Step‑by‑Step Instructions for Vegan Chocolate Mousse Cake
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and prepare a 9-inch springform pan by lightly greasing it with vegan butter or lining the bottom with parchment paper. This ensures the cake releases easily once baked. As the oven warms up, gather all your ingredients to streamline the cooking process.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine 1 cup all-purpose flour, 1/2 cup cocoa powder, 1 teaspoon baking powder, 1 teaspoon baking soda, and a pinch of salt. Whisk together until the dry ingredients are well-blended and there are no lumps. This mixture will provide the structure needed for your Vegan Chocolate Mousse Cake.
Step 3: Mix Wet Ingredients
In a separate bowl, mix together 1 cup granulated sugar and 1 cup vegan milk until fully dissolved. Ensure to use a whisk for a smooth consistency. This wet mix adds moisture and sweetness to the cake. Once combined, it’ll create a lovely contrast to the dry ingredients you prepared earlier.
Step 4: Combine Mixtures
Now, gently pour the wet mixture into the bowl of dry ingredients. Using a spatula, gently mix until just combined, being careful not to over-mix. You want to maintain the fluffy texture that makes your vegan chocolate mousse cake light and airy. A few lumps are perfectly fine!
Step 5: Bake the Cake
Transfer the batter into your prepared springform pan, smoothing the top with a spatula. Bake in the preheated oven for 20 minutes, or until a toothpick inserted into the center comes out clean. The cake should spring back lightly when touched; this ensures it’s perfectly baked.
Step 6: Cool the Cake
Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes. Then, carefully release the springform mechanism and place the cake on a wire rack. Allow it to cool completely before adding the layers of luscious mousse.
Step 7: Prepare the Mousse
In a separate bowl, whip 1 cup vegan heavy cream using a hand mixer or stand mixer until soft peaks form. This will take about 3–4 minutes. Once whipped, gently fold in 1 cup melted vegan chocolate chips until fully combined. The mousse should be rich and creamy, ready to layer onto your cake.
Step 8: Layer the Mousse
Slice the cooled cake horizontally into two equal layers. Place one layer on a serving plate and generously spread half of the mousse mixture evenly on top. Layer the second cake half on top and spread the remaining mousse over it, smoothing the surface. Refrigerate for at least 3 hours to let the flavors meld beautifully.
Step 9: Make the Ganache
To prepare the ganache, melt 1 cup vegan chocolate chips and 2 tablespoons vegan butter together in a small saucepan over low heat, stirring constantly. Once melted and smooth, remove from heat and let cool slightly. This glossy ganache will enhance your vegan chocolate mousse cake, adding a touch of decadence.
Step 10: Top with Ganache
Once the mousse has set, pour the ganache over the chilled cake, allowing it to drip down the sides for an appealing finish. Use a spatula to help spread it evenly if needed. Chill again for about 30 minutes to ensure your ganache sets beautifully, creating a stunning presentation.
Step 11: Slice and Serve
After the final chill, carefully slice your Vegan Chocolate Mousse Cake with a sharp knife. Serve immediately and watch your loved ones enjoy this light yet decadent dessert. Remember, each bite reveals layers of airy chocolate mousse that melds with the rich ganache for an irresistible experience.

Ridiculously Easy Vegan Chocolate Mousse Cake Recipe FAQs
What kind of cocoa powder should I use for the cake?

What if my vegan heavy cream doesn’t whip well?
If your vegan heavy cream isn’t whipping up to soft peaks, try chilling your bowl and beaters in the freezer for about 10 minutes before whipping. This helps the cream whip more effectively. Alternatively, consider using a brand like Cocowhip that is known for its superior whipping qualities.
Is this cake suitable for those with nut allergies?
Yes! This Vegan Chocolate Mousse Cake is made without any nuts, so it’s a safe choice for those with nut allergies. Just make sure to check the labels on your ingredients to ensure they’re also free from nut cross-contamination. Enjoy your cake worry-free!
