Bakery copy cat recipe for Chocolate Almond Mousse Cake!
So sophisticated you are going to get rave reviews I guarantee it!

Unlike most vegan cakes which can border on gummy if you are not careful
This chocolate almond mousse cake does great with a soaking of Amaretto Simple Syrup!
However you can leave that out altogether if you are alcohol free

Neither the almond sponge cake nor the mousse are very sweet
So the buttercream icing is the perfect balance to this winning combination.

Notes for Success:
My preferred method of building cakes with soft fillings like this one is to use a ring mold with an acetate cake strip *see video
Alternatively you can fill the cake traditional style with a buttercream dam as usual
The best results for this cake texture came from grinding raw almonds to a course meal
Rather than using nut flour that I purchased at the store
Store bought nut flour is too fine and resulted in a slightly more dry and heavy cake
Cream of Tartar is used to strengthen meringues but it is not an essential ingredient.
Yogurt was used in the original recipe as you will see in the video
But I have since eliminated that additional ingredient and use more plant milk instead
Convert easily to 2-8″ cake layers with no changes to the recipes.

Instructions
- For the Almond Cake Batter Be sure all your ingredients are at room temperature before beginning.
- First prepare your 7" cake pans with grease & parchment paper lining & preheat the oven to 350°F
- Combine the flax meal & hot water together in a small bowl & set aside to thicken for about 5 minutes.
- Grind the almonds in a food processor or chop as fine as possible by hand
- Sift the flour with the salt, baking powder & baking soda
- In a large mixing bowl, cream the vegan butter& sugar on medium to high speed until light & fluffy, this may take close to 5 minutes. Scrape the bottom & sides of the bowl from time to time to ensure an even mix.
- Add the flax paste to the creamed mixture & then whip on high for 10 seconds to emulsify
- Turn the speed back down to low and add 1/3 of the sifted dry ingredients & mix just until it is combined
- Now add half of the plant milk with the extracts & mix just until combined
- Repeat with another 1/3 of the dry ingredients, the other half of the plant milk & then the last of the dry ingredients. (this is called alternating creaming method)
- Now add the finely ground almonds to the batter & mix evenly
- Portion the batter into your prepared pans & bake in the preheated 350°F oven for 20 minutes. Then turn the oven temperature down to 300° & bake for another approx 20 minutes or when a toothpick inserted into the center comes out clean
- Cool the cakes in the pans until they are cool to the touch, then flip them out onto a wire rack to cool the rest of the way.
- Prepare the buttercream recipe of your choice and set it aside
- Prepare the Chocolate Ganache by chopping the chocolate to small pieces & place in a medium sauce pot with the plant milk whisking constantly over medium heat until melted & smooth. Add the Amaretto *If alcohol free you will use more plant milk
- The truffles are simply scoops of cooled & set ganache rolled into chopped almonds~ Optional garnish
- For the Chocolate Mousse Melt the chocolate in a large bowl over a double boiler or in a microwave safe bowl~ Reserve
- Combine the hot coffee & the agar powder in a smaller sauce pot over high heat & whisk smooth. Keep it warm or the agar will set and you will have to remelt.
- Meanwhile whip your favorite whipped cream to medium peaks & reserve in the refrigerator
- Now whip the aquafaba with the cream of tartar to stiff peaks while adding the sugar very slowly~ reserve
- Now prepare the mousse: Add the hot brewed coffee with the agar & the vanilla extract to the melted chocolate all at once while whisking vigorously to incorporate well.
- Add half of the whipped cream to the COOLED chocolate mousse base (must be at least 80℉ or you will melt your whipped cream) mix well to lighten the mixture- work quickly as the agar will begin to set~ then add the rest of the whipped cream
- Finally fold in the whipped aquafaba meringue
- At this point you can allow the mousse to set in the refrigerator to a scoop-able consistency to build the cake, or set the cake up in a ring mold & pour the freshly made mousse into the mold with the cake layers so everything can set together firmly *see video visual
- Once the mousse is set inside the cake, proceed to assemble & ice the cake as shown in the video tutorial

Notes
Store bought nut flour is too fine and resulted in a slightly more dry and heavy cake Cream of Tartar is used to strengthen meringues but it is not an essential ingredient. Convert easily to 2-8" cake layers with no changes to the recipes. Storage Chocolate Mousse Cake must be kept refrigerated but can be kept at room temperature for an hour during serving. Store for up to 1 week in the refrigerator wrapped loosely to prevent drying

If I’m using the aquafaba from your life hack with the Agar in it, how does that change this recipe for the chocolate mousse? With the coffee and Agar separate, etc.
Thanks!!
What is the simple syrup for? I don’t see it being used in the recipe, nor in the Youtube video O.o Are the cakes supposed to be brushed with it once they’re cooled?
I’m excited to try this recipe! Thanks 🙂
Hey thanks for pointing that out! I feel like I may have mentioned in the video that I was not using simple syrup? But should have? Or would have??
I can’t quite remember, but I will make a note of that here to reflect the simple syrup is completely optional!
You would just brush a bit onto the cake layers while building the cake
Hi! Is there a way to scale this up for 3, 8” cake pans?
Yes sure, I would probably do 1½X the recipe for everything
