S’mores chocolate mousse combines fluffy mousse with graham crackers and homemade marshmallow cream. Learn how to make homemade chocolate mousse using this tutorial and whip out your kitchen torch for an unbelievable finish to a fun parfait-style dessert.
Fingers crossed you love s’mores and all the delicious flavors the campfire treat brings.
Crackling fire or not, I love serving this nostalgic dessert in many different forms. With desserts like no-bake s’mores cake, s’mores brownie cupcakes, and s’mores chocolate mousse, we can all agree that s’mores-ifying desserts is never going out of style.
National S’mores Day is August 10th, so I’m using this celebration as an excuse to show you how to make real chocolate mousse. We’ll layer the homemade chocolate mousse with graham cracker crumbs and top the whole parfait with homemade marshmallow cream, aka creamy sweet meringue. We’re toasting that marshmallow, too. ♥
If there’s ever been a good excuse to own a kitchen torch, s’mores chocolate mousse is it!
Let’s Make Chocolate Mousse
Have you ever made chocolate mousse before? If not, let me teach you. While the ingredient list is pretty basic, there’s a few steps requiring your attention. Helpful preliminary information: you need 2 cups of heavy cream total. Use some in the beginning, then the rest towards the end.
- Whisk: 4 egg yolks, sugar, and a pinch of salt together. We’ll use the leftover egg whites in the marshmallow topping.
- Simmer: 3/4 cup heavy cream on the stove.
- Temper: While constantly whisking, pour 1/4 cup warm cream into the egg yolks, then pour the egg yolk mixture into the remaining warm cream.
- Cook: Until thickened.
- Stir: Remove pan from heat, then stir in vanilla extract. Pictured on the left below.
- Melt: Melt two 4-ounce semi-sweet chocolate bars until completely smooth. It’s best to use real baking chocolate, such as Baker’s or Ghirardelli. Finely chop each bar, then melt in the microwave in 20 second increments until smooth.
- Combine: Whisk the melted chocolate and egg yolk mixture.
- Whip: Beat the remaining heavy cream into medium peaks.
- Fold: Gently fold the chocolate mixture into the whipped cream.
Whip the heavy cream, pictured below, then fold in the chocolate mixture. This from-scratch chocolate mousse is like a lighter, fluffier, richer tasting chocolate pudding. It’s fantastic plain or you can serve it with whipped cream and fresh berries. The best way to serve it, as you can guess, is with graham crackers and homemade marshmallow. 🙂
How to Make Marshmallow Cream
I’ve taught you how to make marshmallow cream a few times before: Baked Brownie Alaska, S’mores Brownie Cupcakes, Chocolate Mousse Pie, and Ultimate Birthday Cupcakes. It’s basically Swiss Meringue, but don’t let the word “meringue” frighten you. This is a simple 4 ingredient mixture cooked on the stovetop, then beaten into stiff peaks. It tastes like marshmallow fluff– but better because it’s homemade!
Whisk egg whites, sugar, and cream of tartar together in a double boiler or heat-proof bowl over a small pot of simmering water. Whisk until sugar has dissolved and mixture has thinned out, about 4 minutes. Remove from heat, add vanilla extract, then whip on high speed for 5-6 minutes until stiff glossy peaks form. Whipping is where the magic happens. The mixture will go from thin liquid to as voluminous as the puffiest cloud in the sky. It’s soft, creamy, sweet, and sticky– all the best parts of marshmallow!
(It’s like Swiss Meringue Buttercream, just without the butter.)
What’s the cream of tartar for? Cream of tartar stabilizes the egg whites and helps the meringue hold its stiff peaks. It’s an imperative ingredient.
Assemble the S’mores Chocolate Mousse
The chocolate mousse must chill for at least 3 hours before serving. The chilling stage creates that cold, creamy, mousse-like texture. Therefore, I recommend layering the mousse into custard cups, ramekins, or little jars with the graham cracker crumbs before chilling. Chill in the refrigerator, then make the marshmallow cream and pipe it on top of each layered mousse cup.
I only use my kitchen torch a few times per year, but when I need it, I’m SO thankful I have it. Heck, you can’t make awesome crème brûlée without it! What a difference this tool makes in the flavor and texture of your desserts. Whip it out and toast the marshmallow topping.
You won’t regret it!
Will you just look at this spoonful!!
This fun parfait-style s’mores dessert combines homemade fluffy chocolate mousse, graham crackers, and homemade marshmallow topping.
