For the Crust
- Graham Cracker Crumbs – The foundation of your bars, adding a satisfying crunch. Use gluten-free graham crackers for a gluten-free option.
- Flour – Provides structure and binds the base; swap with almond flour for a gluten-free alternative.
- Brown Sugar – Brings moisture and sweetness; light brown sugar works beautifully as a substitute.
- Salt – Essential to enhance the flavors; always include for balanced sweetness.
- Cold Butter – Creates a crumbly texture in the base; unsalted is preferred for better control over saltiness.
For the Chocolate Filling
- Evaporated Milk – Adds creaminess to the chocolate layer; can be swapped with sweetened condensed milk for a richer taste.
- Heavy Cream – Enriches the filling and adds richness; half-and-half can be used for a lighter option.
- Corn Syrup – Ensures sweetness and gives the filling a beautiful glossy finish.
- Granulated Sugar – Adds sweetness to the chocolate filling.
- Unsweetened Chocolate – The heart of the chocolate layer; dark chocolate can elevate the flavor for those who crave extra richness.

Step‑by‑Step Instructions for Bonfire Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). Prepare a baking dish (around 9×13 inches) by greasing it with cooking spray or lining it with parchment paper for easy removal later. Setting the right temperature is crucial for achieving the perfect texture in your Bonfire Bars, ensuring they bake evenly and have that delightful crunch on the crust.
Step 2: Make the Graham Cracker Crust
In a large bowl, combine graham cracker crumbs, flour, brown sugar, and salt. Mix these dry ingredients well before using your fingertips or a pastry cutter to incorporate the cold, cubed butter until the mixture resembles coarse crumbs. Evenly press the crumbly mixture into the bottom of your prepared baking dish. It should be firm and slightly golden at the edges after baking.
Step 3: Prepare the Chocolate Filling
In a medium saucepan over medium heat, combine evaporated milk, heavy cream, granulated sugar, corn syrup, and the remaining cubed butter. Stir until the mixture is smooth and begins to simmer—this should take about 5 minutes. Remove the pan from the heat and stir in the unsweetened chocolate until completely melted and the mixture looks glossy. Pour this luscious chocolate filling over the crust layer and let it set slightly while you move to the next step.
Step 4: Bloom the Gelatin
In a small bowl, sprinkle gelatin over cold water to bloom it for about 5 minutes. Meanwhile, in a saucepan, combine sugar, corn syrup, honey, and water, heating it over medium-high until it reaches the soft ball stage (240°F). Once ready, pour this sugar syrup over the bloomed gelatin and whisk vigorously until the mixture becomes thick and fluffy—this should take about 5-6 minutes.
Step 5: Spread the Marshmallow Topping
Gently spread the fluffy marshmallow mixture over the chocolate layer using a spatula, ensuring an even distribution. This topping will add that nostalgic marshmallow flavor reminiscent of s’mores and give your Bonfire Bars a delightful texture. Once spread, place the baking dish in the fridge and chill for at least 1-2 hours, or until the topping is set and firm.
Step 6: Slice and Serve
Once chilled and set, remove the Bonfire Bars from the fridge. Using a sharp knife, slice into squares or rectangles, cleaning the knife with a damp cloth between cuts for neat edges. These bars will have layers of chewy chocolate and fluffy marshmallow, embodying the essence of s’mores. Serve them at room temperature and watch as they become a crowd favorite!

Make Ahead Options
These Bonfire Bars are fantastic for meal prep enthusiasts looking to save time during busy weeks! You can prepare the graham cracker crust up to 24 hours in advance by pressing it into the baking dish and storing it, covered, in the refrigerator. The chocolate filling can also be made a day ahead; simply refrigerate it in an airtight container after allowing it to cool. When you’re ready to serve, spread the marshmallow topping over the chilled chocolate and allow it to set for at least 1-2 hours before slicing. This way, you’ll maintain that fluffy texture while enjoying the same delicious flavors!
Expert Tips for Bonfire Bars
• Quality Ingredients: Using high-quality chocolate and fresh ingredients makes a noticeable difference in flavor, enhancing your Bonfire Bars.

• Experiment with Toppings: Don’t hesitate to add your favorite nuts, sea salt, or even crushed candy bars on top for added texture and flavor.
• Avoid Overbaking: Check your bars towards the end of baking; they should remain soft in the middle for the perfect chewy texture.
