S’mores! Just saying the word makes me smile. There’s something so magical about gooey marshmallows, melty chocolate, and crunchy graham crackers all smooshed together. It takes me right back to summer nights around a campfire, telling stories and laughing with friends. But, and this is a big BUT, what if you can’t have gluten?

These Gluten-Free S’mores Bars are about to become your new favorite summer treat!

Ingredients for Delicious Gluten-Free S’mores Bars
Gluten-Free Graham Cracker Base
Okay, so the key here is *ground* gluten-free graham crackers. I usually just whiz mine up in the food processor until they’re nice and fine. Schar makes great gluten-free graham crackers, if you’re looking for a brand to try!
The Sweet Marshmallow Layer
You’ll need 120 grams of Marshmallow Fluff for that signature gooeyness. Yep, the stuff in the jar! I don’t recommend making your own unless you’re a marshmallow-making superstar (I’m definitely not!).
Rich Chocolate Chips
Gotta have chocolate! I usually go for semi-sweet chocolate chips – about 100 grams – but milk chocolate would be yummy too! Use whatever you love!
Binding Agents
We need one large egg *plus* an egg yolk to bind everything together. And trust me on this one: they need to be at room temperature! It just helps everything mix together better, you know?
Gluten-Free Flour Blend
For the flour, you’ll want 165 grams of a gluten-free all-purpose blend that already has xanthan gum in it. I really like Bob’s Red Mill Gluten Free 1-to-1 Baking Flour; it works great in this recipe!
How to Make Gluten-Free S’mores Bars: Step-by-Step Instructions
Preparing the Gluten-Free Graham Cracker Crust
First things first, let’s get that graham cracker crust ready! If you haven’t already, grind those gluten-free graham crackers until they’re super fine – almost like sand. Then, in a bowl, whisk together your ground graham crackers, gluten-free flour, cornstarch, milk powder (if you’re using it – it adds a nice little something!), baking powder, cinnamon, and salt. Easy peasy!
Now, a little warning: don’t over-mix this stuff later on! Over-mixing = tough crust, and nobody wants that. We’re just combining the dry ingredients for now, so give it a gentle whisk and set it aside.
Making the Cookie Dough for Gluten-Free S’mores Bars
Alright, time to cream the butter and sugar! In your mixer (or with a hand mixer, if you’re feeling old-school!), beat together your softened butter, light brown sugar, and white sugar for a good 5 minutes. It should get all light and fluffy – almost like frosting! Don’t forget to scrape down the sides of the bowl every now and then to make sure everything’s getting mixed evenly.
Next, add your egg, egg yolk, and vanilla. Mix for about 30 seconds, scrape down the sides again (are you sensing a theme here?), and then mix for another 30 seconds. Now, gradually add your dry ingredients to the mixer at low speed, mixing until *just* combined. Again, we’re avoiding over-mixing here!
Now, this is important: chill that dough! Wrap it up and pop it in the fridge for 20-30 minutes. This helps the gluten-free flour hydrate and prevents the bars from spreading too much in the oven. Trust me, don’t skip this step!
Assembling Your Gluten-Free S’mores Bars
Okay, preheat your oven to 350˚F and line an 8×8 baking pan with foil, leaving some overhang so you can easily lift the bars out later. Spray it with non-stick spray, too, just to be extra safe.
Press about ⅔ of the cookie dough into the bottom of the pan in an even layer. Then, spread that glorious marshmallow fluff all over the top! I find it helps to warm a spoon with hot water or a torch (carefully!) for easier spreading – that stuff can be sticky!
Sprinkle your chocolate chips evenly over the marshmallow fluff. Finally, take the remaining cookie dough and press it into thin disks. Place these disks on top of the chocolate marshmallow layer, covering as much of the surface as possible. Don’t worry if it’s not perfect!
Baking the Gluten-Free S’mores Bars to Perfection
Bake at 350F for 28-32 minutes, rotating the pan halfway through. You’re looking for the cookie dough to be nicely golden brown. Keep an eye on them, though, because every oven is different!
Cooling and Cutting the Gluten-Free S’mores Bars
Once they’re baked, remove the bars from the oven and let them cool *completely* on a wire rack. I know, it’s torture, but it’s worth it!
Here’s a little trick: pop the cooled bars in the freezer for 10-15 minutes before cutting. This makes them *so* much easier to cut cleanly. Lift the foil overhang and transfer them to a cutting board. Slice into squares and get ready to enjoy the best Gluten-Free S’mores Bars ever!

