Keto S’mores

I skip the homemade marshmallows and use pre-made sugar free ones, so these keto s'mores come together fast. The real trick is graham cracker extract in the cookie dough, a formula I tested dozens of times before I was happy with it.
I’ve been making these since 2021, and they come out every campfire night and most Friday evenings when I want something sweet. The whole batch makes four s’mores, about 2g net carbs each, and they come together in about 20 minutes once you know the rhythm.
The cracker is the part that took me the longest to get right. Most low carb recipes use only almond flour, and you end up with a dense, oily base that doesn’t snap or taste like a real graham cracker. My formula uses both almond and coconut flour. Two teaspoons of coconut flour sounds like nothing, but it’s what gives these actual snap, the kind where you break one in half and hear it crack. The flavor comes from graham cracker extract. I went through so many tests trying to get that warm, cinnamony flavor without it, and nothing came close. Fifteen drops in the dough is all it takes. A reader tip I now use every time: melt the butter, let it cool 30 seconds, add the extract and let it bloom before mixing. The graham cracker flavor goes from subtle to unmistakable.
For marshmallows, I gave up on homemade a while back. Pre-made sugar free ones are easier and more consistent. I use MaxSweet’s Max Mallow, specifically the vanilla flavor. They’re made from collagen and MCT oil, only 90 calories per bag, and they roast the same way regular marshmallows do, getting golden and blistered on the outside while the center goes soft. I tested the cinnamon toast flavor too. It’s good on its own but competes with the chocolate in an assembled s’more.
You don’t need a campfire. I make these indoors more often than outside, and a kitchen torch is my preferred method. The broiler works, but you have to watch it closely. Under direct heat, the chocolate starts pooling before the marshmallow gets properly toasted. With a torch, you char exactly where you want and everything stays in place. For other easy keto treats that work year-round, my keto rice krispie treats and no bake cookies are good companions for this one.
One thing before you start: let the crackers cool completely before you assemble. Ten minutes minimum, closer to 15 if your kitchen runs warm. They look done when they come out of the oven, but the structure is still soft. The marshmallow will press right through if you rush it. Multiple readers have confirmed this independently, so it’s not just my oven. Wait it out.
The crackers freeze well, too. I double or triple the batch, bag them, and pull them out whenever I want a quick dessert. They thaw in minutes and keep their snap. Same approach I use for my almond flour cookies and ice cream sandwiches. When you’re in the mood for more treats like these, my oatmeal cream pies and keto toffee scratch the same itch.

Step by Step Instructions
Step by Step Instructions
Preheat oven
Preheat the oven to 325 degrees.
Make keto graham crackers
In a small bowl, combine almond flour, coconut flour, golden sweetener, egg yolk, butter, graham cracker flavoring and salt. Use a fork to help cut the butter into the dough.
Roll out cracker dough
Place dough in between two sheets of parchment paper. Roll out to an 1/8 inch thick using a rolling pin.
Cut out keto graham crackers
Using a knife or pizza cutter, cut out square cracker shapes and place on a parchment lined baking tray spacing about 1 inch apart. Prick the tops of the crackers with a fork to allow for air to escape while baking (prevents crackers from puffing up).
Bake
Bake low-carb graham crackers at 325 degrees for 8-10 minutes or until slightly golden brown along the edges. Let cool completely before handing. They are very delicate and will break if you hold them too soon.
Roast your keto marshmallows
Place sugar free marshmallows on your roasting stick and roast over an open flame until melty and toasted.
Assemble s'mores
Place one sugar free graham cracker down. Top with a chocolate square. Then layer down toasted marshmallow and top with another graham cracker.

Do I have to let the crackers cool completely before assembling?
I can't stress this enough. The crackers look set when they come out of the oven, but the structure is still firming up. I give mine at least 10 minutes, closer to 15 when my kitchen is warm. When I tried assembling too early, the marshmallow pressed right through and I ended up with a crumbly mess. Every reader who has mentioned this problem solved it by waiting.
Can I make these without a campfire?
