I have been meaning to share this recipe for a while and what better time than now.

After all, Valentine’s Day is just around the corner. And nothing better than chocolate to celebrate it right?

If you love all things chocolate, then you have to try this Eggless Chocolate Mousse Cake.

It has a base layer made of chocolate cake, topped with the mousse and finally finished with a ganache.

So that’s 3 layers of chocolate goodness!

This cake is super easy to put together, don’t get intimidated by the three layers. It is all pretty simple.

Let’s break down this into 3 parts and talk about each in detail.

Chocolate Cake: so the base is a chocolate cake.

I have used the same recipe that I used for my eggless chocolate cake and just halved the recipe for this one.

Since I only wanted this cake as a base, it didn’t make sense to use the full recipe so cutting it in half worked better.

The recipe calls for basic ingredients and results in a moist, soft chocolate cake.

It is my no-fail recipe and I hope you guys give this recipe a try.

My recommendation is to use a good quality cocoa powder, my preference is Anthony’s Cocoa.

Chocolate Mousse: this eggless chocolate mousse is super simple and requires only a handful of ingredients.

It is very important to use a good quality chocolate here. Also a mix of semi-sweet and dark chocolate gives good flavors and that’s what I have used here.

To make the mousse, you only need to melt the chocolate and then fold in the whipped cream.

Super simple right?

Chocolate Ganache: now you may skip making the ganache but if you love chocolate as much as I do, then just go for it!

I used dark chocolate for the ganache here but you may use semi-sweet as well.

To make the ganache, you just need to heat the cream and then add it to the chopped chocolate and then stir until everything comes together.

Remember, you don’t have to boil the cream but heat it well and then add to the chopped chocolate.

The chocolate should be chopped fine, if it’s chopped into bigger pieces then it might not melt as quickly.

And now let’s talk about the size of the cake pan.

For this eggless chocolate mousse cake recipe, I used a 9-inch springform pan.

However, I later felt that I should have used a 7 or 8 inch pan. That would have made the cake look taller.

The mousse and ganache had a thin layer because the cake pan was big. If you want taller layers, use a smaller pan.

If you use a 7 inch pan, you will have to adjust the baking time too. You will have to increase the baking time a little, since the smaller pans will be deeper (less surface area).

Hope you guys give this recipe a try, it is really easy and makes a wonderful simple dessert! 🙂

 

Method

Chocolate Cake

Pre-heat oven to 350 F degrees. Lightly grease a 9-inch springform pan with oil spray and set aside.

1- In a large bowl sift together flour, cocoa powder, baking soda and salt. Set aside.

2- To a measuring jar or bowl, add 1/2 tablespoon white vinegar to 1/2 cup milk and set it aside for 5 to 10 minutes. This milk will curdle a little, and this is your buttermilk to be used in the recipe.

You can straight away also use 1/2 cup store bought buttermilk in place.

3- To the milk now add the granulated sugar and mix well until the sugar dissolves.

4- Add the oil and mix.

5- And then add the vanilla extract and mix.

6- Now, add the wet ingredients to the dry ingredients (the flour-cocoa powder mix)

7- Mix until everything is combined but do not over-mix. Few streaks of flour is fine.

9- Pour prepared batter into a lightly greased 9 inch springform pan. Use a spatula to spread the batter in the pan.

9- Bake at 350 F degrees for 18-20 minutes. Mine was done at 18 minutes. Remove cake from oven and let it cool completely.

Chocolate Mousse

10- Take chopped chocolate in a bowl (I used mix of semi-sweet and dark) and add butter to it. Put this bowl on top of a pot of simmering water (not boiling). And the bowl should not touch the surface of the water. This is called double-boiler method.

11- Melt the chocolate using the double boiler method. You can also use a microwave here. Let the melted chocolate cool down to room temperature, this is important so don’t rush this step.

12- Meanwhile, whip the cream until it forms stiff peaks using the wire whisk attachment of your stand mixer (or use a hand mixer). I also add a splash of vanilla while whipping the cream but that’s optional.

