  • ½ cup sugar
  • 1 tablespoon gelatin
  • 2 tablespoons water
  • 1 teaspoon vanilla extract
  • ½ cup finely chopped pistachios (plus extra for garnish)

• For the Cake:

  • 1 cup all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ½ cup unsalted butter, softened
  • 1 cup sugar
  • 2 large eggs

Step-by-Step Instructions

Step 1: Prepare the Gelatin

In a small bowl, sprinkle the gelatin over the water and let it bloom for about 5 minutes.

Step 2: Make the Cake

1. Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round baking pans.
2. In a large bowl, beat the softened butter and sugar together until light and fluffy, about 3 minutes.
3. Add eggs one at a time, mixing well after each addition. Stir in almond milk and vanilla extract.
4. In another bowl, whisk together flour, baking powder, baking soda, and salt. Gradually incorporate the dry ingredients into the wet ingredients until just combined.
5. Divide the batter evenly between the two prepared pans and bake for 20-25 minutes. A toothpick inserted in the center should come out clean.
6. Allow the cakes to cool in the pans for 10 minutes before transferring to wire racks.

Step 3: Prepare the Mousse

1. In a blender, puree the raspberries until smooth, and strain to remove seeds.
2. In a saucepan, heat the raspberry puree over medium heat, then stir in the bloomed gelatin until dissolved. Remove from heat and let it cool slightly.
3. In a separate bowl, whip the heavy cream and sugar together until stiff peaks form. Gently fold in the raspberry mixture and chopped pistachios.

Step 4: Assemble the Cakes

1. Once the cakes are completely cooled, level the tops if they have domed.
2. Place one cake layer on a serving plate, spread a layer of mousse on top, and then add the second cake layer on top.
3. Spread the remaining mousse over the top and sides of the cake, then garnish with extra pistachios.

Common Mistakes to Avoid

1. Not Blooming the Gelatin: Ensure your gelatin is fully bloomed before adding it to the mousse for the right thickness.
2. Overmixing the Batter: Be gentle when incorporating the dry ingredients to avoid dense cake layers.
3. Skipping the Cooling Step: Letting your cakes cool completely before frosting is crucial for avoiding a runny mousse.

Storing Tips for the Recipe

• Short-term: Keep leftovers in the fridge for up to 3 days in an airtight container.
• Long-term: For longer storage, freeze the mousse layers separately, wrapped well, for up to a month. Thaw before assembly.
