Ingredients & Notes

See the recipe card for full information on ingredients and quantities.

​There are only five components to make this chocolate coffee mousse, with dark chocolate as one of the base ingredients—let's have a look.

• Dark chocolate: Pick good quality chocolate with high levels of cacao—anywhere from 70 to 80%. Go for 56% instead, If you are a sweet chocolate lover.
• Egg whites: The recipe calls for egg whites at room temperature, which means remove the eggs from the fridge and let them sit on the kitchen counter for about 30 minutes before using them— it helps beat egg whites properly to stiff peaks. You can use carton egg whites versus shelled.
• Maple syrup: One tablespoon is more than enough to add that touch of extra sweetness and caramelized undertones.
• Brewed Coffee: Pick your favorite coffee bean to make a strong black coffee. Half a cup will give you a decent coffee flavor, but you can tone it down to about three tablespoons for a slight hint of it. You can also use homemade cold-brew coffee.
• Berries: You can use fresh or frozen. Although only used for garnish, I find them a must to take this chocolate and coffee dessert to the next level.

Note: You don't need any gelatin, heavy cream, or any other thickeners. It's an egg white chocolate mousse only.

How To Make It

See the recipe card for full information on ingredients and quantities.

Maybe it is one of the fastest coffee chocolate mousse you'll ever make. But for ten minutes, it does require your undivided attention.

Step One (Picture 1 above) - Melt chocolate in a small saucepan over low heat. Stir in the maple syrup and the coffee. Remove from heat and reserve.

Step Two (Picture 2 above) - In a bowl of the stand mixer or food processor, beat your egg whites until stiff, meaning until peaks stand straight up when you lift your beater from the mixture (about 5 minutes on medium speed).

Step Three (Picture 3 above): When the white foam is ready, add the chocolate coffee mixture in increments.

Step Four (Picture 4 above) - Gently fold small amounts of the chocolate mixture into the beaten egg whites with a spatula. It will give the foam the proper time to temper and adjust to the chocolate base.

Step Five (Picture 5 above) - Gently blend everything until you get a uniform and beautiful brown mixture with a creamy texture.

Step Six (Picture 6 above) - Divide mousse equally into small cups of your choice for individual servings. Chill in the refrigerator for at least 30 minutes or let sit overnight to get a beautiful mousse texture. 

When ready to serve, garnish with berries and extra chocolate shavings.

Helpful Tips 

• Melting the chocolate: Continuously stir while melting the chocolate because it can burn quickly. You have to stay with it to get that smooth, glowy paste infused with coffee and maple syrup. There is no need to cool the mixture completely. Instead, let it sit off the stove while tending the egg whites.
• Creating stiff peaks: It is super easy when using a stand mixer or electric whisk. However, I have whisked it by hand before—in case you want to test your arm strength, go for it. The key to a stable white foam with beautiful peaks is to use either a glass or large metal bowl and wipe it thoroughly clean first. Trust me, any dust, wet, or fatty particles in it will prevent the egg whites from stiffening.
• Folding in the chocolate: Use a whisk or rubber spatula and go gently. Don't overmix here, and work fast yet smoothly because you don't want the foam to deflate too much (it is the only aerator in this recipe giving this mouse its airy texture). Going gently will also give the foam the proper time to temper and adjust to the chocolate base. Always fold in by hand to get a uniform and beautiful brown mix—never use an electric mixer at this stage.
• Chilling: Ensure that you portion the mousse into your desired serving cups as soon as it is made and before it's set and chilled. It will be runny enough to do so. Use a spoon or a pastry bag to simplify things (not necessary). Then place it in the fridge to chill.

Substitutions and Dietary Alternatives

• Switch up the flavors: Choose a bar of flavored chocolate. Almond, hazelnut, vanilla, and mint-flavored chocolate work well with coffee.
• Keep it dairy-free and low-carb or keto-friendly: Choose a chocolate brand that uses cocoa butter and no added sugar—I'm suggesting some of my favorites in the recipe notes. Also, replace maple syrup with a maple syrup alternative (see recipe notes).
• Love vanilla or a hazelnut-flavored cup of Joe? Go ahead—it works great in this coffee mousse recipe!
