Step‑by‑Step Instructions for Dark Chocolate Mousse Cake
Step 1: Prepare the Cake
Preheat your oven to 350ºF (180ºC) while greasing and lining a 9-inch springform pan with parchment paper. This will ensure your cake releases easily after baking. Once the oven is ready, you’ll be prepared to create a rich chocolate base that forms the foundation of your Dark Chocolate Mousse Cake.
Step 2: Mix Dry Ingredients
In a large bowl, combine 1 cup of all-purpose flour, ½ cup of Dutch cocoa powder, 1 teaspoon of espresso powder, 1 teaspoon of baking powder, ½ teaspoon of baking soda, and a pinch of fine sea salt. Whisk the mixture until well blended, ensuring there are no lumps. This mixture adds deep chocolate flavor and lightness to your cake.
Step 3: Combine Wet Ingredients
In a separate bowl, using a whisk, combine 1 cup of granulated white sugar, ½ cup of neutral oil, 1 cup of full-fat sour cream, 1 large egg, and 1 teaspoon of vanilla extract until smooth. The wet ingredients create a creamy consistency that will blend seamlessly with your dry ingredients, ensuring your cake is moist and delicious.
Step 4: Combine Dry & Wet Ingredients
Sift the dry ingredients into the bowl with the wet mixture, folding gently to combine. Then, slowly incorporate 1 cup of boiling water, stirring until just blended—take care not to overmix! The batter will be thin but will bake beautifully, becoming a luscious base for your Dark Chocolate Mousse Cake.
Step 5: Bake
Pour the batter into your prepared springform pan and bake in the preheated oven for 24-28 minutes. You’ll know it’s done when a toothpick inserted in the center comes out clean. Once baked, remove from the oven and allow the cake to cool completely in the pan on a wire rack.
Step 6: Prepare Mousse
In a saucepan, whisk together 1 cup of heavy cream, 1 large egg, 1 egg yolk, ¼ cup of granulated sugar, 2 tablespoons of cocoa powder, and a pinch of salt. Heat gently over low to medium heat, stirring continuously until the mixture reaches 170ºF (76ºC). This step is essential for creating a silky texture in your chocolate mousse.
Step 7: Add Chocolate
Remove the saucepan from heat and immediately stir in 8 ounces of finely chopped dark chocolate and 1 teaspoon of vanilla extract. Mix until the chocolate is completely melted and the mixture is smooth. Let it cool at room temperature until it thickens slightly—this will form the rich mousse layer of your cake.
Step 8: Whip Cream and Combine
In a separate mixing bowl, whip 1 cup of heavy cream until firm peaks form. Carefully fold the whipped cream into the cooled chocolate mixture, combining them gently to maintain the airy texture. This light and fluffy mousse will be a delightful contrast to the rich cake, highlighting the flavors of the Dark Chocolate Mousse Cake.
Step 9: Assemble Cake
Reinsert the cooled cake into the springform pan. Carefully pour the prepared mousse over the cake layer, smoothing the top with a spatula. Chill the cake in the refrigerator for a minimum of 8 hours, allowing the mousse to set properly and develop its flavors.
Step 10: Make Ganache
To make the ganache, heat ½ cup of heavy cream in a small saucepan until it almost reaches a simmer. Pour the hot cream over 6 ounces of finely chopped dark chocolate in a bowl. Stir until the mixture is completely smooth, then let it cool slightly before using. This velvety ganache will crown your cake with a luxurious finish.
Step 11: Finish Cake
Once the mousse has set, carefully remove the cake from the springform pan. Pour the cooled ganache over the mousse layer, ensuring it evenly coats the top. Chill the cake briefly to allow the ganache to firm up before slicing into this decadent Dark Chocolate Mousse Cake and serving it to your eager guests.
How to Store and Freeze Dark Chocolate Mousse Cake
Fridge: Store the cake covered in the refrigerator for up to 5 days. This helps maintain its freshness and prevents the mousse from becoming overly soft.
Freezer: If you want to keep the cake longer, wrap it tightly in plastic wrap and foil, then freeze for up to 3 months. Thaw in the fridge overnight before serving.
Reheating: This cake is best enjoyed chilled; however, if you prefer a warm slice, you can gently microwave it for 10-15 seconds.
Assembling Tips: If you freeze individual slices, allow them to set in the freezer for about 2 hours before wrapping to preserve the beautiful layers of the dark chocolate mousse cake.

Dark Chocolate Mousse Cake Recipe FAQs
How do I choose the right dark chocolate for this cake?
Absolutely! For the best results, opt for high-quality dark chocolate with a cocoa content between 60%-70%. Brands like Ghirardelli or Lindt are excellent choices and will provide a rich, intense chocolate flavor for both the mousse and the ganache. Make sure to chop the chocolate finely before melting to ensure it melts evenly and smoothly.
Can I substitute any ingredients for dietary restrictions?
Very! If you need a gluten-free option, simply replace the all-purpose flour with a gluten-free blend that measures 1-to-1. For an eggless version, you can use 1/4 cup of silken tofu blended until smooth in place of each egg. Just ensure the tofu is well-incorporated for that rich mousse texture you desire. I often experiment with these alternatives, and they work beautifully!
How do I store the dark chocolate mousse cake?
Of course! After assembling the cake, cover it tightly with plastic wrap or place it in an airtight container. You can store it in the refrigerator for up to 5 days. This helps keep the mousse fresh and prevents any odors from passing through. Just remember, it’s best to keep it chilled to maintain that perfect texture!
Can I freeze the dark chocolate mousse cake?
Yes, indeed! To freeze this delightful cake, wrap it tightly in plastic wrap and then in aluminum foil, ensuring there are no air pockets. It can last in the freezer for up to 3 months. When you’re ready to enjoy it, simply place it in the refrigerator overnight to thaw, preventing any unpleasant texture surprises. For best results, I recommend freezing individual slices to make serving easier!
What should I do if my mousse doesn’t thicken?
If your mousse hasn’t thickened after cooling, it could be because it wasn’t heated to the right temperature initially. Make sure to gently heat the mixture to 170ºF (76ºC) while stirring constantly. If it still hasn’t thickened, try whipping additional cream to firm peaks and folding that into your mixture. Be patient, and carefully combine until it’s just right for your cake layers!
Is this cake pet-friendly?
It’s best to keep this cake away from pets, especially chocolate, as it can be toxic to dogs and cats. Make sure to enjoy your decadent dark chocolate mousse cake yourself and save some pet-friendly treats for your furry friends!
