I am so glad to be able to share this amazing dessert, Chocolate Pumpkin Mousse Cake, an elegant dessert with an irresistible flavor combination perfect for upcoming holidays. If you love pumpkin you should definitely try this recipe, as it is one of the best pumpkin desserts ever. I really love pumpkin, and I have used it in many recipes here on my blog and channel, but this dessert might be my new favorite from all pumpkin desserts.

This cake has a moist chocolate cake at the bottom, followed by a spiced and creamy pumpkin mousse, a chocolate mousse on top, finished with a shiny layer of dark chocolate ganache, decorated with beautiful physalis and cinnamon sticks to create a perfect fall dessert.

The recipe is quite easy and quick to prepare, you can easily make this a no-bake dessert if you substitute the chocolate cake at the bottom with an oreo crust or your favorite cookie crust. Hope you will try it out and enjoy!

    This was a fun challenge for a Thanksgiving dessert. I wanted to make something with pumpkin, but avoid a basic pumpkin pie. This was incredible and a showstopper! The pumpkin mousse was my favorite part. This was the second recipe of yours that I’ve tried and each one is a fun, new adventure!

  3. Your recipes and videos are so well explained. Thank you so much. I look forward to trying this mousse cake.

    I didn’t have luck with this recipe and was disappointed with the outcome. The flavor of the pumpkin mousse was off and the whole thing was bland.

    1. Ella - Home Cooking Adventure Author says:

      I wonder what happened. It is a very flavorful cake, not bland at all. It is important to use good quality chocolate and if possible fresh roasted pumpkin. I never use canned pumpkin. What kind of pumpkin did u use? Also, it is a must to use all the spices mentioned, ginger, cinnamon, nutmeg and cloves, to bring that fall specific flavor. If you follow exactly each step the cake will turn awesome and bursting with flavor.

    This was AMAZING. I can’t believe how much this recipe exceeded my expectations. This might be one of the best mousse desserts I have ever made, the texture was perfect. Better than cakes I’ve literally bought. The ingredients and multiple layers kind of intimidated me at first but it wasn’t too hard. I used cling wrap instead of acetate and it came out with wrinkly edges but was still pretty. Thank you for the recipe 🙂
