When it comes to S'mores, more is better! So I had to make JUMBO-size S'more Brownies. These are amazing AND messy to eat, the way a campfire S'more should be. Jumbo S'mores Brownies are easy to make if you use a box brownie mix.
Prep Time 30minutes
Cook Time 1hour10minutes
Total Time 1hour40minutes
218 ounce boxes/pouches Triple Chocolate Ghirardelli brownie mix ( plus eggs, water and canola oil for mix)
1 ¾cupgraham cracker crumbs
1stick½ cup butter, just melted (not bubbling)
Make the graham cracker crust
Preheat the oven to 350 degrees. Line a 9 X 13 baking with parchment paper, leaving enough overhand to create handles. This is important to make lifting the completed S’more Brownies out of the pan at the end. Combine the graham cracker crumbs, sugar and melted butter in a medium size bowl. Gently mix with a fork to create a wet crumb mixture. Transfer the crumb mixture to the prepared baking dish. Using the bottom of a water glass or kitchen mallet, press the crumb mixture firmly into the bottom of the dish. Bake the crumb crust at 350° F for 12 - 14 minutes. Remove from oven and let cool for 15 minutes. Turn the oven down to 325 degrees.
Make the brownie layer
In a large bowl with a hand mixer, miix 2 pouches of brownie box mix according to directions on the package. The Ghirardelli Triple Chocolate Brownie Mix required 2 eggs plus canola oil and water. Transfer the brownie batter to the baking pan, evenly covering the graham cracker crust. Bake the brownies for 50 -55 minutes at 325 degrees or until the center comes out clean when tested with a cake tester. Remove from oven. Leave oven on at 325 degrees.
Make the marshmallow layer
While the brownies are still warm, line 24 jumbo-size marshmallows on top of the brownie layer. Place the pan back in the oven for 5 minutes or until the marshmallows are soft and puffed up. Turn on the broiler, and broil the tops until toasted and golden brown. It is critical to monitor this step closely so they do not burn! Immediately remove the pan from the oven.
Slice the Brownies
Allow the S’more Brownies to cool for at least an hour.Using the handles of the parchment, lift the brownie slab out of the pan and place on a cutting board. Using a large serrated knife, cut the brownies into 24 bars. The marshmallow layer will be very sticky. Run the knife under very hot tap water after each cut to make it easier.Store in an airtight container.
