Ingredients:
- 1 cup (125g) all-purpose flour
- ½ cup (50g) cocoa powder
- 1 tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt
- ¾ cup (150g) sugar
- 2 large eggs

- ½ cup (120ml) buttermilk or yogurt
- 1 tsp vanilla extract
- ½ cup (120ml) hot coffee or water

- Mix dry ingredients together.
- In another bowl, whisk eggs, sugar, oil, vanilla, and buttermilk.
- Combine wet and dry, then add hot coffee. Batter will be thin.
- Bake for 25–30 min. Cool completely and level the top if needed.
🍫 PART 2: Silky Chocolate Mousse
Ingredients:
- 200g (7 oz) dark chocolate, chopped
- 1½ cups (360ml) heavy cream, chilled
- 1 tsp gelatin + 2 tbsp water (optional for stability)
- 1 tsp vanilla extract
Instructions:
- Melt chocolate until smooth. Let cool slightly.
- If using gelatin, bloom it in water, then warm gently to dissolve.
- Whip cream to soft peaks.
- Stir a few tablespoons of cream into the chocolate to lighten.
- Gently fold chocolate into whipped cream along with vanilla (and gelatin if using).
- Chill until slightly firm but spreadable.
🍓 PART 3: Berry Filling or Compote
Option 1: Quick Compote
- 1½ cups mixed berries (raspberries, strawberries, blueberries)
- 2 tbsp sugar
- 1 tsp lemon juice
- Simmer for 5–7 minutes until thickened. Cool.
Option 2: Fresh Layer
- Use whole fresh berries (patted dry) — raspberries and blueberries work beautifully.
🎂 PART 4: Assembly
- Place chocolate cake layer in an 8-inch ring mold or springform pan.
- Spread a layer of chocolate mousse evenly.
- Spoon berry compote or scatter fresh berries over the mousse.
- Add another mousse layer to cover berries.
- Smooth top and chill for 4–6 hours or overnight.
🎨 PART 5: Abstract Finish (Choose One)
Option A: Whipped Cream Abstract Swirls
- Whip extra cream with a bit of powdered sugar.
- Tint portions with natural food coloring (e.g., berry, beet, cocoa).
- Dollop and swirl on top with an offset spatula for an artistic finish.
Option B: Mirror Glaze (Advanced)
- Use a white mirror glaze base and swirl in colored glazes for a marbled abstract effect.
- Pour over frozen mousse layer for a glossy, modern look.
Option C: Brushstroke Buttercream
- Use buttercream with a palette knife to create bold, modern swoops on the chilled cake surface.
✨ Decoration Ideas:
- Fresh berries, gold leaf, edible flowers, chocolate shards, or abstract chocolate curls.
- Add texture with a sprinkle of crushed freeze-dried berries or toasted nuts.
✅ Tips:
- Always chill mousse cakes before unmolding.
- Use acetate sheets for cleaner edges.
- For a taller cake, double the mousse and cake layers.
