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 unsalted butter and sugars until fluffy, about 3 minutes. Add the large egg and vanilla extract, mixing until combined. Gradually incorporate the all-purpose flour, unsweetened cocoa powder, baking soda, and buttermilk, alternating between dry and wet ingredients. Pour the batter into the prepared pan and bake for 22-25 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely on a wire rack.
Step 2: Make the Cinnamon Mousse Layer
In a saucepan, melt the cinnamon chips with the heavy cream over low heat, stirring occasionally until completely smooth. Remove from heat and stir in the canned pumpkin puree. Allow the mixture to cool slightly, then prepare the unflavored powdered gelatin by sprinkling it over 2 tablespoons of cold water and letting it sit for 5 minutes until softened. Stir the gelatin into the cinnamon mixture, then gently fold in whipped cream until fully combined. Spread this luscious cinnamon mousse over the cooled chocolate cake layer, smoothing the top with a spatula.
Step 3: Prepare the Pumpkin-Butterscotch Mousse Layer
In the same saucepan, melt the butterscotch chips with another portion of heavy cream over low heat, stirring until smooth. After cooling the mixture for a few minutes, prepare another batch of gelatin as before and mix it into the butterscotch blend. Once combined, fold in whipped cream to create a light mousse. Carefully layer this pumpkin-butterscotch mousse over the cinnamon mousse, using a spatula to create an even surface.
Step 4: Create the Salted Caramel Mousse Layer
Melt the salted caramel chips with the remaining heavy cream in a saucepan over low heat, stirring until fully blended. Mix in the thick salted caramel sauce for added richness and flavor. Allow this to cool slightly, then prepare and stir in the gelatin, followed by gently folding in whipped cream. Pour this decadent salted caramel mousse layer over the previous butterscotch mousse, smoothing it out to ensure a beautiful finish.
Step 5: Make the Ganache
To prepare the ganache, heat the remaining heavy cream in a saucepan just until it begins to simmer. Remove it from the heat and pour it over chopped semi-sweet chocolate in a bowl, allowing it to sit for a few minutes. Stir until smooth and glossy, ensuring there are no lumps. Once the ganache cools slightly, pour it over the fully set mousse layers, allowing it to coat evenly for a stunning finish.
Step 6: Chill the Cake
Refrigerate your Pumpkin Chocolate Mousse Cake for at least 4 hours, or preferably overnight, to let the mousse layers set properly. This chilling time is crucial to achieving distinct and delightful textures. Ensure it’s covered lightly with plastic wrap to prevent any absorption of odors in the fridge.
Step 7: Finish & Serve
When ready to serve, remove the cake from the refrigerator and decorate the top with dollops of whipped cream. For an added touch, sprinkle with ground cinnamon and chocolate candies for a festive autumn look. Slice through the beautifully layered cake with a hot, dry knife to achieve clean edges, and prepare to impress your loved ones with this irresistible Pumpkin Chocolate Mousse Cake!

Pumpkin Chocolate Mousse Cake Recipe FAQs
How do I select the best pumpkin puree for this cake?
Absolutely! When choosing pumpkin puree, look for a can labeled “100% pumpkin” without any added sugars or spices. If using fresh pumpkin, select a small sugar pumpkin or pie pumpkin, which has a sweeter, more concentrated flavor than larger varieties. Aim for a smooth and vibrant orange flesh.
What is the best way to store leftover Pumpkin Chocolate Mousse Cake?
To keep your cake fresh, store it in an airtight container in the refrigerator for up to 3 days. The rich flavors will blend beautifully, making each slice even more delightful. For longer storage, wrap the cake tightly in plastic wrap and aluminum foil, and it can be frozen for up to 2 months. Just remember to thaw it overnight in the refrigerator before serving!
Can I make changes to this recipe for dietary restrictions?
Very! This Pumpkin Chocolate Mousse Cake can easily accommodate different dietary needs. To make it gluten-free, substitute the all-purpose flour with a gluten-free blend. For a dairy-free version, use coconut oil instead of butter, and substitute heavy cream with coconut cream. You can also replace gelatin with agar-agar for a vegetarian option. Adjusting ingredients can still yield a delicious cake that everyone will enjoy.
What should I do if the mousse layers don’t set properly?
If your layers don’t set as expected, don’t worry! First, ensure the gelatin is fresh and properly hydrated. If the mousse is too soft, chill it longer in the refrigerator. If you have a softer layer, you can try to stir in additional whipped cream to lighten it. Just ensure every layer is chilled before adding the next! It takes patience, but creating distinct layers is totally worth it.
Can I freeze the Pumpkin Chocolate Mousse Cake?
Absolutely! To freeze, wrap your fully set cake tightly in plastic wrap, ensuring no air can enter. Then, cover it with aluminum foil for extra protection against freezer burn. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy, just transfer it to the refrigerator to thaw overnight—perfectly delicious once again!
Can pets eat any part of this cake?
No, it’s best to avoid sharing this dessert with pets. Ingredients like chocolate, sugar, and heavy cream can be harmful to dogs and cats. Always keep your treats safely out of reach of your furry friends!
