Ingredients for S’mores Chocolate Mousse
- Chocolate Mousse:
- 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)
- Marshmallow Topping:
- 4 large egg whites
- 1 cup (200g) granulated sugar
- 1/2 teaspoon cream of tartar
- 1/2 teaspoon pure vanilla extract
Step-by-Step Instructions
- Make the mousse: Whisk egg yolks, sugar, and salt in a heat-proof bowl. Set aside.
- Bring 3/4 cup (180ml) heavy cream to a simmer in a saucepan over medium heat. Reduce heat to low once simmering.
- Temper the egg yolks: Whisking constantly, pour 1/4 cup of warm cream into the egg yolk mixture. Combine, then pour back into the saucepan. Cook, whisking constantly, until thickened (about 3 minutes or 160°F).
- Remove from heat, stir in vanilla, and set aside.
- Melt chocolate in a double boiler or microwave (20-second increments, stirring until smooth). Stir melted chocolate into the egg yolk mixture.
- Whip the remaining 1 1/4 cups (300ml) heavy cream to medium peaks (3-4 minutes). Gently fold into the chocolate mixture. Avoid over-mixing.
- Layer graham cracker crumbs and mousse in 6-ounce glasses: 1 Tbsp crumbs, 1/3 cup mousse, 1 Tbsp crumbs, 1/3 cup mousse. Repeat for 5 more parfaits.
- Chill for at least 3 hours (up to 1 day). Cover if chilling longer than 3 hours.
- Make the marshmallow topping: Combine egg whites, sugar, and cream of tartar in a heatproof bowl. Place over simmering water (double boiler works). Whisk constantly until sugar dissolves and mixture thins (about 4 minutes).
- Remove from heat, add vanilla, and beat on high until stiff glossy peaks form (5 minutes).
- Spoon or pipe marshmallow cream onto chilled mousse cups. Serve immediately or refrigerate uncovered for 1-2 hours. Toast with a kitchen torch if desired.
- Store leftovers covered in the fridge for up to 1 day.
Perfect Pairings: Serving Suggestions
Elevate your S’mores Chocolate Mousse by serving it with a side of fresh berries like strawberries or raspberries for a refreshing contrast. For an extra indulgent touch, drizzle a bit of caramel or chocolate sauce over the top. Pair it with a cup of coffee or a glass of dessert wine to complete the experience.
Storage Secrets: Keeping It Fresh
Store your mousse parfaits in the refrigerator, covered with plastic wrap or aluminum foil, for up to 1 day. If you’ve added the marshmallow topping, it’s best to enjoy them within 1-2 hours for optimal texture. For longer storage, keep the mousse and marshmallow separate and assemble just before serving.
Time-Saving Tips: Streamline Your Prep
To save time, prepare the graham cracker crumbs and melt the chocolate ahead of time. You can also whip the heavy cream in advance and store it in the fridge until you’re ready to fold it into the chocolate mixture. This way, you can focus on assembling the parfaits without feeling rushed.
Recipe Variations: Mix It Up
For a twist, try using dark chocolate instead of semi-sweet for a richer flavor. You can also swap out the graham cracker crumbs for crushed cookies like Oreos or digestive biscuits. If you’re feeling adventurous, add a layer of peanut butter or Nutella between the mousse and crumbs for an extra layer of decadence.
Equipment Essentials: Tools You’ll Need
Make sure you have a heat-proof bowl for tempering the egg yolks and a double boiler or microwave-safe bowl for melting the chocolate. A hand mixer or stand mixer with a whisk attachment is essential for whipping the cream and marshmallow topping. For a polished look, use a piping tip like Ateco 808 for the marshmallow cream.
S’mores Chocolate Mousse
Ingredients
Chocolate Mousse
- 4 large egg yolks
- 1/4 cup granulated sugar (50g)
- 1/8 teaspoon salt
- 2 cups heavy cream (480ml), divided
- 1 teaspoon pure vanilla extract
- two 4 ounce semi-sweet chocolate bars (226g), finely chopped*
- 1 cup graham cracker crumbs (100g) (about 8 graham crackers)
Marshmallow Topping
- 4 large egg whites
- 1 cup granulated sugar (200g)
- 1/2 teaspoon cream of tartar
- 1/2 teaspoon pure vanilla extract
Instructions
- 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.
