I had this recipe in mind for quite a bit now and I finally came to make it. Vegan chocolate mousse cake! When it comes to vegan mousse recipes, people would go like “How on earth do you make chocolate mousse without dairy or eggs?”. But the thing is there are plenty of plant-based ingredients that make delicious chocolate mousse!
The first recipe I came across for chocolate mousse before I was into vegan baking used coconut cream as the base. And while I loved the taste of it, the texture was quite dense and I wanted something more moussey, airy and fluffy. So I explored some inspiration and decided to incorporate aquafaba to make the mousse nice and fluffy! Honestly, I’m so happy with the texture. It’s so rich, thanks to the coconut cream, and yet fluffy and airy thanks to aquafaba!
This recipe needs no baking so it’s beginner-friendly and easy to make too. Such a lovely chocolaty treat that will be loved by all chocolate lovers and everyone else!
This recipe is:
- can be gluten-free
- no added sugar
- can be refined sugar free
Main ingredients and substitutions
Almond: almond is one of the ingredients for the raw chocolate brownie base. I like using almond in my recipe as they give a lovely fragrance and texture to baked goods or no-baked goods in this case! If you want to avoid nuts, you can make this recipe nut-free by swapping almonds with oats or seeds.
Dates: I used Medjool dates in moth the base and mousse to sweeten them naturally! Dates are such an amazing natural sweetener with vitamins and minerals to sweeten baked goods(or no-baked goods!). I like using Medjool dates as they are the juiciest of all dates I have tried, but if you can’t find them you can use other types of dates too.
Cacao powder: Cacao powder is used to give a nice chocolate flavour to the base and mousse. Don’t use cocoa powder here! Cocoa powder contains sugar and other things in it already so it would alter the taste of the final product. You can also use carob powder if you like.
Aquafaba: Wondering what aquafaba is? Aquafaba is a leftover juice from when you cook chickpeas! When I first heard about it, I was sceptical. But it actually does make nice vegan meringue when whipped with an electric mixer. I use aquafaba when I want to make pancakes super fluffy but this time it helped me achieve the rich and airy texture that I was looking for in the mousse!
Coconut milk: I used the fat part of canned coconut milk that separates on top for the base of the mousse. The cream is rich in fat so it creates an amazingly rich texture. If you want to sub, you can use tofu instead too, it makes it low-fat high protein chocolate mousse but still tastes great!
Vegan milk chocolate: I added vegan milk chocolate to the mousse to make it extra rich and chocolaty. If you want to make this recipe completely refined sugar free, choose the one that has no added sugar.
Maple syrup: I added some maple syrup to sweeten up a tad more. You can use other syrups too such as agave syrup, date syrup, etc.
Soy cream: I used some soy single cream to make a ganache top.
Recommended equipment for this recipe
Cake tin: I used my 18cm(7inch) cake tin for this recipe. You can use a circle or square tin, whatever shape as long as the size is the same.
Parchment paper: It makes it a lot easier to remove the cake from the tin if you line it beforehand. Simply cut a piece of parchment paper the size of the bottom and side of the tin, spread a thin layer of oil or vegan butter then line inside.
How to make this vegan chocolate mousse cake
Step 1: Make the base
The first thing to do is make the base! It’s super simple. Add all the ingredients for the raw chocolate brownie base into the food processor and blitz until it makes a firm dough. Transfer the mixture to a cake tin and press it down to the bottom firmly using your fingers or the bottom of a drinking glass. Set the base in the fridge while making the mousse!
Step 2: Make the vegan chocolate mousse cake filling
To make the chocolate mousse layer is very simple too! First, melt the vegan milk chocolate and pre-soak the dates in hot water until they are softened for about 20 mins. Then put all the ingredients for the mousse except the aquafaba in the food processor and blend until smooth and creamy. Set aside.
In a large bowl, beat the aquafaba until it’s fluffy and makes a peak, about 8-10 mins with an electric hand mixer or stand mixer. Add the chocolate mixture to the aquafaba and mix on low speed until they are just combined. Don’t over mix! If you do the mixture will deflate and won’t be fluffy.
Pour the mousse over the raw chocolate brownie base. Smooth the top evenly and set it in the fridge for 6 hours or overnight. You can also speed up the process by placing it in the freezer for 3-4 hours.
Step 3: Make the chocolate ganache top
To make the ganache top, simply mix the vegan milk chocolate and soy cream until smooth. Once the cake is set, spread the ganache on top evenly and decorate the cake with strawberries, blueberries, and some shaved chocolates. Slice and enjoy!
Tips and tricks
Mix the chocolate mixture and aquafaba gently
Be careful not to beat too much when you are mixing the two mixtures. Aquafaba can deflate if you mix it with the chocolate mixture too vigorously at high speed. Once you have done beating aquafaba, turn the speed down to the lowest and mix them as quickly and gently as you can.
Use fresh and juicy dates
Use fresh and juicy dates! Avoid using old, dry ones as they can make the base crumbly and not tasty. If the dates you are using is fresh but not as juicy as Medjool dates, soak them in hot water for 15-20 mins until they are softer then follow the instruction.
Warm up the knife before cutting
The ganache top can be a little harder than the mousse layer. While I love the combination of the slight crunch of the ganache and airy mousse cake, it might be a little difficult to cut into it. If this happens, warm up the cake knife on a stovetop then carefully cut the cake.
How to store this chocolate mousse cake
You can store this cake in the fridge for up to 2 days. Put them in a cake container or slice them then put them in an airtight container to keep it nice and fresh. The cake can also be stored in the freezer. Simply put it in a freezer friendly airtight container and store in the freezer for up to 2-3 months.
Q and A
Can I use something else other than coconut milk?
I’m sure you can use tofu instead of coconut milk. The texture should be very similar but it might be less rich because of the less fat content.
