When I made the vegan entremet cake a few weeks ago, I needed only a slice of the gluten free chocolate sponge cake. Knowing I’d have plenty of leftovers, I used them for this mouthwatering vegan chocolate mousse cake.

To use trimmings or leftover vegan chocolate sponge cake as crumbs, cut the sponge into small pieces and dry them in a 120°C (248°F) oven for at least an hour. Pulse or crush them as you do with graham crackers.

Unlike any other chocolate mousse cake, this vegan triple mousse cake recipe has no added sugar, a gluten free crumb base, and no gelatin or eggs added. Preparing the mousse is as simple as folding whipped cream into the melted chocolate.

How To Assemble The Vegan Chocolate Mousse Cake

  • Prepare the crumb base. Pulse the dried gluten-free, vegan chocolate sponge cake into fine crumbs in a food processor. Press the crumbs evenly into the bottom of the cake ring to form a dense, even layer.
  • Dark chocolate mousse layer. Spread the dark chocolate mousse over the cake base with a piping bag and refrigerate for 10 minutes to set.
  • Milk Chocolate mousse layer. Repeat the process used for dark chocolate mousse, then refrigerate to set.
  • White chocolate mousse layer. Lastly, fill the cake ring with the white chocolate mousse, then freeze for at least an hour to set.
  • Assembly on dessert glass. Follow the same steps for layering the mousses. Watch the video for the technique and decorations.

Key Ingredients And Substitutes

  • Chocolate crumb – although the recipe uses leftover chocolate sponge cake, any gluten free, vegan chocolate cracker or graham works fine.
  • Vegan chocolates — professional brands like Felchlin and Valrhona are among the best chocolates for baking, but the substitutes mentioned below are equally good. 
  • Vegan whipping cream – the recipe uses Surewhip, but Califia Heavy Whip Dream works well, too.

  • Refrigerate the base to set while preparing the mousse layers.
STEP 2 – Make the Vegan Dark Chocolate Mousse
  • Melt the vegan dark chocolate with the heavy cream on a double boiler. Fold the whipped cream into the warm melted chocolate until smooth.
  • Pour over the set cake crumb base and refrigerate until the mousse is firm.
STEP 3 – Add the Vegan Milk Chocolate Mousse Layer
  • Repeat the process used for the dark chocolate mousse, using vegan milk chocolate this time.
  • Once the dark chocolate layer sets, carefully pipe the milk chocolate mousse on top.
  • Return to the refrigerator to set.
STEP 4 – Finish with the Vegan White Chocolate Mousse
  • Melt the vegan white chocolate with the heavy cream. Fold the whipped cream into the melted white chocolate until well combined.
  • After the milk chocolate layer has set, pipe the white chocolate mousse on top.
  • Freeze or refrigerate the cake until completely firm, ideally overnight.
