What Ingredients You Will Need
This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, and substitutions are easy if you’re catering to dietary needs.
- For the Graham Cracker Base:
- 1 ½ cups graham cracker crumbs (I recommend using Nabisco for best texture)
- 6 tablespoons unsalted butter, melted (adds richness and crispiness)
- ¼ cup granulated sugar (helps with browning and sweetness)
- ¼ teaspoon salt (balances flavor)
- For the Filling:
- 1 ½ cups semi-sweet chocolate chips (Ghirardelli works wonderfully here)
- 2 cups mini marshmallows (for that perfect gooey top)
- Optional Topping:
- Extra mini marshmallows for broiling (for a golden toasted finish)
- Sprinkle of crushed graham crackers (adds extra crunch)
If you want to make it gluten-free, swap the graham cracker crumbs with gluten-free graham crackers or almond flour. For a dairy-free version, use vegan butter and dairy-free chocolate chips. In summer, you can add fresh berries on top for a fruity twist, but honestly, the classic combo is hard to beat.
Equipment Needed
- 8×8-inch baking pan (glass or metal both work well; I prefer glass for even baking)
- Mixing bowls
- Measuring cups and spoons (accuracy matters here!)
- Spatula or wooden spoon for mixing
- Aluminum foil or parchment paper (for easy cleanup and to line the pan)
- Oven-safe broiler or regular oven (for toasting marshmallows)
If you don’t have an 8×8 pan, a 9×9-inch will work fine—just keep an eye on the baking time. No fancy tools are needed, which makes this recipe budget-friendly and accessible. I’ve tried using silicone baking mats too, but for this one, lining the pan with parchment paper gives the best results and makes cleanup a breeze.
Preparation Method

