Making a Coffee Mousse is not only super easy, it also requires a few ingredients only. Coffee of course, but also Cream and Eggs to create the mousse texture.
I chose to add more ingredients like Cacao Powder because chocolate and coffee work so well together, but these Espresso Mousse could easily be made with 5 Ingredients only.
Here are all the ingredients that I used to make this Easy Coffee Mousse (scroll down to recipe card for all quantities)
- Heavy Cream (Thickened Cream)
- Caster Sugar
- Instant Coffee Powder or Espresso Powder
- Gelatine Powder and Water (you can also use Gelatine Leaves – see note on the recipe card)
To finish the Mousses
- Unsweetened Cacao Powder
- Espresso Powder
These are optional but a great way to finish the dessert. You can use one or the other – or mix them together before sifting them over the cups like I did!
How to make a Mousse with Coffee
There are a few easy steps to make this Coffee Mousse Recipe: whisk the Egg Yolks with Caster Sugar, heat up the cream with the Coffee Powder, re-hydrate the Gelatine and whip the Egg Whites.
It may sound like a lot of steps but do not worry, it is much easier than it seems!
- Seperate the Egg Yolks and Whites. Place the Egg yolks in a heat-proof bowl and the Whites in the bowl of your Mixer.
- Re-hydrate your Gelatine Powder (or leaves) with some Water – make sure to follow the instructions on your gelatine package regarding the quantity of water needed.
- Place the Heavy Cream, Instant Coffee Powder and Unsweetened Cacao Powder in a small pot and heat it up on low heat until fully dissolved.
- Whisk the Egg Yolks and Caster Sugar, then pour the warm Cream over it while whisking. Transfer the whole preparation back in the pot and whisk on low heat until it starts to thicken.
- Transfer into a clean heat-proof bowl and mix in the re-hydrated Gelatine. Set aside to cool down completely.
- Whip the Egg Whites until you reach stiff peaks. When the cream has cooled down, fold in the Egg Whites.
- Leave in the fridge to set for at least two hours.
Note: Like explained in my Raspberry Mousse Recipe, this mousse is made with Raw Egg Whites that are whipped. It is absolutely fine to eat raw eggs as long as they are fresh, but if you would prefer to cook the egg whites, you can make an Italian Meringue instead of a French Meringue.
An Italian Meringue is made by pouring a hot sugar syrup over the egg whites while they are being whipped. The heat of the syrup cooks the eggs. You can read more about making Italian Meringue here.
How to store this dessert
The French Coffee Mousse need to be kept in the fridge as they contain Cream and raw Eggs.
How long will this Mousse last
They can be made ahead and store in the fridge for 2 to 3 days, but are best eaten fresh within 24 hours.
Can I freeze them?
I do not recommend freezing these mousse cups as they will loose their fluffy texture when thawed.
How to serve this Coffee Dessert
These Coffee-Flavoured Mousses are a great dessert as they are and do not need extra toppings or sauce.
That being said, there are many food items that can be added to these light and creamy Mousses to make the dessert even more decadent!
I simply topped my Espresso Mousses with a little bit of super thin Espresso Powder and Unsweetened Cacao Powder, but you could also finish the dessert with:
- Chocolate Ganache or Chocolate Sauce
- a Raspberry Coulis or Strawberry Coulis to contrast the coffee flavour
- simple Whipped Cream
- a small scoop of Vanilla Ice Cream

- Add the re-hydrated Gelatine to the cream and whisk well until completely integrated. Set aside to cool down fully.
- While the cream is cooling down, start whipping the Egg Whites to get stiff peaks.
- When the cream is cool, gently fold in the Whipped Egg Whites in 3 to 4 times. Try not to overwork the cream.
- Pour the Coffee Mousse into individual cups or jars and place in the fridge to set for at least 2 hours.
- Optional: when ready to serve, sprinkle some Instant Coffee Powder and Cacao Powder over the mousses to finish them.
- You can substitute 1 teaspoon of Gelatine Powder with 1 Gelatine Sheet. Follow the instructions on the package for the quantity of water needed to re-hydrate the gelatine sheet, and make sure you drain it well before adding it to the cream.
