Step‑by‑Step Instructions for Vegan Chocolate Mousse Cake
Step 1: Prepare Cake Batter
Begin by preheating your oven to 350°F (175°C). In a large mixing bowl, combine your vegan chocolate cake mix and any additional wet ingredients as directed on the packaging. Stir until you achieve a smooth batter, avoiding lumps. Once blended, pour the cake batter into a greased springform pan, spreading it evenly so that it bakes uniformly.
Step 2: Bake Cake
Place the springform pan in the preheated oven and bake for approximately 20 minutes. To check for doneness, insert a toothpick into the center; it should come out clean or with a few moist crumbs. Once baked, carefully remove the cake from the oven and allow it to cool completely in the pan on a wire rack.
Step 3: Make Mousse
While the cake cools, prepare the mousse. In a chilled mixing bowl, whip the vegan heavy cream on high speed until stiff peaks form, which usually takes about 3-5 minutes. Gently fold in the melted dark chocolate along with the coconut sugar until smooth and well combined, creating a rich, creamy mousse for the Vegan Chocolate Mousse Cake.
Step 4: Layer Mousse
Once the cake is entirely cool, spread a generous layer of chocolate mousse over the top, smoothing it out for an even finish. Place the cake in the refrigerator to chill and set for at least 3 hours. This cooling time allows the mousse to firm up, creating that delightful texture everyone loves.
Step 5: Prepare Ganache
For the luscious chocolate ganache, melt additional dark chocolate with a small amount of vegan heavy cream in a heatproof bowl over a pot of simmering water, stirring until smooth. Alternatively, you can microwave in short bursts, stirring in between. Once melted, pour the ganache over the chilled mousse, ensuring it covers the entire surface evenly.
Step 6: Chill Again
Return the assembled Vegan Chocolate Mousse Cake to the refrigerator and allow it to chill for at least another 30 minutes. This step allows the ganache to set firmly, ensuring that every slice is both visually appealing and perfectly structured.
Step 7: Serve
When ready to serve, carefully remove the sides of the springform pan. Using a sharp knife, slice the cake into generous portions. The rich layers of chocolate and mousse will create a stunning presentation that’s sure to impress everyone gathered around the table.

Make Ahead Options
This Ridiculously Easy Vegan Chocolate Mousse Cake is perfect for meal prep, allowing you to enjoy a scrumptious dessert with minimal fuss on busy days!

When you’re ready to serve, spread the mousse over the cake, prepare the ganache, and chill the assembled cake until set. This makes for a delightful treat that still tastes just as incredible, even days later!

Expert Tips for Vegan Chocolate Mousse Cake
-
Chill Your Bowl: Use a very cold bowl when whipping the vegan heavy cream. This helps achieve stiff peaks for a light and airy mousse.
-
Quality Chocolate Matters: Choose high-quality dark chocolate for the best flavor. Lower quality chocolates can lead to a waxy texture and lackluster taste in your Vegan Chocolate Mousse Cake.
-
Watch the Whipping: Avoid overwhipping the vegan heavy cream as it can curdle. Stop when stiff peaks form for a smoother mousse.
-
Patience is Key: Allow sufficient chilling time, at least three hours for the mousse and 30 minutes for the ganache, to ensure everything sets perfectly, enhancing the overall structure and texture.
-
Easy Substitutions: If you need to, granulated sugar works as a substitute for coconut sugar, but it will slightly alter the flavor. Keep the salt for balance!
-
Layer Wisely: For added texture, layer the mousse and cake generously; this creates a beautiful contrast that is sure to impress when serving your Vegan Chocolate Mousse Cake.

Ridiculously Easy Vegan Chocolate Mousse Cake Recipe FAQs
What type of chocolate should I use for the mousse and ganache?
Absolutely! It’s best to use high-quality dark chocolate with at least 60% cacao content for the richest flavor in your Vegan Chocolate Mousse Cake. Brands like Ghirardelli or Lindt offer great options. Avoid using chocolate chips that may contain added wax, as they can affect the smooth texture you want for the mousse and ganache.
How should I store the Vegan Chocolate Mousse Cake?
To keep your cake fresh, store any leftovers in an airtight container in the refrigerator for up to 2 days. This helps maintain its fluffy texture. If you want to keep it longer, you can freeze it for up to 2 months. Just wrap it tightly in plastic wrap and then aluminum foil to prevent freezer burn.
Can I freeze the Vegan Chocolate Mousse Cake?
Definitely! Freezing is a fantastic option. When you’re ready to freeze, allow the cake to set completely in the fridge first, then wrap it carefully in plastic wrap, followed by a layer of aluminum foil. For best results, freeze it flat. To enjoy, just move it to the fridge for about 6-8 hours before serving to let it thaw gently.
How do I solve common issues with the mousse?
If your mousse doesn’t whip up to stiff peaks, try chilling the bowl and beaters before whipping the vegan cream. Also, ensure you’re not overwhipping, as this can lead to a grainy texture. If you face a runny mousse, it might need more chilling time or a bit more chocolate folded in to help stabilize it.
Is this cake suitable for people with allergies?
Very! This Vegan Chocolate Mousse Cake is completely free of dairy and eggs, making it suitable for those with lactose intolerance or egg allergies. For gluten-sensitive individuals, just make sure to use gluten-free flour in the cake. However, always be cautious about other allergens like specific brands of chocolate or cream, which might vary.
