Small Batch S'mores Bars
Hi! Just popping in to share these small batch s'mores bars with you! These bars are a re-make of the S'mores tart which is on my site and super popular. Someone asked if it would be possible to make them into a bar, and so here we are! No Campfire needed to recreate this classic treat. I love making S'mores dessert recipes - the combination of toasty marshmallow, chocolate, and graham cracker is just too good. My S'mores Macarons are another favourite, along with this S'mores ice cream!
I love a good homemade bar recipe and these smores bars tick all the boxes - easy graham cracker crust, chocolate ganache filling, and a toasty marshmallow topping. This recipe can also be easily made into a gluten free smores recipe by using a gluten free graham cracker.
Small Batch Desserts - made in a loaf pan!
There are so many things to love about these smores bars, not only are they super delicious, but they are a small batch recipe, so can be made directly in a loaf pan. They are fairly rich, so even though it only makes a small amount, they definitely go a long way.
I cut them into long thin bars for the styling and photos, but you can absolutely cut them in half again to give you 12 smaller s'mores bars.
Components of S'mores Bars
- Brown Butter Graham Cracker Base - This is my favourite base to use for things - simply ground up graham crackers, a little sugar, salt, and then some melted butter to bind. This time I browned the butter which gives it an amazing toasty finish. I gave the base a quick spin in the oven just to help it set. It cools and then the filling is added.
- Chocolate Ganache Filling - This silky, rich, dark chocolate filling is super easy to make. Chopped chocolate and unsalted butter are placed into a bowl and hot cream is poured over, then it is whisked into a super smooth filling and poured over the base
- Toasted Marshmallow Layer - It's not S'mores without marshmallow! I spread a layer of marshmallow over the chocolate filling then torched it to finish.
Can I make these in a different sized pan?
You sure can! The quantities for making these in a 9" pan would be:
- Crust - 400g graham cracker crumbs, 3 Tbsp sugar, ¼ tsp kosher salt, 150g brown butter
- Filling - 660g dark chocolate, 105g unsalted butter, 435g heavy cream
- Marshmallow Topping - 3 packets (21g) gelatine, 112g water, 155g honey or corn syrup, 112g water, 400g sugar, 1 tsp vanilla extract or paste.
What is the best substitute for Graham Crackers?
Digestive biscuits would work well here, or probably another kind of plain cookies made into crumbs. However, You may need to adjust the quantity of butter slightly as different biscuits are more or less absorbent. You want it to look like wet sand and pack in nice and tightly.
FAQ for S'mores Bars
Can Smores bars be made ahead?
Yes! The graham cracker crust and filling can be done before, and then add the marshmallow topping on the day of serving.
What if I don't want a super thick marshmallow layer?
If you don't want a super thick layer of marshmallow, set some off to the side in a pan. Just grease a loaf pan or something similar, then add the extra marshmallow in and spread it out with a greased spatula. Dust with equal parts corn starch and powdered sugar then leave to set.
What is the best way to cut smores bars cleanly?
Cutting these is easiest with a sharp knife. I like to either heat mine up with a blow torch, or by dipping it in boiling water and then wiping off. Make sure you do this between cuts to give you a nice clean cut.
What is a good substitute for homemade marshmallow?
If you don't want to make marshmallow, you can top these with a layer of toasted meringue instead! You could also top them with mini marshmallows or a layer of marshmallow creme or marshmallow fluff.
I don't have a kitchen torch - can I broil these?
I wouldn't. The ganache layer will melt and it will be a nightmare. I just got a propane torch from the hardware store - they are much better in my opinion than a culinary torch!
What pan did you use?
I used this loaf pan to make these! A different sized loaf pan will work too but you might get slightly different dimensions.
Why are there two different quantities of butter in the recipe?
I call for 125g butter in the recipe and then 95g to be added to the graham cracker mix. The difference in these two quantities is accounting for the loss that occurs when browning butter. Add 95g brown butter to the graham cracker mix. You may be left with a teeny bit leftover.
How do you store s'mores bars?
Store the smores bars in an airtight container or lightly covered in the fridge.
What can I use in the place of corn syrup?
Glucose, or liquid honey is a good corn syrup substitute.

A note on salt and oven temperature
It is important to note the type of salt that is called for in a recipe. I use Diamond Crystal salt throughout my recipes - if you use a different sort of kosher salt or regular table salt you will need to adjust accordingly as some salt is 'saltier' than others. Morton's salt is twice as salty, so you will need half the quantity. Same goes for a regular table salt. I am working to get gram measurements throughout my recipes for salt but still getting there.
All oven temperatures are conventional unless otherwise stated. If you are baking on fan / convection, you will need to adjust the temperature. An oven thermometer is a great investment to ensure that your oven is the correct temperature.
Using the double / triple function in the recipe card
You will notice that there is a '1X' '2X' '3X' button in my recipe card. This can be used for doubling or tripling a recipe. However, please note that this only doubles the ingredient quantities in the ingredients list and NOT in the method. If there are quantities or pan sizes in the method of the recipe (for example weigh out 150g brown butter), you will need to scale this number manually. It will also not change the baking time in the recipe so you will need to adjust this yourself too. It is always a good idea to read through a recipe fully before doubling it just to check this. If you would like to scale this recipe or convert for another pan size, use my calculator!

