Chocolate Almond Mousse Cake

April 10, 2026 By Gretchen

Jump to Recipe Jump to Video Print Recipe

Bakery copy cat recipe for Chocolate Almond Mousse Cake!

So sophisticated you are going to get rave reviews I guarantee it!

Chocolate Almond Mousse Cake

 

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

Chocolate Mousse Cake ~ Almond Sponge Cake

 

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 

Combining vegan butter and oil results in the best textured cake but you can use all of one or the other if you prefer

Cream of Tartar is used to strengthen meringues but it is not an essential ingredient.
Nor is the agar addition since chocolate mousse is the most stable mousse without added stabilizers

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

Additionally I have changed the mix method from the tedious creaming method to an easier one bowl mix
Flax meal was in the original recipe but I have since eliminated it since the added fat component was slightly too heavy here 

Convert easily to 2-8″ cake layers with no changes to the recipes.

  • 1 teaspoon Baking Powder
  • 1 teaspoon Baking Soda
  • ½ teaspoon Salt
  • 1 cup Raw Almonds 150g

For the Chocolate Mousse

  • 8 ounces Semi Sweet Vegan Chocolate 226g
  • 3 Tbs Hot brewed coffee 45ml
  • 1 teaspoon Vanilla Extract 5ml
  • ¼ cup Aquafaba 60ml
  • 4 Tbs Granulated Sugar 50g
  • ¼ teaspoon Cream Of Tartar
  • 1½ cups Vegan Whipped Cream

For the Amaretto Chocolate Ganache

  • 4 ounces Semi Sweet Vegan Chocolate 113g
  • 6 Tbs Plant Milk 90ml
  • 2 Tbs Amaretto 30ml

For the Simple Syrup

  • ½ cup water
  • ½ cup sugar
  • 2 Tbs Amaretto *optional

For the Icing

  • 1 Recipe Swiss Meringue Buttercream
  • 2 teaspoon Almond Extract

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
  • 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 combine the melted vegan butter, oil, plant milk, extracts & sugar
  • Sift the flour with the salt, baking powder & baking soda then add it to the wet ingredients in the bowl & whisk to a smooth batter
  • Add the finely ground almonds & mix evenly
  • Portion the batter into your prepared pans & bake in the preheated 350°F oven for 15minutes. 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
  • Whip the aquafaba with the cream of tartar to stiff peaks while adding the sugar very slowly~ reserve
  • 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

    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?