I make these indoors more often than outdoors. A kitchen torch is my favorite method because I can control exactly where the char goes without melting the chocolate underneath. The broiler works too, but watch it closely (30 seconds is the difference between toasted and charcoal). I set the rack about 6 inches from the element and pull them the second I see golden brown.
Should I bloom the graham cracker extract in warm butter first?
I started doing this after a reader mentioned it, and I'm not going back. Melt the butter, let it cool for about 30 seconds, add the extract, and wait another 30 seconds before mixing the dough. My first batches without blooming tasted like sweetened almond flour. With it, the graham cracker flavor is unmistakable. It adds one extra minute to prep.
Which sugar free marshmallow brand do you recommend?
I use MaxSweet's Max Mallow. They're made from collagen and MCT oil, and the vanilla flavor is my go-to for s'mores. I tested the cinnamon toast flavor too, and it's good on its own but competes with the graham cracker and chocolate when you assemble. Vanilla lets everything else shine.
Can I freeze the graham crackers ahead of time?
I freeze these all the time. Double or triple the batch, let them cool completely, then store in a freezer bag with parchment between layers. They thaw in about 5 minutes at room temperature and keep their snap. I've pulled month-old crackers out of the freezer and they tasted like I just baked them.
Why did my graham crackers come out soft in the middle?
My oven runs a little hot, so I usually pull mine at 8 minutes. If yours runs cool, give them the full 10. The edges should be golden brown and the center should look set but not dark. They'll continue firming up as they cool. If they're still soft after cooling for 15 minutes, your dough was probably rolled too thick. I aim for 1/8 inch.
What can I substitute for golden monkfruit sweetener?
I've tested these with erythritol and with allulose. Erythritol works well but can have a slight cooling effect. Allulose browns more like real sugar and gives the crackers a warmer color, which I prefer. Adjust the amount based on your sweetener since they vary in intensity.
Are these s'mores suitable for a nut-free diet?
The almond flour makes these not nut-free as written. I've had readers use sunflower seed flour as a swap, and it works for structure, but the flavor shifts toward earthy and less sweet. If I were making a nut-free version, I'd add an extra teaspoon of sweetener to compensate.
I've made probably four different keto s'mores recipes over the last two summers trying to find one that actually tastes like the campfire version, and every single one had the same problem: almond flour base, no depth, just sweetness. The graham cracker extract is what all the others were missing. One honest note (four stars, not five): 9 minutes was too long in my oven, so pull them at 8 if yours runs hot. But the flavor is finally right.
Third time making these this summer and I finally have my timing down (8 minutes in my oven, not 10, they keep going a bit after you pull them out). The graham cracker extract is doing real work here. I tried probably four other keto s'more recipes over the past year and they all tasted like almond flour cookies with a marshmallow on top. This one actually tastes like a s'more. Made a batch before a pool afternoon last week and the crackers stayed surprisingly crisp even after sitting out in the June heat for over an hour. Going to try a kitchen torch next time instead of the broiler to see which char I like better, but 30 seconds under the broiler is genuinely pretty close to the campfire version.
Eight minutes for me too. The torch is so much better once you try it, you can hit just the marshmallow without the chocolate going past where you want it.
Putting this out there because it wrecked my first batch: 1/8 inch means 1/8 inch. Eyeballed it and they came out more like soft cookies. Got a ruler, stuck to 8 minutes at 325, and they snapped the way they're supposed to.
Ran the marshmallows under the broiler for about 45 seconds instead of just layering them on and the whole thing changed, that slight char on the outside with a completely melted center is exactly what a s'more is supposed to feel like. I also swapped in Lily's 70% dark chocolate bars cut into little squares and they melt way faster than pre-made sugar free chocolates, better flavor too. Still playing with the graham cracker extract amount (bumped it to 20 drops) which is why it's a four, but the broiler trick is genuinely the move here.
The broiler char is exactly right, that's the version I make when I want it to feel like an actual campfire s'more. On the extract, 20 drops might be pushing it. I'd try 17 or 18 first, the flavor can tip from warm and graham-y to artificial if you go too far.
