Ingredients You’ll Need for Vegan Chocolate Mousse Cake

This recipe comes together in two parts: the cake base and the mousse topping. Each uses easy-to-find ingredients (listed below) to keep the texture rich and smooth.

For the Cake Base

1 cup all-purpose flour
⅓ cup unsweetened cocoa powder
¾ cup organic cane sugar
1 teaspoon baking soda
½ teaspoon salt
1 cup plant milk (almond, soy, or oat)
⅓ cup neutral oil
1 tablespoon apple cider vinegar
1 teaspoon vanilla extract

For the Chocolate Mousse Layer

1½ cups dairy-free dark chocolate chips
1 can (13.5 oz) full-fat coconut milk, chilled overnight
1 tablespoon maple syrup (optional, for extra sweetness)
1 teaspoon vanilla extract
Pinch of salt

Step-by-Step Instructions for Making Vegan Chocolate Mousse Cake

Each step plays a key role in building the rich, multi-layered experience this cake offers. Here’s how to make it:

Prepare your pan
Preheat the oven to 350°F (175°C). Line an 8-inch springform pan with parchment paper and lightly grease the sides.
Make the cake base
In a large bowl, whisk together flour, cocoa powder, sugar, baking soda, and salt. In a separate bowl, whisk together the plant milk, oil, vinegar, and vanilla. Pour the wet mixture into the dry and stir until just combined.
Transfer, bake, and cool
Transfer the batter to the prepared pan and bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean.
Let the cake cool completely in the pan.
Melt the chocolate
In a heat-safe bowl, melt the chocolate chips using a double boiler or microwave in short bursts, stirring until smooth. Set aside to cool slightly.
Whip the coconut cream
Scoop the solid part from the chilled can of coconut milk into a mixing bowl (discard or reserve the liquid for another use).
Add vanilla, maple syrup, and a pinch of salt. Using a hand mixer or stand mixer, whip until light and fluffy.
Make the mousse
Once the melted chocolate has cooled but is still pourable, gently fold it into the whipped coconut cream. Mix slowly until fully incorporated and smooth.
Assemble and chill
Spread the mousse evenly over the cooled cake base while it’s still in the springform pan. Smooth the top with a spatula.
Refrigerate the entire cake for at least 4 hours, or overnight, to allow the mousse to set completely.
Serve
Once set, release the cake from the springform pan and garnish as desired.

Toppings and Serving Ideas for Vegan Chocolate Mousse Cake

This cake looks and tastes wonderful on its own, but here are a few simple ways to add a little extra flair:

Shaved dairy-free chocolate or cacao nibs
Fresh raspberries or strawberries
A dusting of cocoa powder or powdered sugar
A drizzle of vegan chocolate sauce
Chopped hazelnuts or almonds for texture

How to Store Vegan Chocolate Mousse Cake

Vegan mousse cake is best served chilled. Store any leftovers covered in the refrigerator for up to 4 days.

The mousse layer will stay light and fluffy, and the flavor often deepens after a day or two.

For longer storage, individual slices can be frozen and thawed in the fridge before serving.

Fun Flavor Variations to Try

If you want to experiment with different flavors or textures, try one of these easy adjustments:

Add a tablespoon of espresso to the cake batter for a mocha twist
Fold in a few crushed cookies or nuts into the mousse layer
Add orange or peppermint extract for a seasonal variation
Use a chocolate cookie crust instead of the cake base for a no-bake option
