Ingredients for Classic S’mores Bars

Main Ingredients

1 ½ cups graham cracker crumbs (or crushed full sheets)
½ cup unsalted butter, melted
2 cups chocolate (milk, semi-sweet, or dark)
2 cups marshmallows or mini marshmallows
1 tablespoon vanilla extract
Pinch of salt

Optional Ingredients

Mini chocolate chips for extra chocolatey goodness
Chopped nuts like almonds or walnuts
Caramel drizzle or sea salt for added flavor
Flavored marshmallows (e.g., strawberry or caramel) for a twist

Ingredient Notes

Graham crackers: Using crumbs creates a firm, even crust, while full sheets give a rustic look.
Chocolate: High-quality chocolate melts better and enhances the flavor.
Marshmallows: Mini marshmallows work best for even melting, but regular marshmallows can be chopped into pieces.

How to Make Classic S’mores Bars

Step 1 – Preparing the Crust

Preheat your oven to 350°F (175°C).
Combine graham cracker crumbs, melted butter, and a pinch of salt in a bowl.
Press the mixture firmly into the bottom of a greased or parchment-lined 9×13-inch baking pan.
Bake for 5–7 minutes to set the crust lightly.

This step ensures a sturdy, crisp base that won’t become soggy when you add the chocolate and marshmallows.

Step 2 – Adding the Chocolate Layer

Spread chocolate evenly over the baked graham cracker crust.
Sprinkle mini chocolate chips on top if desired for extra texture.

Even layering of chocolate helps every bite have a balanced flavor with the crust and marshmallow.

Step 3 – Layering the Marshmallows

Arrange marshmallows evenly over the chocolate layer.
For a gooier top, you can slightly melt marshmallows in the microwave before layering.

This layer is the heart of the s’mores bars, giving that iconic melty, fluffy texture.

Step 4 – Baking the Bars

Bake at 350°F (175°C) for 10–15 minutes, until marshmallows are golden and puffed.
Optional: Broil for 1–2 minutes for a lightly toasted top.

Keep a close eye during broiling to prevent marshmallows from burning.

Step 5 – Cooling and Serving

Allow the bars to cool for at least 10 minutes to set slightly.
Cut into squares with a sharp knife.
Serve warm for gooey goodness, or let cool for firmer bars that are easier to handle.
