This is a dessert that I can eat on a regular basis, but for obvious reasons I don’t. The great thing about chocolate mousse is that you can make it according to your taste, by choosing the chocolate you prefer. You can go crazy by picking a 90% chocolate bar and end up with a very bitter, almost mouth twisting mousse. On the other hand, a semi-sweet or even a milk chocolate or a combination will render a much sweeter end result.
Key Ingredients in This Recipe

You’ll find the complete list of ingredients and exact quantities in the recipe below.
- Dark chocolate – I like very dark chocolate, so for when I make this dessert for me and my husband, “I pick my poison”, my chocolate, in the high numbers, 70-90%. Less dark or a combination of dark and milk chocolate will also work.
- Butter
- Instant espresso coffee powder – this will enhance the chocolate flavor
- Egg whites
- Egg yolk
- Sugar
- Whipping cream
How to Make Ultimate Chocolate Mousse

Step 1 – Cut the chocolate in small pieces, add a little bit of warm water and melt it.
The fastest and easiest way to melt chocolate is in the microwave. Heat in small intervals on 30-40% of max. If you prefer to do it au-bain-marie, please do so.
Once the chocolate is melted, add the instant coffee powder and the butter and mix this until smooth. Set aside to cool a little.
Step 2 – Mix the egg yolk with the sugar and whip until white and creamy.
In separate bowls, whip the egg whites and whipping cream stiff and place the bowls in the fridge.


Step 3 – Add the slightly cooled chocolate to the egg yolk-sugar mixture and combine.
Step 4 – Add part of the egg white to the chocolate mixture and then add the chocolate mixture to the rest of the egg whites. Mix.


Step 5 – Add the whipped cream and fold it into the mix. You don’t want to end up with white areas, but you also don’t want to mix the air out of the mousse.
You worked hard to get a lot of air in this mixture and all that air will create a wonderful, fluffy and light (not caloric light, but light in feeling) mousse.
- Step 6 – Divide over 2 dessert bowls or ramekins and refrigerate at least 2 hours.
You can also keep it in the mixing bowl, place it in the fridge and when it is time to serve, scoop it out of that bowl in fancy serving dishes. This way you can actually see the beautiful mousse. Decorate with raspberries, strawberries, or mint.

Instructions
- Cut the chocolate in small pieces, add 2 tablespoons of warm water and melt it. (NOTE 3)

- Add the slightly cooled chocolate to the egg yolk-sugar mixture.
- Add part of the egg white to the chocolate mixture and then add the chocolate mixture to the rest of the egg whites.
- Add the whipped cream and mix well, but tenderly. You don't want to end up with white areas, but you also don't want to mix the air out of the mousse.
- Divide over 2 dessert bowls and refrigerate at least 2 hours.
- Decorate with fruit or mint or both.
Notes
- If you prefer a lighter chocolate, a mix of dark and milk chocolate will work equally well.
- It is not easy to divide an egg white, due to the gel-like structure. There are 2 ways to get 1/2 egg white
- Whip the egg white until you break the gel-like structure and then pour half off.,
- Use liquid egg white. 1 large egg white = 2 tablespoons of liquid egg white. For this recipe you’ll need 1.5 egg whites, that translates into 1 egg (you will also use the egg yolk) and 2 tablespoon of liquid egg white.
- Melting chocolate can be done in a microwave or au-bain-marie.
