Timing

Step-by-Step Instructions
1. Prepare the Chocolate Cake
- Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour a heart-shaped cake pan.
- Mix Dry Ingredients: In a mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- Combine Wet Ingredients: In another bowl, mix the softened butter, eggs, vanilla extract, and buttermilk until well combined.
- Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, mixing until just combined.
- Bake: Pour the batter into the prepared heart-shaped cake pan and bake for 25-30 minutes, or until a toothpick inserted comes out clean. Allow the cake to cool completely in the pan before removing.
2. Prepare the Raspberry Mousse
- Bloom Gelatin: In a small bowl, sprinkle the gelatin powder over the cold water and let it sit for about 5 minutes to bloom.
- Heat Gelatin: Gently heat the bloomed gelatin in the microwave for about 10 seconds until dissolved. Stir in the raspberry puree and sugar until well combined.
- Whip Cream: In a separate bowl, whip the chilled heavy cream until soft peaks form. Gently fold the raspberry mixture into the whipped cream until fully incorporated.
3. Assemble the Cake
- Layer Mousse: Once the chocolate cake has cooled, slice it in half horizontally to create two layers. Place one layer on a serving plate.
- Add Mousse: Spread half of the raspberry mousse over the first layer of cake. Place the second layer on top and spread the remaining mousse over the top and sides of the cake.
4. Chill the Cake
- Chill: Cover the cake with plastic wrap and refrigerate for at least 1 hour to allow the mousse to set.
5. Serve
