What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and an indulgent texture without the fuss.

• For the Cake:
• 1 cup (120g) all-purpose flour
• 1/3 cup (40g) unsweetened cocoa powder
• 1 tsp baking powder
• 1/2 tsp baking soda
• Pinch of salt
• 3/4 cup (150g) granulated sugar
• 1/3 cup (80ml) vegetable oil
• 2 large eggs, room temperature
• 1 tsp vanilla extract
• 1/2 cup (120ml) milk, room temperature
• 1/2 cup (120ml) hot water
• For the Mousse:
• 8 oz (225g) semi-sweet chocolate, chopped
• 2 cups (480ml) heavy cream, divided
• 1/4 cup (50g) granulated sugar
• 1 tsp vanilla extract
• Optional Toppings:
• Chocolate shavings
• Fresh berries
• Whipped cream

If you need substitutions, try almond milk in place of regular milk for the cake, or dairy-free chocolate and coconut cream for the mousse.

Equipment Needed

• 9-inch round cake pan
• Mixing bowls
• Hand mixer or stand mixer
• Whisk
• Rubber spatula
• Baking parchment paper
• Double boiler or microwave-safe bowl
• Wire rack for cooling

If you don’t have a double boiler, don’t worry—just use a heatproof bowl over a pot of simmering water. For the cake pan, make sure it’s non-stick or line it with parchment paper to avoid any sticking issues.

Preparation Method

1. Preheat your oven to 350°F (175°C). Grease and line a 9-inch round cake pan with parchment paper.
2. In a large bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. Stir in the sugar and set aside.
3. In a separate bowl, whisk together the vegetable oil, eggs, vanilla extract, and milk. Gradually add the wet ingredients to the dry ingredients, mixing until just combined.
4. Carefully stir in the hot water (the batter will be thin—this is normal). Pour the batter into the prepared cake pan.
5. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
6. For the mousse, melt the chopped chocolate using a double boiler or microwave. Let it cool slightly.
7. In a mixing bowl, whip 1 cup of heavy cream with the sugar and vanilla extract until soft peaks form.
8. Gently fold the melted chocolate into the whipped cream until fully combined. Chill the mousse in the refrigerator for 30 minutes to firm up.
9. Once the cake has cooled, slice it horizontally into two even layers. Spread half of the mousse on the bottom layer, then place the top layer and cover with the remaining mousse.
10. Decorate with chocolate shavings, berries, or whipped cream as desired. Chill for at least 2 hours before serving for best results.

Cooking Tips & Techniques

Here are some tips to ensure your Chocolate Mousse Cake turns out perfectly:

• Use room temperature eggs: They mix more evenly and help create a smoother cake batter.
• Don’t overmix the mousse: Fold the whipped cream into the chocolate gently to maintain its airy texture.
• Cool the cake completely: A warm cake will melt the mousse, so patience is key here.
• Chill the mousse: Allowing the mousse to set in the fridge ensures a firmer texture that holds up well between the cake layers.
• Decorate just before serving: If using berries or whipped cream, add them later to keep them fresh.

Variations & Adaptations

• Gluten-Free Version: Swap the all-purpose flour for a 1:1 gluten-free baking flour.
• Dairy-Free Option: Use dairy-free chocolate and coconut cream for the mousse, and almond milk for the cake.
• Seasonal Twist: Add a layer of raspberry jam between the mousse and cake for a fruity touch.
• Nutty Flavor: Mix crushed hazelnuts into the mousse or sprinkle them on top for added crunch.

I’ve tried the raspberry jam variation myself, and it adds a refreshing tang that complements the chocolate beautifully!

Serving & Storage Suggestions

Serve this cake chilled or at room temperature for the perfect texture. Pair it with a cup of coffee or a glass of red wine to enhance the flavors. Fresh berries or mint leaves make excellent garnish options if you’re entertaining.

To store, cover the cake and keep it in the refrigerator for up to 3 days. You can also freeze individual slices for up to 2 months—just wrap them tightly in plastic wrap and place them in an airtight container. When reheating, allow frozen slices to thaw in the fridge overnight.