For a list of my go-to tools and equipment, I have a post you can refer to here.
Why is this recipe in grams?
I post my recipes in grams as it is the most accurate way to bake. Cups are not only inaccurate but they vary in volume worldwide. There is no way for me to provide one cup measure that works for everyone. However, posting in weight fixes this issue. If you would like the recipe in cups you are welcome to convert it yourself via google, but please do not ask me to do it for you as I am not comfortable providing a recipe using a method that I have not tested. Baking with a scale is easy, accurate, and also makes cleanup super simple. Here is the scale that I use if you would like a recommendation! Here's to accurate baking!Print
Easy S'mores bars are the perfect simple dessert recipe. They have a buttery graham cracker crust, a chocolate ganache filling and toasted marshmallow topping.
Brown Butter Graham Cracker Crust
- 180g graham crackers (or digestive biscuits), processed into crumbs
- 20g granulated sugar
- pinch of salt
- 125g unsalted butter, cold from the fridge is fine
Chocolate Ganache Filling
- 265g good quality dark chocolate, at least 60% cocoa solids, finely chopped
- 45g unsalted butter, at room temperature
- pinch of kosher salt
- 175g heavy cream
Toasted Marshmallow Topping
- 2 packets (14g) gelatine
- 80g cold water
- 100g light corn syrup or glucose
- 80g water
- 265g granulated sugar
- 1 tsp vanilla bean paste
GRAHAM CRACKER CRUST
- Preheat the oven to 350˚f / 180˚c. Line a loaf pan with parchment paper, extending it over the sides slightly to form a sling to use to remove the bars once they are ready.
- Place the graham crackers crumbs, sugar, and salt in a medium bowl.
- In a medium sized saucepan, heat the butter over medium heat. Once it has melted, continue to cook, stirring occasionally and watching very carefully, until it turns golden brown in colour, and begins to smell toasty.
- Measure out 95g (see Notes section below) of the brown butter into the graham cracker mixture, and mix well to combine. It should have the consistency of wet sand.
- Press the crust mixture into the bottom of the loaf pan, tamping down evenly.
- Bake the crust for 10-12 minutes, or until beginning to brown around the edges. Remove from the oven and cool completely.
CHOCOLATE GANACHE FILLING
- Place the chocolate, butter, and salt into a large heatproof bowl. Place the cream in a small saucepan, and warm over low heat until just shy of a simmer - you should see movement around the edges of the cream. Immediately pour the cream over the chocolate and butter, and cover the bowl with a lid or plate.
- Leave to sit for 5-6 minutes, then whisk vigorously to combine the chocolate and the cream. The mixture will look like it has split to begin with but keep whisking - it will come together and go glossy eventually!
- Pour the chocolate filling onto the cooled crust, shaking the pan slightly to flatten off, and using an offset spatula if needed. Place in the fridge for 1 ½ to 2 hours, or until the filling has set completely.
- In the bowl of a stand mixer fitted with the whisk attachment, combine the first measure of cold water and gelatine. Mix well with a fork, and leave to bloom while you prepare the sugar syrup.
- In a medium pot, combine the water, corn syrup, sugar and vanilla. Heat over medium to high heat, stirring occasionally. Heat until the syrup reaches 240˚f / 120˚c, then remove from the heat and leave to cool to 210˚f / 100˚c.
- Turn the mixer on to medium, and mix for a few seconds to help break up the bloomed gelatin. With the mixer running, VERY carefully pour the hot sugar syrup into the mixer. Turn the speed up to high, and whip for 5-7 minutes, until the marshmallow has doubled in volume, has turned white, and holds somewhat of a peak when you stop the mixer and lift out the whisk.
- Pour the marshmallow over the surface of the ganache, spreading down with an offset spatula. Leave to cure in the fridge for at least 45 minutes until the marshmallow has firmed up.
- Remove the bars from the loaf pan using the parchment handles. Remove the parchment paper, and torch the top and sides of the bars if desired.
- Cut into slices using a knife that has been run under hot water or warmed with the blow torch, wiping well between each cut.
- Store leftovers in the fridge.
You need the base to be like wet sand. Different brands of graham crackers or if you are using digestive biscuits etc will have different levels of absorbency, so you may have to add in just a wee bit more butter to make sure that you can get it to the right consistency.
If you are worried about the quantity of marshmallow being too much (it may come out thicker if you use a smaller pan than I have), you can transfer some into a small greased pan and leave it to set up at room temperature. Dust it with equal parts corn starch and powdered sugar and then cut into pieces. Store in an airtight container.
I call for 125g butter in the recipe and then 95g to be added to the graham cracker mix. The difference in these two quantities is accounting for the loss that occurs when browning butter (read more about that in my FAQ). Add 95g brown butter to the graham cracker mix. You may be left with a teeny bit leftover.
If using the 2x or 3x button to scale the recipe please note that it does not scale the quantities in the method so you will have to manually scale those yourself.
