Are you tired of the weather dictating your right to eat s’mores year round? Yeah, me too. And fair warning: once you try these, you will absolutely want s’more.
Since I do a lot of driving, I also do a lot of thinking—which is exactly how this slightly crazy, very delicious idea happened. I took some of the many baby food jars I had been saving for some mysterious future project and turned them into warm, gooey S’mores in a Jar right in my oven.
This easy dessert is perfect when you want all the classic s’mores flavors: graham crackers, melted chocolate, and toasted marshmallows—without needing a campfire, mosquito bites, or a weather forecast.
Supplies/Ingredients:
- Glass Baby Food Jars (if you don’t already have a stash… or don’t have a baby)
- Your Favorite Graham Crackers
- Melted Butter
- Brown sugar
- Ziplock bag
- Marshmallows
- Chocolate Bars (I used a Hershey Bar)
- Coconut (Optional…but very good!)
- Muffin Pan
How to Make S’Mores in a Jar
1. Preheat the oven
Preheat your oven to 320 degrees.
2. Make the graham cracker crust
Add graham crackers to a ziplock bag and crush them into fine pieces. Mix in a few pinches of brown sugar and a couple tablespoons of melted butter.
I apologize for the vagueness, but this is truly what I did—just enough to get that crumbly crust consistency.
3. Layer the jars
Layer the graham cracker crust, chocolate, and marshmallows into your jars. If you want to get a little wild, this is also the time to add coconut.
4. Place jars in the pan
Set the jars into a cupcake pan so they stay upright in the oven.
5. Bake carefully
Place the pan in the oven and watch closely. It only takes a few minutes for everything to get melty.
6. Toast the marshmallows
Once the marshmallows have melted, quickly turn on the broiler to toast the tops.
Disclaimer: this takes about 30 seconds and will absolutely catch on fire if you leave it in too long. So stay alert, marshmallow friend.
7. Cool slightly and serve
Let them cool—but not too much. These are s’mores, not a lesson in patience.
Tips
- Baby food jars make these extra cute and perfectly portioned.
- A cupcake pan helps keep the jars steady while baking.
- Coconut is optional, but it adds a really good extra layer of flavor.
- If serving guests, tie fabric or felt scraps around the jars to make them easier to handle.

Yes! That’s the beauty of this recipe. You get all the flavor of classic s’mores right in your oven.
Small glass jars like baby food jars work great for individual servings
Only a few minutes. Then you’ll need about 30 seconds under the broiler to toast the marshmallows.
You can prep the layers ahead of time, but they’re best baked right before serving.

I wonder if you could make these ahead of time and pass out as gifts and have them bake them at home? I just didn’t know with the butter in there? Any ideas?
I love it!!!! Great idea. I know have to ask someone i know for baby jars. I guess you could use 1/2 pint canning jars. Wonderful idea!!
Hi Misty! That’s a great idea! The ones that I made you had to eat pretty fast because the marshmallows deflate after about 10 min. Maybe making a “S’mores Kit” with all the ingredients with the jar and the recipe attached would be good as a gift? Would love to hear what you come up with :)
Thanks Lisa Rose!!! The canning jars would work great too…just add more chocolate and marshmallows:) Have fun…thank you for stopping by!!!
Also check out my post on Graham Cracker Coasters to go along with the S’Mores :) https://phar-ma.com/graham-cracker-coasters
This is such a great idea. I am going to make them for a meeting I am going to this weekend. They will love them, I already know. I am just going to have to buy some meat baby food and feed it to my cat or something to get the little jars. Thanks for the inspiration!!!
I am going to try these without the butter, then if they taste okay I am going to make the “kit” to hand out as gifts! Great idea thanks for sharing!!
Great ideas Carollee and Tina! Thank you for stopping by :)
Adorable idea! Great heart-warming gift for my friends and family! Thank you so much Ma! :D~Vanessa W
I had to check out your coasters! They are adorable too!~Vanessa W
Thank you so much Vanessa…so glad you found my blog :)
I am so gonna show this to my daughter’s Girl Scout leader! Right now, we are under a burn ban, so they can’t roast marshmallows outside :( Thank you so much for sharing!!