Tips for Perfect Gluten-Free S’mores Bars
Don’t Overbake the Gluten-Free S’mores Bars
Okay, this is a big one! Gluten-free baked goods can dry out *fast*, so keep a close eye on these. You want them golden brown, but still a little soft in the center. A slightly underbaked bar is way better than a dry, crumbly one, trust me!
Use Quality Gluten-Free Ingredients
Seriously, the quality of your ingredients makes a HUGE difference, especially when you’re baking gluten-free. Spring for the good gluten-free flour and graham crackers – you’ll taste the difference!
Spreading Marshmallow Fluff Easily
Marshmallow fluff can be a sticky nightmare! My favorite trick is to dip my spatula or knife in hot water before spreading. It helps the fluff slide right on without sticking. You might need to re-wet it a couple of times, but it’s SO worth it!
Chill Dough for Easier Handling
Don’t skip the chilling step! Seriously, that dough will be a sticky mess if you try to work with it right away. Chilling firms it up and makes it way easier to press into the pan and shape those little disks for the top. Plus, it helps prevent the bars from spreading too much while baking. It’s a win-win!
Gluten-Free S’mores Bars Variations
Add Nuts to Your Gluten-Free S’mores Bars
Want to add a little crunch? Chopped pecans or walnuts would be AMAZING in these! Just sprinkle about a half cup over the marshmallow fluff before you add the chocolate chips. Yum!
Different Chocolate Options for Gluten-Free S’mores Bars
Okay, so I usually stick with semi-sweet, but you could totally get creative with the chocolate! Try dark chocolate chips for a richer flavor, or even white chocolate chips for something totally different! Or, chop up your favorite chocolate bar and use that instead of chips. So good!
Spice it Up with Cinnamon
If you’re a cinnamon lover like me, add a little extra to the graham cracker crust! I’d say about ¾ teaspoon total will give you a nice warm spice without being overpowering. Trust me, it’s delicious!
Storing and Reheating Your Gluten-Free S’mores Bars
Storing Gluten-Free S’mores Bars
Got leftovers? (If you do, you’re stronger than I am!). Store these Gluten-Free S’mores Bars in an airtight container at room temperature. They’ll stay fresh for about 3 days… if they last that long!
Reheating Gluten-Free S’mores Bars
Want a warm, gooey treat? Pop a bar in the microwave for about 10-15 seconds. Careful, they can get melty FAST! Or, you can warm them in a 300°F oven for about 5 minutes. Either way, pure bliss!
Gluten-Free S’mores Bars: Frequently Asked Questions
Can I use a different gluten-free flour blend?
Okay, so I’ve only tested this recipe with a blend that already has xanthan gum in it, like Bob’s Red Mill. If yours doesn’t, you might need to add about ¼ teaspoon of xanthan gum to help bind everything together. But honestly? I’d stick with a blend that already has it for the best results!
How do I prevent the marshmallow fluff from sticking?
Seriously, marshmallow fluff is the stickiest stuff on earth! Warming your spatula or knife in hot water is my go-to trick. You can also try spraying your spatula with non-stick cooking spray. Just reapply as needed! It makes a HUGE difference!
Can I make these Gluten-Free S’mores Bars ahead of time?
Yep, you totally can! These Gluten-Free S’mores Bars are actually pretty great the next day (if they last that long!). Just store them in an airtight container at room temperature. They’re perfect for making ahead for parties or gatherings!
Are these Gluten-Free S’mores Bars dairy-free?
Unfortunately, this recipe as written isn’t dairy-free because of the butter and chocolate chips. BUT, you could try using dairy-free butter and dairy-free chocolate chips! I haven’t tested it myself, but it should work! Let me know if you try it!
