How to Create a Gooey Top and Fudgy Center in S’mores Brownies
Prepare the Graham Cracker Base
Grab your 9×9 inch pan and line it with parchment paper, letting the edges hang over. This trick makes lifting out the brownies super easy later. Set your oven to 325°F (163°C). In a medium bowl, mix together 1 ¼ cups graham cracker crumbs, 2 tablespoons granulated sugar, and 5 tablespoons melted unsalted butter until everything sticks together nicely. Press this mixture firmly into the bottom of your pan, creating a solid crust. Bake for 8 minutes, then set aside to cool while you tackle the brownie layer.
Create the Chocolate Base
Grab a large bowl and whisk together:
Crack in 3 large eggs and add 1 tablespoon vanilla extract, mixing until the batter looks light and fluffy. Sift in:
Stir just until combined – don’t overmix! Sprinkle in ¾ cup semi-sweet chocolate chips and fold them gently through the batter.
Bake the Brownie Layer
Pour your chocolate batter over the cooled graham cracker crust, spreading it evenly. Slide the pan into the 325°F (163°C) oven and bake for 35-40 minutes. Your brownies are done when a toothpick inserted in the center comes out with just a few moist crumbs. Let the brownies cool completely – patience is key here!
Prepare the Sugar Syrup
In a small saucepan, combine:
Heat the mixture over medium heat, stirring until the sugar dissolves. Stop stirring and let the syrup reach exactly 240°F on a candy thermometer.
Whip the Marshmallow Topping
While the syrup heats, grab your stand mixer. Beat 2 large egg whites and ¼ teaspoon cream of tartar on high speed until soft peaks form. Slowly drizzle the hot syrup into the egg whites while mixing continuously. Keep beating until the mixture becomes stiff and glossy – this takes about 7-10 minutes. Add 1 teaspoon vanilla extract and beat for one more minute.
Finish and Toast
Spread the fluffy marshmallow topping generously over the cooled brownies. If you have a kitchen torch, now’s your chance to create that golden-brown toasted top. No torch? No worries – your broiler can work magic in about 1-2 minutes. Watch carefully to prevent burning. Slice into squares and get ready to enjoy a seriously decadent dessert.

Smores Marshmallow Brownies Question Set For Dessert Lovers
Can I use store-bought marshmallow fluff instead of making my own marshmallow topping?
Homemade marshmallow topping creates a richer texture and flavor. Store-bought fluff won’t give the same glossy, light result and might make your brownies look less professional.
What if I don’t have a candy thermometer for the marshmallow layer?
A candy thermometer ensures precise sugar syrup temperature. Without one, your marshmallow might not set correctly or could become grainy. Investing in an affordable thermometer helps guarantee perfect results.
How do I prevent the graham cracker crust from burning?
Press the crust mixture evenly and bake at the specified temperature. The short 8-minute pre-bake helps set the crust without over-browning. Watch closely and remove when it looks lightly golden.
Can chocolate chips be substituted in the brownie batter?
Definitely! Swap with chunks of dark, milk, or semi-sweet chocolate. Choose high-quality chocolate that melts smoothly for the best brownie texture.
What’s the best way to cut these brownies cleanly?
Use a sharp knife dipped in hot water and wiped dry between each cut. This helps create smooth, clean edges and prevents the marshmallow from sticking to the blade.

- Pour the brownie batter over the cooled graham cracker crust. Spread it carefully to create an even layer.
