Pumpkin Mousse Cake

Yes it’s happening, Pumpkin Everything Season is here!

So to kick it off right, here at Gretchen’s Vegan Bakery, I am coming out of the gate with this amazing new recipe for Pumpkin Mousse Cake.

Pumpkin mousse,  gingerbread cake and a thin coating of chocolate ganache

Pumpkin Mousse Cake

With a just three recipes (Ok, four if you count the pumpkin buttercream!) you too can have this stunning cake at your first fall event.

This elegant cake will wow everyone and when they taste it no one will believe this cake is vegan!

That’s the most beautiful part (for me anyway) is when I get that reaction from people who just can’t believe vegan can taste so good!

This pumpkin mousse is so creamy and light just like an authentic mousse recipe should be.

Whipped aquafaba (stabilized with my newest secret ingredient) this mousse is perfectly stable and it is obviously molded so you can see right away it holds up it’s integrity as an entremet cake.

But for those who just don’t want to go to all the trouble (it’s not really that much trouble! LOL) of making this into a cake, remember you can always use this mousse recipe for a simple dessert piped into glasses and layered with whatever you see fit and turn it into a trifle as I did here!

In the video I made a small 5″ Mousse Cake but here I have adjusted the recipe to make 1-8″ cake
You will need an 8″ ring mold or a springform pan to make this cake.
Acetate cake strips are also really helpful for a perfectly unmold-able cake with perfect smooth sides for glazing

Serves: 10-14 people


  • Raw Cashews Soaked 2 cup (300g) * I soak my nuts in bulk then measure
  • Canned Pumpkin 2 cup (454g) *Fresh pumpkin has a higher liquid content so canned is best, or you will have to strain and then reduce your puree to a thicker consistency and then measure the 2 cups weight
  • Cocoa Butter ½ cup (113g)
  • Coconut Milk 1 cup (237ml)
  • Confectioner’s Sugar 2 cup (240g)
  • Aquafaba liquid from a can of chick peas ½ cup (120ml)
  • Agar ½ teaspoon


  1. First prepare the ginger cake recipe below and while it is cooling you can prepare the pumpkin mousse as follows:
  2. First prepare the stabilized aquafaba by heating it over low heat with the agar powder and bring it to a boil. Boil just for about 30 seconds to activate the agar, then 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
  3. Combine the soaked cashews, pumpkin, confectioner’s sugar and coconut milk in a high speed blender of food processor and blend smooth on high for about 45 seconds
  4. Slowly pour the melted cocoa butter through the feed tube and continue processing for another 15 seconds
  5. Transfer to a large mixing bowl
  6. Whip the cooled (or room temperature aquafaba) with a balloon whip attachment to stiff glossy peaks and then fold into the pumpkin mixture
  7. Fold the aquafaba meringue into the pumpkin mousse base then pour into the prepared mold, add the gingerbread cake layer 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.
  8. Prepare theganache recipe (link below) below then unmold the cake and ice as shown in the video
