The secret to this Oven-Baked S’mores Recipe lies in simple, wholesome ingredients that work beautifully together. Each one plays a role in creating the perfect balance of sweetness, crunch, and ooey-gooey texture that makes this dish irresistible.

½ cup unsalted butter: Adds rich creaminess and helps bind the crust together for that perfect buttery base.

2/3 cup packed light brown sugar: Offers a deep caramel flavor that complements the marshmallows perfectly.
½ cup 2% milk: Provides moisture and richness to the graham cracker paste, making it smooth and spreadable.
1 teaspoon vanilla extract: Enhances the overall sweetness with a warm, familiar aroma.

1¼ cups graham cracker crumb: Brings the classic s’mores crunch and a slightly nutty flavor.
350 g whole graham crackers: The essential dry base that forms the layers separating the mix of chocolate and marshmallows.
2½ cups milk or semisweet chocolate chips or chunks: Melts beautifully to create luscious pockets of chocolate yum.

6 cups mini marshmallows: Toasted to golden perfection, they create that signature gooey and fluffy topping that everyone loves.

How to Make Oven-Baked S’mores Recipe

Step 1: Prepare Your Pan and Preheat the Oven

Start by setting your oven to 350°F. Line an 8 or 9-inch square pan with parchment paper, making sure the paper extends above the pan edges. This thoughtful step will make lifting the bars out easier later.

Step 2: Make the Gooey Graham Cracker Paste

In a saucepan over medium-low heat, melt the butter. Stir in the brown sugar, milk, and vanilla extract, warming it just enough to take the chill off the milk. Remove from heat and whisk in the graham cracker crumbs until you get a fluid, indulgent paste that’s ready to spread.

Step 3: Layer the Magic

Place a single layer of whole graham crackers on the bottom of your prepared pan. Spoon a third of your graham cracker paste over the crackers—not worrying about full coverage—and spread it around gently. Sprinkle one-third of your mini marshmallows and chocolate chips on top. Then, repeat this layered love two more times: graham crackers, paste, marshmallows, and chocolate chips.

Step 4: Bake to Gooey Perfection

Pop your pan into the oven for 16 to 20 minutes until the marshmallows are beautifully browned. This is where the magic happens—the marshmallows puff up, turning golden and tantalizingly toasted, while the chocolate melts into luscious pools.

Step 5: Cool and Portion

After baking, let the pan cool on a wire rack. If you’re not serving immediately, chill it completely to firm up the s’mores for clean, easy squares. Once chilled, slice into portions and get ready to dig in!

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Store any leftover slices in an airtight container at room temperature for up to three days. This keeps them soft and gooey without drying out, so you can enjoy guilt-free seconds whenever the craving strikes.

Freezing

If you want to savor this Oven-Baked S’mores Recipe over a longer period, wrap portions tightly in plastic wrap and place them in a freezer-safe container. They freeze well for up to one month and thaw quickly when you’re ready.

Reheating

To bring back that freshly-baked feel, warm your chilled or frozen s’mores squares in a low oven or microwave for just 15 to 20 seconds. This melts the chocolate gently without burning the marshmallows, reviving all the lovely textures and flavors.

Description

Delicious oven-baked s’mores featuring layers of graham crackers, a rich buttery brown sugar mixture, gooey mini marshmallows, and melty chocolate chips, baked to golden perfection and perfect for sharing.

Ingredients

Brown Sugar Butter Mixture

½ cup unsalted butter, cut into pieces
2/3 cup packed light brown sugar
½ cup 2% milk
1 teaspoon vanilla extract
1¼ cups graham cracker crumbs

S’mores Layers

350 g whole graham crackers (approximately 32–48 crackers, depending on the brand)

6 cups mini marshmallows

Cook Mode Prevent your screen from going dark

Instructions

Preheat Oven: Set your oven to 350°F (175°C). Line an 8 or 9-inch square baking pan with parchment paper, making sure the paper extends about an inch above the sides to facilitate easy removal later.
Make Butter Mixture: In a saucepan over medium-low heat, melt the butter. Whisk in the light brown sugar, milk, and vanilla extract. Heat gently just for about a minute to warm the milk and dissolve the sugar, then remove from heat.

Incorporate Graham Cracker Crumbs: Immediately whisk the graham cracker crumbs into the warm butter mixture until you get a smooth, fluid paste. This acts as the ‘goo’ layer to bind everything together.
Assemble First Layer: Arrange a single, even layer of whole graham crackers to completely cover the bottom of your prepared pan. Spoon one-third of the graham cracker paste over this layer, spreading it somewhat (it doesn’t need to fully cover the crackers). Sprinkle one-third of the mini marshmallows evenly on top, followed by one-third of the chocolate chips.
Repeat Layers: Place another layer of whole graham crackers over the marshmallow and chocolate layer. Repeat the process of spreading a third of the paste, then marshmallows, then chocolate chips. Repeat once more for the final layer, layering the remaining graham crackers, goo, marshmallows, and chocolate.

Bake: Place the pan in the preheated oven and bake for 16-20 minutes until the marshmallows are golden brown and toasted on top.
Cool and Serve: If you’re not serving immediately, let the pan cool on a wire rack, then chill completely to firm up. Slice into squares once chilled for clean portions. Serve immediately or store at room temperature for up to 3 days.

Notes

Using parchment paper that extends above the pan sides helps lift the s’mores out easily for easier slicing.

For a gooier center, reduce baking time slightly; for crunchier marshmallows, bake longer but watch carefully to avoid burning.
You can substitute semisweet chocolate chips or half milk and half semisweet for a balanced sweetness.
Chilling before cutting results in neater squares and easier handling.