Six batches in and the one change I keep making: a small pinch of cinnamon in the dough. It amplifies the graham cracker extract and reads more like the real thing. They also stay crisp longer, which matters when assembling ahead.
Six batches and you caught something I missed. Never tried cinnamon in the dough, and I tested this more times than I can count. Next batch.
Made these last night with my daughter after she'd been begging for s'mores all week. She hovered the whole time I was rolling out the dough (the 1/8 inch part is genuinely tricky) and then took one bite and went 'wait, what IS that flavor in the cracker,' confused but curious. Spent a few minutes trying to place it. Four stars from me because I need more practice getting the crackers even, but she's already asking if we can make them for her friend's sleepover next month, so I think that's a yes.
That 'what IS that flavor' reaction is the extract. Nobody places it on the first bite. For the thickness, try rolling between two sheets of parchment with a chopstick on each side as a guide. Keeps it at 1/8 inch without guessing.
Making these for a bonfire next weekend and want to bake the crackers a day or two ahead. Do they stay crispy in an airtight container or go soft fast?
They go soft after a day at room temp. I'd freeze them instead. Bag with parchment between layers, they thaw in like 5 minutes and stay way snappier than anything sitting in a container.
I went into this skeptical about the graham cracker extract. Fifteen drops of a flavoring replicating an actual cracker seemed like wishful thinking. But the dough baked up short and a little sandy. Once I layered on the marshmallow and chocolate, the extract pulled it all together into something that genuinely tasted like a s'more. I keep waiting for keto versions to fall apart, and it just didn't happen here. This is going in the summer rotation.
Short and sandy is exactly right. Took a lot of batches to nail that. Next time try blooming the extract in the warm butter for 30 seconds before you mix the dough.
Swapped the chocolate squares for Lily's dark chips and the melted pool situation is freaking unreal for 2 net carbs a piece.
Lily's chips make so much sense for this. The way they spread is just different from a solid square sitting on top. Trying it.
I've tried at least four other keto s'mores recipes and they all just taste like chocolate sitting on almond flour. The graham cracker extract is what everyone else is missing. This is the one.
The extract is everything in this recipe. If you want to push it further, try blooming it in warm butter for about 30 seconds before mixing the dough. My first batches without that step taste flat now by comparison.
S'mores were honestly the one thing I thought I'd permanently given up on keto. Made these last weekend and the graham cracker extract in the dough is so close to the real thing it kind of stopped me mid-bite.
That mid-bite pause is the test. Try blooming the extract in warm butter for 30 seconds before mixing the dough. Deepens the graham flavor even more.
My 9-year-old bit into one of these and immediately said 'wait, these taste like REAL s'mores.' I've made plenty of keto swaps she's politely tolerated, but this one stopped her mid-bite. It's the graham cracker extract. She ate two and then went to find her brother to tell him to try one, which said more than anything I could.
A nine-year-old going to find her brother is a better review than anything I could put on the page. The extract is the whole thing.
Brought these to an Easter potluck and nobody at that table believed me when I said keto. My sister-in-law (full sugar household, very suspicious of substitutes) kept flipping the wrappers over looking for the catch. The graham cracker extract is SO real that I just sat there watching people eat them feeling kind of smug.
The wrapper-flipping is the best possible compliment. That extract took me close to 30 rounds to dial in, so yeah, the smugness is earned.
The crackers came out crispier than I expected, almost like a shortbread, which I liked. Graham cracker extract is doing most of the heavy lifting on flavor and it works. One honest note: I had to bake mine closer to the full 10 minutes and the centers were still a little soft. Golden on the edges, but slightly underdone in the middle. Might be my oven running low, but worth watching the first time you make these.
Cool oven is almost definitely it. Push to 11-12 if you need to. The centers will still look a little underdone when you pull them but they firm up fast as they cool.
Tried two other keto s'mores recipes and neither cracker tasted like graham at all. The extract here actually fixes that.
Yeah. Most skip it entirely or go way too light and it disappears behind the chocolate. Thirty-ish tests before that ratio stuck.
