Step‑by‑Step Instructions for Pumpkin Chocolate Mousse Cake
Step 1: Prepare the Chocolate Cake
Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan. In a large mixing bowl, cream together room-temperature unsalted butter, granulated sugar, and brown sugar until light and fluffy, about 3-4 minutes. Add in a room-temperature egg and vanilla extract, mixing well. Gradually incorporate the dry ingredients along with buttermilk until combined. Pour the batter into the prepared pan and bake for 22-25 minutes, or until a toothpick inserted in the center comes out clean. Cool the cake completely on a wire rack.
Step 2: Make the Cinnamon Mousse Layer
In a medium saucepan over low heat, melt the cinnamon chips with 1 cup of heavy cream until smooth. Remove from heat and stir in the pumpkin puree. In a small bowl, dissolve the unflavored powdered gelatin in cold water per the packet instructions, then mix it into the pumpkin mixture. Allow to cool slightly, then gently fold in whipped cream until no streaks remain. Once the chocolate cake has cooled, spread the cinnamon mousse layer evenly on top.
Step 3: Prepare Pumpkin-Butterscotch Mousse Layer
Melt butterscotch chips with 1 cup of heavy cream in a saucepan over low heat, stirring until smooth. Remove from heat and let cool. Meanwhile, dissolve gelatin in cold water as directed. Once cooled, mix the gelatin into the butterscotch mixture and fold in whipped cream until well combined. Carefully layer this mixture over the cinnamon mousse, smoothing it out with a spatula.
Step 4: Create Salted Caramel Mousse Layer
To make the salted caramel mousse, melt the salted caramel chips with 1 cup of cream in a saucepan over low heat, stirring until silky. Remove from heat and allow to cool, then mix in the thick salted caramel sauce. Prepare the gelatin by dissolving it in cold water per instructions. Incorporate the gelatin into the cooled caramel mixture, then carefully fold in whipped cream to lighten. Spread this layer on top of the butterscotch mousse, smoothing it out.
Step 5: Make Ganache
For the ganache, heat the remaining 1 cup of heavy cream in a saucepan until it simmers. Remove from heat and pour it over the chopped semi-sweet chocolate in a heatproof bowl. Let it sit for a couple of minutes, then stir until smooth and glossy. Allow the ganache to cool slightly before pouring it over the layered mousses, ensuring an even coating.
Step 6: Chill to Set
Cover the Pumpkin Chocolate Mousse Cake with plastic wrap and refrigerate it for at least 4 hours, or overnight for the best results. This chilling time helps the layers set properly and meld the flavors together for a deliciously rich dessert.
Step 7: Finish Cake and Serve
Once set, remove the cake from the fridge. Decorate the top with dollops of whipped cream and sprinkle with chocolate candies for an elegant touch. Use a hot, dry knife to slice cleanly through the layers, revealing the beautiful Pumpkin Chocolate Mousse Cake inside as you serve it to your delighted guests.

-
Room Temperature Matters: Make sure all your ingredients, especially butter and eggs, are at room temperature. This ensures a smooth batter for your Pumpkin Chocolate Mousse Cake.

Pumpkin Chocolate Mousse Cake Recipe FAQs
What type of pumpkin should I use for the mousse?
You can use either canned pumpkin puree or fresh pumpkin puree for this recipe. If using fresh, be sure to cook and puree it thoroughly until smooth. Canned pumpkin is convenient and offers consistent results, which I often prefer when making this decadent Pumpkin Chocolate Mousse Cake.
How long can I store the Pumpkin Chocolate Mousse Cake in the fridge?
Leftover cake can be stored wrapped tightly in plastic wrap in the refrigerator for up to a week. It’s a great make-ahead dessert since the flavors improve with time! Just be sure to keep it well-wrapped to maintain that lovely layered texture.
Can I freeze the Pumpkin Chocolate Mousse Cake?
Absolutely! For longer storage, wrap individual slices tightly in plastic wrap, then place them in an airtight container or freezer bag to prevent freezer burn. The cake can be frozen for up to 2 months. Just remember to thaw the slices in the fridge overnight before serving to keep the mousse perfectly creamy.
What should I do if my mousse layers don’t set properly?
No worries—this can happen sometimes. Ensure your gelatin is properly dissolved and fully incorporated into the mousse mixture. If the mousse still doesn’t set, it might need an extra hour in the fridge. Next time, try using a higher ratio of gelatin to liquid or chill the mousse layers longer before adding them to the cake.
What are some gluten-free substitutes I can use for the cake?
For a gluten-free Pumpkin Chocolate Mousse Cake, simply replace the all-purpose flour with a gluten-free flour blend. Many all-purpose gluten-free flours contain xanthan gum, which helps provide the structure needed for your cake. I recommend mixing it thoroughly to ensure there are no lumps.
Is this cake suitable for people with dairy allergies?
Yes! You can easily make this Pumpkin Chocolate Mousse Cake dairy-free by substituting the heavy cream with coconut cream and using a dairy-free butter alternative. Make sure any chocolate or chips used are dairy-free as well. Your loved ones will enjoy it just as much!