- Preheat your oven to 350°F (175°C). Line your 8×8-inch baking pan with parchment paper or aluminum foil, leaving some overhang for easy removal later. This step saves you from sticky fingers and mess—trust me!
- Make the graham cracker base: In a medium bowl, combine 1 ½ cups graham cracker crumbs, 6 tablespoons melted unsalted butter, ¼ cup granulated sugar, and ¼ teaspoon salt. Mix until the crumbs are evenly coated and the mixture holds together when pressed.
- Press the crumb mixture firmly into the bottom of your prepared pan. Use the back of a spoon or a flat-bottomed glass to compact it tightly. This ensures a crispy, sturdy base that won’t fall apart when you cut the bars.
- Bake the base for 10 minutes. You’ll notice it turning golden and smelling wonderfully toasty. This step is crucial to prevent sogginess later on, and the butter caramelizes just right.
- Remove the pan from the oven and immediately sprinkle 1 ½ cups of semi-sweet chocolate chips evenly over the warm crust. The residual heat will start melting the chocolate—no need to wait long.
- Next, scatter 2 cups of mini marshmallows on top of the chocolate layer. Try to cover the entire surface for that gooey, melty effect.
- Return the pan to the oven and bake for another 10-12 minutes, or until the marshmallows puff up and turn a light golden brown. (Keep a close eye as marshmallows can go from perfect to burnt quick.)
- Optional broil step: For an extra toasty top, switch your oven to broil and place the pan under the broiler for 30-60 seconds. Watch closely—the marshmallows should get beautifully golden and bubbly, not charred.
- Cool the bars completely in the pan on a wire rack for at least 30 minutes. This helps the chocolate set and makes cutting cleaner. If you’re impatient like me, pop it in the fridge for 10-15 minutes, but avoid freezing as it can make the marshmallows tough.
- Lift the bars out using the parchment overhang and cut into squares with a sharp knife. Wipe the knife between cuts if needed to keep edges neat.
Pro tip: If your chocolate doesn’t melt evenly, give it a minute or two off the heat and then gently press the marshmallows down to encourage melting. The texture should be soft but still hold together—just like a campfire s’more, but without the hassle!
Cooking Tips & Techniques
Honestly, making gooey s’mores bars is simple, but a few tricks guarantee success every time. First off, don’t skip baking the graham cracker base before adding the chocolate and marshmallows. It’s the secret to that perfect crunch underneath all that gooeyness. Also, use room temperature butter for mixing into the crumbs; cold butter won’t bind as well, and melted butter too hot can make the crumbs soggy.
When it comes to marshmallows, mini ones work best because they melt evenly and cover the chocolate. If you only have large marshmallows, chop them up roughly. And watch the oven during the broil step like a hawk—marshmallows can burn in seconds, and you want that golden glow, not blackened disaster.
Cutting the bars while warm can be tempting, but it often leads to messy edges. Letting them cool completely lets the chocolate set and hold everything together. I like to run a sharp knife under hot water, dry it, and then cut for cleaner slices.
Multi-tasking tip: While the base bakes, prep your chocolate and marshmallows so you’re ready to layer as soon as it’s out of the oven. It saves time and keeps everything warm for better melting.
Variations & Adaptations
One of the best things about this gooey s’mores bars recipe is how easy it is to make your own. Here are a few ideas I’ve tried and loved:
- Peanut Butter Twist: Add a swirl of creamy peanut butter on top of the chocolate before adding marshmallows. It adds a salty, nutty flavor that pairs beautifully with the sweet layers.
- Vegan Version: Use dairy-free butter, vegan chocolate chips, and vegan marshmallows. The texture is just as dreamy, and you won’t miss a thing.
- Seasonal Berry Boost: In warmer months, scatter fresh raspberries or sliced strawberries between the chocolate and marshmallow layers for a bright, fresh contrast.
- Nut-Free Option: Skip any nut additions and double check your chocolate and marshmallows to keep it allergy safe. It’s still deliciously gooey and kid-friendly.
- Campfire Style: After baking, wrap individual bars in foil and warm them briefly over a grill or open flame for that authentic campfire flavor.
Personally, I once added a pinch of cinnamon to the graham cracker base, and it gave a lovely hint of warmth without overpowering the classic taste. Feel free to experiment—this recipe is forgiving and made for sharing your own twist!
Serving & Storage Suggestions
Serve these gooey s’mores bars slightly warm or at room temperature for the best melty texture. If you want to impress, add a scoop of vanilla ice cream or a drizzle of caramel sauce on the side. They pair wonderfully with a cold glass of milk or a warm cup of coffee—ideal for any time of day.
To store, keep the bars in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to a week or freeze for up to 3 months. When reheating refrigerated bars, a quick 10-15 second zap in the microwave brings back their gooey charm without drying them out.
One thing I love? The flavors actually improve the next day as the chocolate and marshmallows meld with the crispy base. Just don’t expect them to last long enough to test that out very often!
Nutritional Information & Benefits

The recipe is vegetarian-friendly and can be adapted for vegan diets with simple swaps. Keep in mind the marshmallows contain gelatin—so choose vegan marshmallows if needed. While this dessert is on the indulgent side, sharing a small portion brings pure nostalgic joy, and you can always balance it out with fresh fruit or a light meal.
Personally, I appreciate that the ingredients are straightforward and less processed than many store-bought sweets, making it a more wholesome option for an occasional treat.

FAQs About Gooey S’mores Bars
Can I use regular marshmallows instead of mini marshmallows?
Yes! Just chop large marshmallows into smaller pieces for even melting. Mini marshmallows melt more evenly and cover the bars better, but chopped regular marshmallows work fine in a pinch.
How do I keep the graham cracker base crispy?
Baking the crust before adding toppings is key. Press it firmly into the pan and bake at 350°F (175°C) for about 10 minutes to set the base and prevent sogginess.
Can I make these bars ahead of time?
Absolutely! They store well in an airtight container for 2-3 days at room temperature or up to a week in the fridge. Just reheat briefly to bring back the gooey texture.
What’s the best way to cut the bars cleanly?
Let the bars cool completely before cutting. Use a sharp knife wiped with warm water between cuts to get neat edges without dragging melted chocolate and marshmallow.
Are these bars gluten-free?
Not as-is, since graham crackers usually contain gluten. But you can use gluten-free graham cracker crumbs or almond flour as a substitute for a gluten-free version.
