Instructions
1. Prepare the Sponge Cake
- Preheat your oven to 350°F (175°C).
- Grease and flour an 8-inch round cake pan.
- In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
- In a large mixing bowl, cream the softened butter and sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
- Gradually add the dry ingredients to the wet ingredients, alternating with the milk. Mix until just combined.
- Pour the batter into the prepared cake pan and smooth the top. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
- Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
2. Make the Caramel Mousse
- In a small saucepan, combine the granulated sugar and water over medium heat. Cook until the sugar dissolves and turns a deep amber color. Remove from heat and let it cool slightly.
- In a mixing bowl, beat the cream cheese until smooth. Gradually add the cooled caramel, mixing until well combined.
- In another bowl, whip the heavy cream until soft peaks form. Gently fold the whipped cream into the caramel mixture.
- In a small bowl, sprinkle the gelatin over the cold water and let it bloom for about 5 minutes. Then, heat it gently until dissolved. Stir the dissolved gelatin into the caramel mousse mixture until fully incorporated.
3. Assemble the Cake
- Once the sponge cake has cooled completely, slice it in half horizontally to create two layers.
- Place one layer of the sponge cake on a serving plate. Spread half of the caramel mousse over the top. Place the second layer of sponge cake on top and spread the remaining mousse over the top and sides of the cake.
- Cover the cake with plastic wrap and refrigerate for at least 4 hours or overnight to set.
4. Make the Caramel Sauce
- In a saucepan over medium heat, melt the sugar until it turns a deep amber color, stirring occasionally.
- Once melted, add the butter and stir until combined. Slowly pour in the heavy cream while stirring. The mixture will bubble, so be cautious.
- Stir in the sea salt and remove from heat. Allow to cool slightly.
5. Serve
- Once the cake is set, drizzle the caramel sauce over the top before serving. Slice and enjoy the delicious combination of flavors!
