How to Make Pumpkin Chocolate Mousse Cake

Follow these steps to create your show-stopping dessert. This guide will walk you through how to make pumpkin chocolate mousse cake with beautiful layers.

Step 1: Preheat your oven to 350°F (175°C). Line a 9-inch round pan with parchment paper. In a large bowl, beat the unsalted butter with granulated sugar and brown sugar until the mixture is light and fluffy. Add the large egg and vanilla extract, mixing until just combined. Gradually incorporate the all-purpose flour, unsweetened cocoa powder, baking soda, and salt, alternating with the buttermilk. Pour the batter into the prepared pan. Bake for 22-25 minutes, or until a toothpick inserted into the center comes out clean. Let the chocolate cake cool completely before proceeding.
Step 2: Prepare a 9-inch springform pan by lining the inside with acetate or foil to help with easy removal. Place the completely cooled chocolate cake layer at the bottom of the prepared springform pan. This forms the base of your pumpkin chocolate cake with mousse filling.
Step 3: For the cinnamon mousse, gently melt the cinnamon chips with 1 cup of cold heavy cream over low heat until smooth and creamy. Let this mixture cool slightly. While it cools, bloom the unflavored powdered gelatin in a small amount of water according to package directions. Stir the bloomed gelatin into the slightly cooled cinnamon chip mixture until fully incorporated. Fold in 1 cup of whipped cream until light and airy. Spread this evenly over the chocolate cake layer. Refrigerate the pan for about 25 minutes, just until the layer begins to set.
Step 4: Next, prepare the pumpkin-butterscotch mousse. Melt the butterscotch chips with another 1 cup of cold heavy cream in a saucepan over low heat until smooth. Let it cool. In a separate bowl, combine the canned pumpkin puree with the remaining bloomed gelatin and stir well. Gently fold the pumpkin mixture into the cooled butterscotch mixture. Pour this over the set cinnamon mousse layer. Return the cake to the refrigerator for another 30 minutes to firm up.
Step 5: Now for the salted caramel mousse. Melt the salted caramel chips with 1 cup of cold heavy cream over low heat until just combined and smooth. Let it cool slightly. Fold in the final portion of bloomed gelatin. Once incorporated, gently fold in 1 cup of whipped cream to create a light mousse. Carefully pour this over the set pumpkin-butterscotch layer. Refrigerate this layer for another 30 minutes until firm.
Step 6: Finally, prepare the ganache. Heat 1 cup of cold heavy cream in a small saucepan until it just begins to steam – do not boil. Pour the hot cream over the chopped semi-sweet chocolate in a heatproof bowl. Let it sit for 2 minutes, then whisk gently until the chocolate is completely melted and the ganache is smooth and glossy. Let the ganache cool slightly until it’s pourable but not hot. Carefully pour it over the top of the chilled mousse layers, allowing it to cascade beautifully down the sides of your cake.
Step 7: Chill the completed Pumpkin Chocolate Mousse Cake in the refrigerator for at least 4 hours, or preferably overnight, to allow all the layers to set completely.
Step 8: For the most elegant presentation, carefully run a hot knife (dipped in hot water and wiped dry) around the edge of the springform pan before releasing it. Slice the cake with the same hot knife for clean, beautiful servings.

Pro Tips for the Best Pumpkin Chocolate Mousse Cake

Creating this masterpiece is all about patience and attention to detail. Here are my top tips to ensure your pumpkin chocolate mousse cake turns out absolutely perfect every single time.

Make sure your heavy cream is ice-cold before whipping; it’s crucial for achieving light, airy mousse layers.
Don’t rush the chilling process between layers; allowing each mousse to set properly prevents them from mixing together.
For the smoothest ganache, ensure your cream is hot but not boiling when poured over the chocolate.
Taste your mousse mixtures before folding in the whipped cream – a little extra spice or salt can make a big difference!

Best Ways to Serve Pumpkin Chocolate Mousse Cake

This spectacular dessert is a showstopper on its own, but a few serving suggestions can elevate it even further. Imagine slicing into this beauty after a hearty meal; it’s pure bliss!

Serve chilled slices on their own to truly appreciate the intricate layers of mousse and rich chocolate cake.

Why is my pumpkin chocolate mousse cake runny?

A runny pumpkin chocolate mousse cake usually means the gelatin wasn’t bloomed or incorporated correctly, or the cake wasn’t chilled long enough for the layers to set.

Variations of Pumpkin Chocolate Mousse Cake You Can Try

This incredible dessert is so versatile! While this recipe is a showstopper, I love experimenting with different versions. Here are a few ideas to inspire your next bake:

Vegan Pumpkin Chocolate Mousse Cake: To create a delicious vegan pumpkin chocolate mousse cake, swap out the dairy products for plant-based alternatives. Use vegan butter, a flax egg or commercial egg replacer, plant-based milk like almond or soy, and full-fat coconut cream for the whipped elements. Ensure your chocolate and chips are also dairy-free.
Gluten-Free Pumpkin Chocolate Mousse Cake: For a gluten-free pumpkin chocolate mousse cake, simply substitute the all-purpose flour with a good quality gluten-free baking blend in the chocolate cake layer. Make sure the blend contains xanthan gum for structure. All mousse layers are naturally gluten-free, making this an easy adaptation!
Dairy-Free Pumpkin Chocolate Mousse Cake: Achieving a dairy-free pumpkin chocolate mousse cake is similar to the vegan version. Focus on using dairy-free butter, milk, chocolate, and chips. Coconut cream works wonderfully for creating the light mousse texture without any dairy.
Spiced Pumpkin Chocolate Mousse Cake: Amp up the fall flavors by adding a pinch more cinnamon, nutmeg, and a hint of cloves to the cake batter and mousse layers. This version truly embraces the essence of the season.
