Stepwise Method: Smores Chocolate Mousse Bars.

Step 1: Prepare the Crust
Begin by preheating your oven to 350°F (175°C). In a mixing bowl, combine the finely crushed graham cracker sheets and melted salted butter. Stir until the mixture resembles wet sand. Press it firmly into the bottom of a greased 9×9 inch baking pan. Bake for 10 minutes, then remove and let it cool while you prepare the mousse.
Step 2: Make the Chocolate Mixture
In a double boiler or microwave-safe bowl, melt the 6 ounces of milk chocolate until smooth. Add the finely chopped 8 ounces of semi-sweet or dark chocolate to the melted milk chocolate and stir until melted and combined. Allow this mixture to cool slightly.
Step 3: Prepare the Mousse Base
In a separate bowl, whisk together the egg yolks, 2 teaspoons of vanilla extract, and a pinch of flaky sea salt. Gradually whisk in the melted chocolate mixture until fully combined.
Step 4: Whip the Cream
In a large mixing bowl, beat the heavy cream until soft peaks form. Gently fold about one-third of the whipped cream into the chocolate mixture to lighten it. Then, fold in the remaining whipped cream until fully combined.
Step 5: Whip the Egg Whites
In another clean bowl, whip the 4 egg whites until soft peaks form. Gradually add in the granulated sugar, continuing to whip until stiff peaks form. Gently fold the egg whites into the chocolate mousse mixture, being careful not to deflate the air you’ve incorporated.
Step 6: Assemble the Bars
Pour the chocolate mousse over the cooled graham cracker crust, spreading it evenly. Cover and refrigerate for at least 4 hours, or until set.
Step 7: Serve and Enjoy
Once set, cut the bars into squares and serve chilled. You can garnish them with additional whipped cream or a drizzle of chocolate sauce if desired.
Vegan & Vegetarian Swaps

If you’re looking for vegan or vegetarian alternatives, consider these swaps:
- Graham crackers – Use vegan graham crackers to keep the crust plant-based.
- Butter – Substitute with coconut oil or vegan butter.
- Eggs – Use aquafaba (the liquid from canned chickpeas) as an egg white replacement.
- Heavy cream – Use full-fat coconut milk or a vegan whipping cream alternative.
Insider Tips
- Make sure all your ingredients are at room temperature for the best results.
- For a more intense chocolate flavor, use a higher percentage of dark chocolate.
- Be patient while folding in the whipped cream and egg whites; this preserves the light and airy texture.
- For an added touch, roast some mini marshmallows and place them on top before serving for that classic smores experience.
