tell when they're done?
- Look for the edges to be set while the centers are still a little puffy and soft after 10-15 minutes in the oven.
