Step-by-Step Instructions:
Prepare the Chocolate Cake Base:
- Preheat your oven to 350°F (175°C). Grease and flour a 9-inch springform pan.
- In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt.
- In a separate medium bowl, whisk together the warm water, vegetable oil, vinegar, and vanilla extract.
- Pour the wet ingredients into the dry ingredients and whisk until just combined. Do not overmix.
- Pour the batter into the prepared springform pan. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
- Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely. Once cooled, place the cake back into the cleaned springform pan.
Prepare the Caramel Sauce:
- In a medium saucepan, combine the 1 cup of granulated sugar and ¼ cup of water.
- Heat over medium heat, stirring until the sugar dissolves.
- Once dissolved, stop stirring and allow the mixture to simmer. Watch it closely as it will begin to turn amber. This can take 8-12 minutes. Swirl the pan gently if needed for even coloring.
- Once it reaches a deep amber color, carefully whisk in the warmed heavy cream. The mixture will bubble vigorously. Stir until smooth.
- Remove from heat and whisk in the butter and sea salt until fully incorporated.
- Set aside to cool slightly. You will need 1 cup of this for the mousse, and the rest can be saved for drizzling.
Prepare the Caramel Mousse:
- In a small bowl, sprinkle the gelatin powder over the ¼ cup of cold water. Let it bloom for 5-10 minutes until it becomes jiggled and thickened.
- In a large bowl, beat the softened cream cheese with an electric mixer until smooth.
- Add the powdered sugar and ½ cup of the cooled caramel sauce (ensure it’s not too hot, or it will melt the cream cheese) and beat until well combined and creamy. Stir in the vanilla extract.
- Gently heat the bloomed gelatin mixture in the microwave for about 10-15 seconds, just until it liquefies. Be careful not to overheat.
- Pour the liquefied gelatin into the cream cheese mixture and beat until thoroughly incorporated.
- In a separate chilled bowl, whip the 1 ½ cups of chilled heavy cream until stiff peaks form.
- Gently fold about one-third of the whipped cream into the cream cheese mixture to lighten it, then carefully fold in the remaining whipped cream until no streaks remain and the mousse is light and airy.
Assemble the Decadent Caramel Mousse Cake:
- Pour the prepared caramel mousse evenly over the cooled chocolate cake base in the springform pan.
- Smooth the top with an offset spatula.
- Cover the springform pan tightly with plastic wrap and refrigerate for at least 4-6 hours, or preferably overnight, until the mousse is fully set.
Garnish and Serve:
- Once the mousse is set, carefully remove the sides of the springform pan.
- Drizzle with extra caramel sauce, top with whipped cream, chocolate shavings, or sea salt flakes as desired.
- Slice and serve chilled.
