How to Make Chocolate Mousse Cake

1. Prepare Cake: Preheat your oven to 350 °F (175 °C). In a mixing bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. In another bowl, beat the egg with granulated and brown sugar along with the oil. Gradually add the flour mixture and milk, alternating between the two, until just combined. Pour into a prepared cake pan and bake for 30-32 minutes, checking with a toothpick until it comes out clean. Cool the cake on a wire rack.

2. Make Mousse: Begin melting the dark chocolate with a small amount of simmered cream over low heat, stirring until smooth. Allow it to cool slightly. Meanwhile, whip the remaining cream in a separate bowl until soft peaks form. Gently fold the whipped cream into the cooled chocolate until no streaks remain. Line the edges of your cooled cake with halved strawberries and fill with the mousse, smoothing the top as you go. Chill in the refrigerator for at least 4 hours.

3. Prepare Ganache: To create the ganache, heat cream in a saucepan until it starts bubbling. Remove from heat and pour over chopped chocolate, letting it sit for a minute before stirring until smooth. Let the ganache cool slightly before spreading it over the chilled mousse layer. Chill again for approximately 30 minutes to set before serving.

4. Serve: When ready to serve, decorate your cake with fresh strawberries on top. Use a warm knife to slice for clean cuts, revealing those delicious layers!

Optional: Dust the top with cocoa powder for an elegant finish.