Make sure to chill the steel bowl and wire whisk attachment for 15-20 minutes before whipping the cream for best results. Of course, the cream needs to be chilled too.

13- Once, the melted chocolate has cooled down to room temperature, start adding the whipped cream to it in parts. Add 1/4th of the whipped cream first.

14- Then mix using the cut and fold method, moving your spatula in one direction. Do not mix very vigorously else you will deflate all the air from the whipped cream, so fold gently.

15- Similarly, fold in the entire cream until you have a smooth mousse.

16- Transfer the prepared mousse on top of the baked cake. Make sure your cake is cooled completely before you put the mousse on top (this is important).

17- Spread the mousse on top of the cake using an offset spatula. Chill the cake in the refrigerator for minimum of 2 to 3 hours.

Chocolate Ganache

18- Once the cake has chilled, make the ganache. Place chopped chocolate in a bowl.

Heat the cream in a pan on medium-low heat. It should just come to a simmer. Add the heated cream to the bowl of chopped chocolate. Let it sit for 1 minute.

19- Start whisking the chocolate with the milk, until it all melts into a smooth ganache.

20- Pour the prepared ganache on top of the chilled cake. Refrigerate again for 1 hour.

To serve the eggless chocolate mousse cake, sprinkle cocoa powder on top and then cut into slices and serve.

I would suggest taking the cake out of the fridge and letting it sit for around 20 minutes before serving, the mousse tastes better that way :)!

  1. Isnt it similar to chocolate whipped cream? No offense here i am just trying to understand how is it different from chocolate whipped cream!
    Thank you :).

    1. you can add some gelatin or agar agar flakes if you want it firmer. This works fine for me and that’s why I shared it 🙂

  2. 5 stars
    Thanks For Sharing this amazing recipe. My family loved it. I will be sharing this recipe with my friends. Hope the will like it.

    1. sorry recipe not tested with self raising flour, and self raising flour replacement works okay if recipe has baking powder, but this has baking soda so it might not work

  3. 5 stars
    Hi Manali, My cake is not rising well enough. In this cake’s ingredients there is no baking powder. Don’t we need baking powder?

  4. Hi, any substitute for unsaltes butter? Like maybe some oil or mixture of salted butter & oil? Also instead of chocolate bar, would cocoa powder give similar result?

  5. You have mentioned unsalted butter under the chocolate mousse ingredients..but in the method there is no mention of when we have to add the butter..do we add it while melting the chocolate??…also can I make white chocolate mousse using the same measurements?

    1. I can see it mentioned “Take chopped chocolate in a bowl (I used mix of semi-sweet and dark) and add butter to it.”
      I haven’t tried white chocolate mousse with this recipe but you can try.

  6. What if the convection’s max temp is 250deg only.. Could i still follow this recipe for the cake?

    1. the temperature mentioned is in fahrenheit (I live in the US). It calls for 350 F which is 180 C for your oven.

  7. 5 stars
    This really turned out lovely. I added a bit of a bite by spreading some raspberry jam over the cake and scattering some chopped toasted macadamia nuts over the jam before putting up the mousse layer and finishing off with the ganache topping. Thank you very much for this recipe. ??

      1. Thanks, also do you think if I use two 6 X 2 inch pans, this recipe will work out ? I am thinking of layering this up and making a tall cake.

      2. It turned out really good Manali. Your recipes are always full proof. 🙂 Now I am planning to use three 6 X 2 inch pans to make the cake taller and use 1.5 times of the ingredient list.

  8. Hello Manali:

    I made this several times and we love it. I noticed that because its eggless, it turns a bit dry by day 2 or 3. If I want to make this cake with eggs, how many would I use.

    1. Hi Mona, 1 egg should be okay here. But if you are adding egg, it will be better to use a different recipe and not this one. This has been tested without eggs only, and since baking is a science different ingredients react differently so I am not sure if the result will be the same. And if you wrap your cake tightly using a cling sheet and then place it an airtight container, it will not become dry.
