S’mores Fudge Bars Ingredients

For the Graham Cracker Crust

Graham Crackers – The perfect base for the crust; digestive biscuits or Biscoff cookies can be a tasty substitute.
Granulated Sugar – Adds sweetness to the crust; for a rich flavor shift, use brown sugar instead.
Fine Sea Salt – Balances out the sweetness; table salt works in a pinch—just avoid coarse varieties.
Unsalted Butter – Binds the crust and infuses richness; make sure it’s melted for easy mixing!

For the Fudgy Chocolate Filling

Semisweet Chocolate Chips – Yields the ultimate fudgy goodness; dark chocolate chips offer a deeper intensity.
Sweetened Condensed Milk – Unites the chocolate layer with creaminess; a pouch can save time for busy days.

For the Marshmallow Topping

Egg Whites – Essential for a light, fluffy topping; they provide structure that makes all the difference.
Cream of Tartar – Stabilizes egg whites when beaten; feel free to leave it out if you’re in a hurry.
Corn Syrup – Creates a smooth texture in the marshmallow; golden syrup can substitute nicely, though honey may change the flavor.
Water – Helps dissolve sugar in the syrup mixture for a foolproof marshmallow.
Vanilla Extract – Enhances the overall flavor; if you’re looking to switch it up, almond extract is a lovely alternative.

Step‑by‑Step Instructions for S’mores Fudge Bars

Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). Take an 8×8-inch baking pan and line it with foil, leaving some overhang for easy removal later. This will ensure your S’mores Fudge Bars come out easily and helps with cleanup. Set the prepared pan aside while you make the crust.

Step 2: Make the Graham Cracker Crust
In a food processor, combine graham crackers, granulated sugar, and fine sea salt. Pulse until the mixture resembles fine crumbs. Next, pour in the melted unsalted butter and pulse until everything is evenly moistened. Press this mixture firmly into the bottom of your prepared pan, creating a solid layer. Bake the crust in the preheated oven for 10 minutes until it’s just golden.

Step 3: Prepare the Fudgy Chocolate Filling
While the crust cools, combine semisweet chocolate chips and sweetened condensed milk in a saucepan over medium-low heat. Stir continuously until the chocolate is completely melted and the mixture becomes thick and smooth—about 5-7 minutes. Once done, pour the luscious chocolate filling over the cooled graham cracker crust and spread it evenly. Transfer back to the refrigerator to set while you make the marshmallow topping.

Step 4: Whip Up the Marshmallow Topping
In a stand mixer or a large bowl, beat egg whites and cream of tartar on medium speed until soft peaks form, around 3 minutes. Meanwhile, in a separate saucepan, combine sugar, corn syrup, water, and a pinch of salt. Bring to a boil over medium heat, stirring until the sugar dissolves, then cook until it reaches 240°F (115°C) using a candy thermometer. Slowly drizzle the hot syrup into the whipped egg whites while beating at high speed until thick and glossy, about 5-7 minutes.

Step 5: Assemble and Toast the Bars
Spread the marshmallow topping over the chocolate layer in the pan, smoothing it out with a spatula. For a toasted finish, use a kitchen torch to carefully toast the marshmallow until it’s golden brown and bubbly, about 1-2 minutes. Alternatively, you can broil the bars on low for just a few seconds, but watch closely to prevent burning.

Step 6: Chill and Serve
Refrigerate the assembled S’mores Fudge Bars for at least 1 hour, allowing the marshmallow to set. Once chilled, lift the bars out of the pan using the foil overhang and cut them into squares. Serve these delightful treats at your next gathering or enjoy them as a special sweet indulgence at home!

Tips for the Best S’mores Fudge Bars

Crust Consistency: Ensure the graham cracker crust is firmly packed. A loose crust will crumble when you cut into the bars, so press it down well before baking.

Marshmallow Perfection: Beat egg whites until soft peaks form. This creates a fluffy marshmallow topping. Using a stand mixer ensures even beating to avoid scrambling.

Watch the Heat: When broiling the marshmallow, keep a close eye to prevent burning. The heat can be deceptive; a few seconds can turn perfect to charred.

Chill Time Count: Don’t skip the refrigeration step. Allowing the S’mores Fudge Bars to set for at least an hour helps everything meld together and makes cutting easier.

Flavor Variations: Get creative! Try using different types of chocolate or add a swirl of peanut butter to the fudgy layer for a delightful twist.

Simply follow the initial steps of your recipe, then cover the cooled crust with plastic wrap and refrigerate it after adding the chocolate layer. To maintain the quality of the marshmallow topping, it’s best to whip that up fresh right before serving or up to 3 hours ahead. After toasting the marshmallow layer, let the bars set in the fridge until you’re ready to cut and serve, ensuring they are just as delicious and enjoyable for your friends and family!

S’mores Fudge Bars Recipe FAQs

How do I know if my graham crackers are fresh enough?
Absolutely! Use graham crackers that are free from any dark spots or signs of mold. If they feel soft or have an off smell, it’s best to ditch them for a fresh pack. A crunchy texture is key for the crust, ensuring a delightful contrast to the gooey filling.

What’s the best way to store leftover S’mores Fudge Bars?
Very! Store your fudgy bars in an airtight container in the fridge for up to 5 days. They’ll retain their delicious freshness and gooey texture. If you notice they start to dry out, consider wrapping them in plastic wrap before placing them in the container to lock in moisture.

Can I freeze S’mores Fudge Bars? How?
Yes, you can freeze them! Wrap each bar individually in plastic wrap, followed by aluminum foil, to prevent freezer burn. Place them in a freezer-safe container or bag, and they can be frozen for up to one month. When you’re ready to enjoy, simply thaw them overnight in the fridge for the best results.

What should I do if my marshmallow topping doesn’t whip up properly?
If your marshmallow topping isn’t getting fluffy, it could be due to not beating the egg whites long enough or using an inadequate bowl. Make sure your mixing bowl is clean and grease-free. Try beating until soft peaks form, and ensure your sugar syrup reaches 240°F—this helps achieve a stable, glossy peak when added to the egg whites.

Are there any allergy considerations with this recipe?
Certainly! This recipe contains eggs, dairy, and may contain gluten, making it unsuitable for those with allergies to these ingredients. If you’re cooking for someone with dietary restrictions, consider using gluten-free graham crackers and a dairy-free chocolate option. Always check labels to ensure ingredients meet dietary needs.

Can I use store-bought marshmallow fluff instead of making my own?
Absolutely! If you’re in a hurry or want to simplify the process, store-bought marshmallow fluff can be a fantastic substitute. Simply spread it over the chocolate layer before toasting for that beloved s’mores taste without the extra step.