- 4 large egg yolks
- 1/4 cup (50g) granulated sugar
- 1/8 teaspoon salt
- 2 cups (480ml) heavy cream, divided
- 1 teaspoon pure vanilla extract
- two 4 ounce semi-sweet chocolate bars (226g), finely chopped*
- 1 cup (100g) graham cracker crumbs (about 8 graham crackers)
- 4 large egg whites
- 1 cup (200g) granulated sugar
- 1/2 teaspoon cream of tartar
- 1/2 teaspoon pure vanilla extract
- Make the mousse: Whisk the egg yolks, granulated sugar, and salt together in a heat-proof bowl. (I use a small glass bowl or liquid measuring cup.) Set aside.
- Bring 3/4 cup (180ml) heavy cream to a simmer in a medium saucepan over medium heat. (The remaining heavy cream is used in step 6.) Once simmering, lower the stove’s heat to low.
- Temper the egg yolks: Whisking the egg yolk mixture constantly, pour in 1/4 cup of the warm heavy cream. Whisk together until combined. Now, whisking constantly, pour the egg yolk/cream mixture back into the saucepan. Whisking constantly, cook the mixture until smooth and thickened, about 3 minutes or until it registers 160°F on a candy/oil thermometer. (I usually don’t measure the temperature, but you can if desired.)
- Remove from heat and stir in the vanilla extract. Set aside.
- Melt chopped chocolate in a double boiler or the microwave. If using the microwave: place the chocolate in a medium heat-proof bowl. Melt in 20 second increments in the microwave, stirring after each increment until completely melted and smooth. Stir melted chocolate into the egg yolk mixture. Set aside.
- Using a hand mixer or a stand mixer fitted with a whisk attachment, whip the remaining 1 and 1/4 cups (300ml) heavy cream on medium-high speed until medium peaks form, about 3-4 minutes. Medium peaks are between soft/loose peaks and stiff peaks. Pour in the chocolate/egg yolk mixture and using a spoon or rubber spatula, gently fold together. Avoid over-mixing which can deflate the mousse. Makes 4 cups chocolate mousse.
- Spoon a heaping Tablespoon of graham cracker crumbs into the bottom of a 6-ounce (or larger) glass, custard cup, ramekin, parfait glass, bowl, etc. Spoon 1/3 cup chocolate mousse on top. Spoon another heaping Tablespoon of graham cracker crumbs on top, then another 1/3 cup of chocolate mousse. Repeat with 5 remaining parfaits. Each parfait has 2/3 cup of mousse and 2-3 Tablespoons of graham cracker crumbs.
- Chill for at least 3 hours and up to 1 day. If chilling longer than 3 hours, cover each with plastic wrap or aluminum foil.
- Make the marshmallow: Place egg whites, sugar, and cream of tartar in a heatproof bowl. Set bowl over a saucepan filled with two inches of simmering water. Do not let it touch the water. (You can use a double boiler if you have one.) Whisk constantly until sugar is dissolved and mixture has thinned out, about 4 minutes. Remove from heat. Add the vanilla extract, then using a handheld or stand mixer fitted with a whisk attachment, beat on high speed for 5 minutes until stiff glossy peaks form.
- Spoon marshmallow cream on top of each chilled mousse cup. If desired, use a large piping tip instead. I used Ateco round piping tip 808. Serve immediately or store in the refrigerator, uncovered for 1-2 hours. If desired, toast the marshmallow topping with a kitchen torch just before serving.
- Cover and store leftover mousse cups in the refrigerator for up to 1 day.
- Make Ahead Instructions: You can assemble the mousse cups with the graham cracker crumbs up to 1 day in advance. (Step 8.) The graham cracker crumbs may become soggy after that. You can add the marshmallow topping up to 1-2 hours before serving. For best taste and texture, I recommend toasting the marshmallow cream immediately before serving.
- Use any 6 ounce or 8 ounce glasses, parfait glasses, custard cups, ramekin, bowls, etc. Recipe serves about 6 generous portions. Feel free to divide between smaller cups for a higher yield. Recipe can be doubled.
- Chocolate: For the best looking and tasting mousse, use two 4 ounce “baking chocolate” bars found in the baking aisle. I prefer Bakers or Ghirardelli brands. You need 2 four ounce bars for this recipe, 8 ounces (226g) total. You can use semi-sweet or bittersweet chocolate. Do not use chocolate chips, as they contain stabilizers preventing them from melting into the proper consistency.