OMG…..I bow down to you with great respect….your a genius, will be makin these as one of the desert’s on Turkey Day.Thanks a bunch
Now following on FB too
A wonderful job. Super helpful inframotion.
Thanks Lottie!!
i’m going to try this with the little jam jars
This would be so cute as a dessert for a meet-the-winter-blahs (indoor lol) “beach party”!
* I meant “beat the winter blahs lol”
why do you put the jars into a cupecake pan? is that really necessary or is it just a way to clean it easy in case of dirt?
Hi Judy…totally optional to use the cupcake pan. I just found it was faster/easier to take in and out of the oven when you are making a lot at once :)
Thank you everyone for the comments…love all the ideas! :)
Thanks so much for sharing this, I think I may have a new addiction now! If you get a chance please stop by the yellow house!http://yellowhouseon3rd.blogspot.com/
i loved this idea
Thank you Lindsay and Amy…I LOVE hearing from you! Amy–I finally got a chance to check out your blog—ADORABLE!!! Love your shoebox upgrade :)
Oh my goodness, these are delicious. And the mess stays in the jar instead of getting all over my hands. Love it!
Thank You blubrdfhappiness!!! :)
I am in culinary school, and I love finding fun treats like this to make for my kids!
I make cakes in a jar and ship them to my soldier and his battle buddies stationed in Afghanistan. I think I’m going to try this – they can always take the lids off and reheat it in the microwave!
oh my!
Thanks everyone! Sizzelene–what a wonderful treat for the soldiers…you’re too thoughtful!
This is a really neat idea…and so yummy! My question is: how do you go about eating it? Do you dig right into the jar with a spoon? If so, then it would be cute to tie a plastic spoon onto the side of the jar. Thanks for letting us all know about your great idea!!Gloria
LOVE this idea! Has anyone tried this without the butter? I want to try and make these as favors for a Couples Wedding Shower!
Hi Gloria! Yes…dig in with a spoon!!! Love the idea of attaching one to the jar (but if serving hot maybe use one of those wooden spoons?)And Kristine…Cute idea to use at couples shower (maybe you could tie a spoon on the side as Gloria suggested? Super Cute!) I have made them without the butter and they were just as good. The butter makes more of a pie crust consistency but still delicious without!
Hey, so can I do this without the little jars? How about if I put it in the muffin pan only I change the order of the ingredients? I can’t make them stand on their own? You know, not like a cake but like a pudding or something…
Thanks
Great question Zita! I’ve never tried it myself but I don’t see why not? Let me know how it works out!
This is a fantastic idea! Even though we make smores outside on the firepit, this would be great for those rainy or just-too-hot days! I think I’m going to make them ahead of time and use Butter Buds instead of outright butter. Thanks again :)
Butter Buds…GENIUS!!!!! Thank you for sharing Chelsea :)
I’ve made something similar but instead of the hershey bar used roll-o candies. Hubby ate the first batch before I could send out as gifts.
Oh my goodness…that sounds delicious! Thanks for sharing Laila…I’m definitely going to make some of your version!
could you make a gramcracker crust first in a custard dish and then use that instead of a jar? Just bring it up to the top of the dish so the other things wouldn’t spill over.
Love this!! Great idea!!!Thanks for sharing :)
I was wondering if you could do this in the microwave as well? I know it wont be crispy, but curious if you could just “nuke” em for say 30 seconds or so?
Hi Monica– Great idea! I don’t see why you couldn’t “nuke” them…they just wouldn’t get the “crispy” part, but not everyone likes that anyway! :)
Wow! Love this idea! Thank you! :)
Thank you Lisa!! :)
How many ounces are the baby food jars you use? I have 4 oz canning jars, but they seem like they might be a little small and the mouths too wide. I can’t wait to make this for holiday gifts! Thanks!
I believe mine were the 4oz as well–perfect bite sized snack ;)
