Step‑by‑Step Instructions for Ridiculously Easy Vegan Chocolate Mousse Cake
Step 1: Prepare the Cake Batter
In a large mixing bowl, sift together gluten-free flour, coconut sugar, cocoa powder, baking powder, and a pinch of salt. In a separate bowl, whisk together your plant milk and vanilla extract. Gradually combine the wet ingredients with the dry ingredients, stirring until the batter is smooth and well mixed—this should take about 2 minutes.
Step 2: Bake the Cake
Preheat your oven to 350°F (175°C) and grease a springform pan with a little oil. Pour the cake batter into the prepared pan, ensuring an even layer. Bake for 20 minutes, or until a toothpick inserted into the center comes out clean. Once baked, allow the cake to cool completely in the pan before transferring it to a wire rack.
Step 3: Make the Mousse
Pour vegan heavy cream into a mixing bowl that has been chilled in the refrigerator. Using a hand mixer, whip the cream until soft peaks form, taking about 3–4 minutes. In a separate bowl, melt your vegan chocolate chips in the microwave in 30-second intervals, stirring until smooth. Fold the melted chocolate into the whipped cream gently until fully incorporated and creamy.
Step 4: Chill the Mousse
Once the mousse is well mixed, transfer it to the refrigerator to chill for at least 30 minutes. This helps it set to the perfect fluffy consistency for layering. During this time, prepare your ganache so it’s ready once the mousse is set.
Step 5: Prepare the Ganache
In a small saucepan, heat coconut cream over medium-low heat until it’s warm but not boiling. Remove from heat and add in your vegan chocolate chips, stirring until you achieve a smooth, glossy ganache. This step should only take about 2-3 minutes. Set aside to cool slightly before assembling.
Step 6: Assemble the Cake
Once the cake has completely cooled, carefully remove it from the springform pan. Place the cake on a serving platter. Spread the chilled mousse layer evenly over the top of the cake, creating an enticing layer of fluffiness that will complement the cake base beautifully.
Step 7: Add Ganache and Chill
Pour the ganache over the mousse layer, smoothing it out with a spatula if necessary for an even finish. Once the ganache is set, cover the cake and refrigerate for at least 3 hours to allow all layers to meld together and enhance the flavor of the Vegan Chocolate Mousse Cake.
Step 8: Serve and Enjoy
After chilling, slice your decadent Vegan Chocolate Mousse Cake with a sharp knife dipped in warm water for clean cuts. Serve chilled, and prepare for compliments from your guests on this beautifully crafted dessert.

Vegan Chocolate Mousse Cake Recipe FAQs
How do I ensure my cake doesn’t sink after baking?
To prevent sinking, make sure all your ingredients are fresh and at room temperature. After mixing the batter, immediately pour it into the prepared pan and bake it right away. Avoid opening the oven door during baking, as temperature fluctuations can impact your cake’s rise. Lastly, using the right mixing technique—mixing just until combined—helps to avoid incorporating too much air.
What should I look for when selecting ripe ingredients?
When choosing vegan chocolate chips, look for brands with a clear label indicating they’re dairy-free. For coconut cream, ensure it’s a consistent texture without any separation in the can, as this will yield a smooth ganache. If using aquafaba, pick up canned chickpeas that have a liquid consistency—this will provide the best results for your mousse.
How long can I store the Vegan Chocolate Mousse Cake in the fridge?
You can store the cake in an airtight container in the refrigerator for up to 3 days. This helps maintain its delightful texture and flavor, ensuring it remains just as delicious as when it was first made!
Can I freeze Vegan Chocolate Mousse Cake, and if so, how?
Absolutely! To freeze your cake, wrap it tightly in plastic wrap followed by aluminum foil or place it in an airtight container. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it again, simply thaw it overnight in the fridge before serving. This way, you’ll have a rich dessert ready to impress at a moment’s notice!
Is there a vegan substitute for egg-based dishes if I have allergies?
Yes, aquafaba (the liquid from canned chickpeas) is a fantastic egg alternative in this recipe. It mimics the properties of egg whites, providing stability and fluffiness to the mousse without compromising the cake’s delightful vegan quality.
What adjustments can I make for optimal gluten-free results?
When using gluten-free flour, opt for a blend that includes xanthan gum or similar binding agents, which help replicate the texture of traditional flour. I often recommend testing with a reputable gluten-free blend and double-checking the conversion ratios to ensure perfect results in your Vegan Chocolate Mousse Cake.
