Ingredients

Scale

Cake Ingredients

  • 1 cup all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1 cup granulated sugar
  • 1 tsp baking powder
  • 2 large eggs
  • 1/2 cup vegetable oil
  • 1/2 cup whole milk

Mousse Ingredients

  • 1 cup fresh raspberries
  • 1 cup dark chocolate chips
  • 1 tsp agar-agar powder

Instructions

  1. Preheat and prepare pans: Preheat your oven to 350°F (175°C). Grease two round cake pans thoroughly to prevent sticking and ensure easy removal of the cakes after baking.
  2. Mix dry ingredients: In a large bowl, sift together the all-purpose flour, unsweetened cocoa powder, granulated sugar, and baking powder. Whisk until evenly combined to create a uniform dry mix.
  3. Combine wet ingredients: In another bowl, beat the eggs, vegetable oil, and whole milk until the mixture is frothy. Gradually add this to the dry ingredients and stir gently until just combined—avoid overmixing to keep the cake light and fluffy.
  4. Bake the cakes: Divide the batter evenly between the two prepared cake pans. Bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean. Remove from oven and allow cakes to cool completely in the pans before removing.
  5. Prepare the raspberry chocolate mousse: Gently melt the dark chocolate chips until smooth. Separately, heat the fresh raspberries with the agar-agar powder until the agar-agar fully dissolves, creating a thickened raspberry gel. Fold the melted chocolate into the raspberry mixture, stirring gently to combine into a smooth mousse.
  6. Assemble the cake: Place one cake layer on a serving plate. Spread half of the raspberry chocolate mousse evenly over the top. Carefully place the second cake layer on top, and finish by spreading the remaining mousse on the top of the cake for a sumptuous finish.

Notes

  • Ensure the cakes are completely cool before applying the mousse to prevent melting.
  • Agar-agar powder acts as a vegetarian gelatin substitute; adjust quantity slightly if using another setting agent.
  • For a more intense chocolate flavor, use high-quality dark chocolate chips.
  • Fresh raspberries add brightness, but frozen raspberries can be used if fresh are not available—thaw and drain excess liquid first.
  • Store the assembled cake in the refrigerator to keep the mousse set and fresh.
