I love this chocolate mousse for cake (no gelatin or eggs)

Ingredients

• 200 g Dark Chocolate (70‑72% cacao) (chopped into 1‑2 cm pieces; use Trader Joe’s or similar)
• 30 g Unsalted Butter (cut into small cubes)
• 1 pinch Pinch of Salt (enhances chocolate flavor)
• 500 ml Heavy Whipping Cream (cold, 36% fat; divided 300 ml for mousse, 200 ml for outer frosting)
• 120 g Full‑Fat Sour Cream (adds richness and slight tang to mousse)
• 30 g Powdered Sugar (for sweetening the outer whipped cream)
• 0.25 tsp Azana Stiff (modified corn starch stabilizer) (adds stability to whipped cream without flavor; use only a quarter‑teaspoon)
• 4 pieces 8‑inch Chocolate Chiffon Cake Rounds (pre‑baked, sliced horizontally into thin layers)
• 5 leaves Fresh Mint Leaves (optional garnish) (adds fresh aroma; substitute thyme if unavailable)

Instructions

1. Prepare Chocolate Base

   Chop the dark chocolate into roughly 1‑2 cm pieces and place them in a microwave‑safe bowl with the butter and a pinch of salt.

   Time: PT5M

2. Melt Chocolate and Butter

   Microwave on high for 20‑second intervals, stirring between each, until the mixture is glossy and fully melted (about 40 seconds total).

   Time: PT2M

   Temperature: High power microwave

3. Chill Whipping Bowl

   Place a separate mixing bowl and the whisk attachment in the freezer for about 5 minutes.

   Time: PT5M

4. Whip Cream for Mousse

   Remove the chilled bowl, add 300 ml heavy whipping cream and whip on medium speed until soft peaks form.

   Time: PT5M

5. Combine Chocolate with Whipped Cream

   Re‑warm the melted chocolate for 10‑second bursts until it is still warm but not hot, then slowly fold it into the whipped cream until fully incorporated, creating a smooth mousse base.

   Time: PT5M

   Temperature: Warm (≈40‑45°C)

6. Add Sour Cream

   Stir in the full‑fat sour cream until the mousse is uniform and slightly glossy.

   Time: PT2M

7. Chill Mousse Briefly

   Transfer the mousse to a clean bowl, cover, and refrigerate for about 5 minutes to firm slightly for easier handling.

   Time: PT5M

   Temperature: Refrigerator (4°C)

8. Slice Cake Layers

   Using a long serrated knife, slice each 8‑inch chiffon cake round horizontally into two thin layers, yielding four layers total.

   Time: PT5M

9. Assemble Cake with Mousse

   Place the first cake layer on a turntable, spread ~¼ cup of mousse evenly with a spatula, then top with the next layer. Repeat until all four layers are stacked with mousse between each.

   Time: PT10M

10. Chill Assembled Cake

    Cover the assembled cake and refrigerate for at least 30 minutes to let the mousse set fully.

    Time: PT30M

    Temperature: Refrigerator (4°C)

11. Whip Outer Cream

    Remove the chilled bowl, add the remaining 200 ml heavy cream, a pinch of sugar, and the measured ¼ tsp Azana Stiff. Whip on low speed until thick, then increase to medium until soft peaks form.

    Time: PT7M

12. Apply Crumb Coat

    Spread a thin layer of whipped cream over the entire cake to lock in crumbs. Chill for 10 minutes.

    Time: PT10M

    Temperature: Refrigerator (4°C)

13. Final Frosting

    Using a bench scraper and spatula, apply a generous layer of whipped cream over the sides and top, smoothing with the acrylic disc for a flawless finish. Patch any holes or gaps as needed.

    Time: PT12M

14. Garnish (Optional)

    Scatter fresh mint leaves (or thyme) over the top for aroma and visual appeal.

    Time: PT2M
