S’mores Brownies

This recipe is from an old article in Cook’s Country magazine which included several variations on brownies. This version is baked over a graham cracker crumb crust and topped with a layer of broiled marshmallows. They’re rich and fudgy, but If you line the pan and chill for a while before cutting, you’ll find that they are less gooey than they sound.

Marshmallow topped brownies with a graham cracker crust
Recipe type: Dessert
Serves: 9
  • 3/4 cup graham cracker crumbs
  • 1 tablespoon sugar
  • 4 tablespoons melted butter
  • 3 ounces unsweetened chocolate
  • 1/2 cup unsalted butter (4 ounces)
  • 2 large eggs
  • 1 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 1/2 teaspoon baking powder
  • 2/3 cup all purpose flour
  • 2 cups (approximately) marshmallows
  1. Preheat the oven to 350 degrees F. Line an 8 inch square metal pan with nonstick foil.
  2. Mix the graham cracker crumbs with the sugar and melted butter. Press into bottom of lined pan and bake for 8 minutes.
  3. Prepare brownies. Melt the chocolate and butter together in the microwave, a double boiler or heavy saucepan. Set aside to cool for about 5 minutes. Meanwhile, whisk the eggs and sugar until light. Whisk in the vanilla, then whisk in the salt and baking powder. Add the melted chocolate to the egg mixture and stir until mixed. Add flour and stir until mixed. Do not overbeat, just stir until it’s absorbed. Pour the brownie mixture over the graham crust. Return to oven and bake for 22-26 minutes or until set.
  4. Remove from oven and sprinkle marshmallows over top in one generous layer. Set oven’s broiler heat to high and return pan to oven. Broil for 1 minute or until golden. Keep a close eye, because marshmallows brown quickly!
  5. Let cool on a rack. When cool, chill. Lift from pan and cut into 9 big squares.
  6. Makes 9 large brownies

    These brownies sound like something that would be great fun to make with a child and even more fun to share!

    Thinking of New Year’s and cookies, have you ever made champagne cookies? I don’t have any recipes, but I know they exist. I wonder if they’re good? I love Champagne!! What a good excuse to pop the top on a bottle!!

    Sue, I’ve never heard of champagne cookies but I’m interested! If you find a good recipe, let me know. I’ll be on the lookout myself. Another thing (kind of unrelated) is Chardonnay Cake. I’ve seen a few recipes for it and wonder how it tastes.

    Hi Anonymous, and thanks. Yes, these are a bit like Mallomars or S’mores.

    I never remember which is Petco and which is PetSsmart either. (But one of them smells..)

    I’ve got some graham crackers that I want to be rid of, so I think I’ll try these! I’m a bit of a s’mores nut.

    I’ve been reading for awhile, but I finally had to comment! I’m so glad to hear you have housekeepers. I could never figure out how you had time for all your mom/wife “jobs”, plus bake every day and maintain your blog. Thank you, I feel less inadequate! Love your blog by the way.

    Hey Anna, these sound really good! I found a box of graham cracker crumbs in my cupboard, but they have an expiration date of July 07 on them! Do graham cracker crumbs go bad??? Wasn’t sure if they can be weevily or not…

    Hi Michelle,

    I would toss the graham cracker crumbs and buy new ones. Even if there are no bugs, they will surely taste stale.

    Yum, I love S’mores. Can’t wait to give this a try. Initially I was look for your s’mores cookies and struck gold with these.

    Just made these tonight for company and my husband really enjoyed them. I didn’t think that the topping/crust added much (I think I’d rather have the brownie plain), but will definitely try them again because they were a hit, and they certainly don’t detract from the brownie either.
