- 1 1/2 cups (188 g) all-purpose flour or gluten-free 1:1 baking flour, sifted
- 1/2 cup (48 g) Dutch-process cocoa powder, sifted
- 1 tsp baking powder
- 3/4 tsp baking soda
- 1/4 tsp sea salt
- 1 cup (200 g) granulated sugar
- 1/4 cup (55 g) light brown sugar
- 1/4 cup (57 g) unsalted vegan butter, melted and cooled to room temperature
- 1/2 cup (110 g) dairy-free yogurt, room temperature
- 1/2 tsp vanilla extract
- 1/2 cup (120 mL) HOT coffee (can be brewed or instant)
- 1 cup (240 g) vegan dairy-free chocolate
- 3 cups (720 mL) heavy vegan cream, divided and cold
- 1 batch vegan chocolate ganache
How to Make Vegan Chocolate Mousse Cake Step-by-Step
- Step 1: Prepare the cake layers: Whisk together sifted flour, sifted cocoa powder, baking powder, baking soda, and salt in a large bowl. In a separate bowl, whisk together granulated sugar, brown sugar, melted vegan butter, dairy-free yogurt, and vanilla extract until smooth. Gradually add the wet ingredients to the dry, alternating with dairy-free milk, mixing until just combined. Slowly pour in hot coffee while mixing on low speed until batter is thin.
- Step 2: Pour the batter evenly into two prepared 8-inch round cake pans. Bake in a preheated oven at 350°F (175°C) for 30-35 minutes, or until a toothpick comes out clean. Let cool in pans for 10-15 minutes before inverting onto a wire rack to cool completely.
- Step 3: Craft the vegan chocolate mousse: Gently melt vegan chocolate in a heatproof bowl over simmering water until smooth. Let cool slightly. In a chilled bowl, whip 2 cups of cold heavy vegan cream until stiff peaks form.
- Step 4: Gently fold the cooled melted chocolate into the whipped vegan cream in batches, being careful not to deflate the cream. Fold until just combined, creating a marbled effect.
- Step 5: Assemble the cake: Place one cooled cake layer on a serving plate. Spread half of the chocolate mousse over the layer. Top with the second cake layer and spread the remaining mousse over the top and sides.
- Step 6: Finish with ganache: Pour or spoon the vegan chocolate ganache over the mousse-covered cake. Use an offset spatula to spread it down the sides. Allow the ganache to set for at least 30 minutes in the refrigerator before serving.

- Use room temperature ingredients for better mixing.
- Ensure the vegan cream is cold for better whipping.
