If you love deep chocolate flavor with a hint of espresso warmth, this Mocha Chocolate Velvet Mousse Cake is the dessert you’ve been waiting for. Elegant, rich, and layered with silky textures, this cake combines a soft chocolate sponge, airy mocha mousse, and a glossy chocolate glaze that melts in every bite.
This is not just a cake — it’s a pastry-level dessert experience. The balance of chocolate and coffee creates depth without overpowering sweetness, making it perfect for celebrations, dinner parties, or any moment that deserves something extraordinary.
Despite its luxurious appearance, this cake is surprisingly achievable at home. With careful layering and simple pastry techniques, you can create a dessert that looks like it came straight from a high-end bakery.
What Makes This Cake Special?
The magic of this mousse cake lies in its contrast of textures:
- Soft, tender chocolate sponge base
- Light and airy mocha mousse layer
- Smooth, glossy chocolate glaze
Each layer serves a purpose. The sponge anchors the dessert, the mousse adds lightness, and the glaze provides richness and visual elegance. The coffee doesn’t make the cake taste like coffee — it intensifies the chocolate and adds a warm, sophisticated finish.
This is why professional pastry chefs often pair espresso with chocolate: it enhances flavor complexity without stealing the spotlight.

- 120 g (1 cup) all-purpose flour
- 30 g (¼ cup) cocoa powder
- 150 g (¾ cup) sugar
- 2 large eggs, room temperature
- 100 ml (½ cup) milk
- 80 ml (⅓ cup) vegetable oil

Mocha Chocolate Mousse
- 200 g dark chocolate (60–70%)
- 1 tbsp instant coffee dissolved in 1 tbsp hot water
- 300 ml (1¼ cups) cold heavy cream
- 2 tbsp powdered sugar
- 1 tsp vanilla
- 1 tsp gelatin + 2 tbsp cold water
Chocolate Glaze
- 150 g dark chocolate
- 120 ml (½ cup) hot heavy cream
- 1 tbsp butter
Instructions
Step 1 – Bake the Sponge
Preheat oven to 170°C / 340°F and line an 8-inch cake pan.
Sift together flour, cocoa, baking powder, baking soda, and salt. In another bowl, whisk eggs and sugar until pale and slightly thickened. Add milk, oil, vanilla, and dissolved coffee.
Gently fold the dry ingredients into the wet mixture. Pour into the prepared pan and bake 22–28 minutes, until set. Cool completely.
Step 2 – Prepare the Mousse
Bloom gelatin in cold water for 5 minutes.
Melt the chocolate gently and stir in the coffee mixture. Warm the gelatin until liquid and mix into the chocolate.
Whip cream with powdered sugar and vanilla to soft peaks. Fold into the chocolate in two additions until light and smooth.
Step 3 – Assemble
Keep the sponge in the pan or place it inside a cake ring. Pour mousse over the sponge and smooth the top.
Refrigerate at least 4 hours, preferably overnight, until fully set.
Step 4 – Add the Glaze
Pour hot cream over chocolate and add butter. Stir until smooth and glossy. Let cool slightly until thickened.
Pour glaze over the chilled cake and spread evenly. Refrigerate 30 minutes to set.
