All of my vegan mousse recipes are based off of the traditional non-vegan method for making mousse
Incorporating aquafaba instead of the egg white meringue
With agar as the stabilizer instead of gelatin you are back in business with making all sorts of mousse concoctions that you probably thought were gone forever!
This raspberry mousse cake idea came from my recipe for Pumpkin Mousse Cake.
That recipe took off like a rocket and sparked so much conversation in all the social media groups that I am in.
Someone asked if the pumpkin puree could be substituted with another puree like raspberry.
The answer to that was yes!
But not without some slight changes because pumpkin is a thicker puree and has some natural thickening properties in and of itself.
Raspberry puree, while it does have some natural pectin in the fruit, it is a much thinner puree.
So I had to adjust the agar in the aquafaba slightly to help this whole thing set up.
I also used whole raw raspberries rather than cooking them down to a puree.
And added vegan white chocolate as a binder to help it all set up for slicing.
The cashews are the base for a cold preparation mousse like this and totally necessary to aid in the setting of the whole thing.
I know I will get some questions right away if you can swap out those nuts for something else.
And yes you can make a mousse without them but not this recipe.
That would require an entirely different recipe formulation.
The same goes for pretty much every ingredient here, this recipe has been formulated to work out perfectly.
So I wouldn’t recommend trying to substitute out anything here.
It just isn’t going to work out I’m afraid
If you watch the full video tutorial on YouTube for how to make this cake, you will see that he thin chocolate cake layers are hidden inside the mousse.
I liked that effect since when it is un-molded you will just see the stunning raspberry mousse and nothing else.
The chocolate ganache drip is of course the moment we all wait for so be sure to watch the video even if you don’t plan to make this cake!
That upside down ganache drip is mesmerizing!
If you decide to go for one of those instead of the chocolate cake, just halve the recipe and bake it into 1-8″ Pan
- For the Mousse:
- Raw Cashews Soaked 2 cup (300g) * I soak my nuts in bulk then measure
- Fresh Raspberries 2 cup (454g)
- Cocoa Butter or Coconut Oil ½ cup (113g)
- Coconut Milk ½ cup (120ml)
- Vegan White Chocolate 6 ounces
- Confectioner's Sugar 1½ cup (180g)
- Raspberry Jam *optional 1 Tablespoon (15ml)
- Aquafaba liquid from a can of chick peas ½ cup (120ml)
- Agar ¾ teaspoon
- You will also need:
- ½ Recipe Chocolate Cake
- ¼ Recipe Vegan Ganache
- First prepare your cake recipe as per the recipe instructions (bake into 1-8" cake pan) and while it is cooling you can prepare the raspberry mousse as follows:
- First prepare the stabilized aquafaba by heating it over low heat with the ½ teaspoon of the agar powder and bring it to a boil.
- Cool to tepid (not cold or the agar will thicken the liquid before we can whip it) then you can prepare the rest of the recipe
- Heat the coconut milk with the other ¼ teaspoon of agar and bring it to a boil (be sure to keep this warm or the agar will set the milk- if that happens though, just rewarm it to dissolve again)
- Combine the soaked cashews, raspberries, jam, confectioner's sugar the warm agar-coconut milk, melted cocoa butter or coconut oil and melted white chocolate in a high speed blender of food processor and blend smooth on high for about 45 seconds to 1 minute or until there are not traces of cashews in the mixture
- Transfer to a large mixing bowl
- Whip the cooled (or room temperature) agar-aquafaba with a balloon whip attachment to stiff glossy peaks and then fold into the raspberry mixture
- Pour half of the mousse into the prepared mold, then slice your cake layer into 2 layers and trim it slightly smaller in diameter than the actual ring mold (this is so the cake will not show through the sides after unmolding)
- One layer goes into the center and then the rest of the mousse on top.
- *Optional to add more fresh raspberries to each layer as I did in the video
- The other cake layer goes on top, press down firmly so the mousse will come up around the sides (as shown in the video) and refrigerate until set at least 5 hours or overnight.
- Prepare the ganache recipe according to the instructions on that post/recipe and then unmold the cake and ice with cooled but still pourable ganache as shown in the video
You can also freeze for longer storage up to 1 month
