Here are notes about some of the ingredients needed to make these s'mores bars recipe. All ingredients can be found at your local grocery store or at an online retailer, like Amazon.
- Graham crackers - I always use the honey flavored graham crackers. You will need about 1 ½ sleeves of graham crackers turned into crumbs.
- Butter: Use unsalted melted butter in the graham cracker crust.
- Semisweet chocolate: You can use a semisweet chocolate bar or chocolate chips. I prefer a bar for a smoother chocolate filling. Choosing a high quality chocolate will give you the best results.
- Heavy whipping cream
- Egg whites: You can use egg whites that you separate from eggs yourself or store-bought egg whites in a carton will work just as well.
- Vanilla extract
- Cream of tartar
Step by Step Instructions
Here is how to make these easy s'mores bars. For the full ingredient list and recipe instructions, see the recipe card below.
Prepare the Graham Cracker Layer
STEP 1: Preheat oven to 350°F. Spray a 9-inch square baking pan with cooking spray.
STEP 2: In a small bowl, combine the graham cracker crumbs, sugar and butter. Stir well to combine.
STEP 3: Transfer the mixture to the prepared baking pan and press the mixture into the bottom using your hands, making sure to get to the edges and corners.
STEP 4: Bake in the preheated oven for 8-10 minutes or unitl the crust is set. Remove from the oven and allow to cool while you prepare the fudge layer.
Prepare Fudge Layer
STEP 1: Place chocolate in a medium sized bowl.
STEP 2: Heat whipping cream in a small saucepan over medium heat just until boiling.
STEP 3: Pour the whipping cream over the chocolate and allow it to sit for 10 minutes before stirring.
STEP 4: Stir the chocolate mixture well until fully combined.
STEP 5: Pour the chocolate mixture over the graham cracker crust. Cover with plastic wrap and place in the refrigerator for at least 1 hour and until completely set.
Prepare the Marshmallow Layer
STEP 1: In the bowl of an electric mixer, add the egg whites, vanilla, cream of tartar, and salt. Beat on high speed until soft peaks form.
STEP 2: Combine the sugar and water in a saucepan and bring to a boil over medium-high heat. Cook, without stirring, until a candy thermometer registers 250°F.
STEP 3: With your mixer running on a medium-low speed, you pour the hot sugar mixture in a thin stream over the egg whites. Switch to high speed and beat until stiff peaks form.
STEP 4: Spread the marshmallow topping over the top of the fudge. There is plenty of marshmallow, so use as much as you would like and save the extras for another treat! You can use the back of a spoon or a spatula to create little peaks in the marshmallow or spread it smooth.
STEP 5: Place on middle rack under the broiler for 1 ½ to 2 minutes. Watch closely and rotate as needed. Remove when it's golden brown and toasted to your liking!
STEP 6: Sprinkle the tops with additional graham cracker crumbs.
- To make graham crackers crumbs. Place graham crackers in the bowl of a food processer and process until fine crumbs form. To get 1 ¼ cups of graham cracker crumbs, you will need about 1 ½ sleeves of graham crackers.
- If you would like to be able to pull the bars out to cut them, make an aluminum foil sling for the pan. To do this, cut two strips of aluminium foil that are slightly longer than the pan. Allow the edges to hang over the sides of the pan. This makes it easy to lift the bars out ounce they are done. Do not use parchment paper because you will be placing the bars under the broiler and the paper could ignite.
- To get the graham cracker mixture even in the bottom of the pan, use the bottom of a measring cup to press the mixture down.
- Before you begin the marshmallow topping, make sure the bowl of your mixer and whisk attachment are free of any residual oil. If you don't you will have trouble getting your egg whites to whip up correctly.
- Place marshmallow topping in a piping bag fitted with a large tip and pipe the topping on in a decorative pattern, if desired!
Yes. Semisweet chocolate chips work for the fudge center. You could use your preferred strength of chocolate if you like a darker chocolate flavor. Adjust to your liking!
Absolutely! I feel like I need supervision when using the kitchen torch, so I like to use the broil method if no one is around to make sure I don't burn the house down. The torch allows for a more controlled toast on the top of your pie though, so if you have one, and you aren't scared like me, use it!
Sure. A graham cracker crust and a fudge layer would be delicoius too! Sprinkle the tops with graham cracker crumbs for a deocorative touch!
