Instructions

1. Prepare Dry Ingredients

   In a mixing bowl, whisk together the sifted flour, baking powder, baking soda, and granulated sugar until evenly combined.

   Time: PT2M

2. Make Cocoa Mixture

   Combine warm water and cocoa powder in a small bowl. Whisk for 20‑30 seconds, let rest a few seconds, then whisk again for another 20‑30 seconds until smooth.

   Time: PT2M

3. Cream Butter and Sugar

   Add the softened butter to the dry‑ingredient bowl. Using the whisk, beat until the mixture looks crumbly, then add the sugar and whisk until the sugar is lightly incorporated.

   Time: PT3M

4. Add Eggs and Cocoa Mixture

   Crack the two eggs into the bowl, then pour in the cocoa mixture. Whisk for about 20‑30 seconds, pause, then whisk again for another 20‑30 seconds. Finish with a final quick whisk to achieve a smooth batter.

   Time: PT5M

5. Bake the Cake

   Preheat the oven to 175°C (350°F). Grease the 8‑inch round pan, pour in the batter, and smooth the top. Bake for 25‑30 minutes, or until a toothpick inserted in the center comes out clean.

   Time: PT30M

   Temperature: 175°C

6. Cool and Invert the Cake

   Allow the cake to cool in the pan for about 10 minutes. Then, using a plate or a clean kitchen towel, carefully turn the pan upside down so the cake releases onto the plate. Let it cool completely before adding the mousse.

   Time: PT10M

7. Melt Chocolate for Mousse

   Break 150 g of dark chocolate into pieces and melt it with a splash of hot water in a saucepan over low heat, stirring until smooth. Set aside to cool slightly.

   Time: PT5M

8. Whisk Heavy Cream

   In a clean bowl, whisk the cold heavy cream for about 30 seconds until it begins to thicken but is still soft.

   Time: PT1M

9. Combine Chocolate and Cream

   Gradually pour the slightly cooled melted chocolate into the whipped cream while whisking continuously. Continue whisking until the mixture becomes thick, glossy, and holds soft peaks – this is the chocolate mousse.

   Time: PT4M

10. Spread Mousse Over Cake

    Using a spatula, spread the chocolate mousse evenly over the cooled cake, smoothing the top and sides.

    Time: PT5M

11. Chill the Assembled Cake

    Place the mousse‑topped cake in the refrigerator and chill for at least 1 hour to set the mousse.

    Time: PT1H

12. Prepare Chocolate Glaze

    Melt the remaining 150 g of dark chocolate with a splash of hot water, stirring until smooth. Drizzle the glaze over the chilled mousse cake, allowing it to drip down the sides.

    Time: PT5M

13. Serve

    Slice the cake with a sharp knife warmed in hot water for clean cuts. Serve chilled.

    Time: PT2M
