Instructions

Step 1: Prepare the Chocolate Cake Base

Preheat your oven to 350°F (175°C). Grease and line a springform pan.
In a bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt.
Add eggs, milk, oil, and vanilla extract. Mix until smooth.
Slowly add hot water and stir until the batter is thin and well combined.
Pour into the prepared pan and bake for 20–25 minutes.
Let the cake cool completely in the pan.

Step 2: Make the Strawberry Puree

Blend strawberries, sugar, and lemon juice until smooth.
Strain the puree to remove seeds for a silky texture.

Step 3: Prepare the Gelatin

Sprinkle gelatin over cold water and let it bloom for 5 minutes.
Gently heat until dissolved (do not boil).
Stir into the strawberry puree and let it cool slightly.

Step 4: Make the Strawberry Mousse

Whip heavy cream until soft peaks form.
Gently fold the strawberry mixture into the whipped cream until smooth and airy.

Step 5: Assemble the Cake

Pour the strawberry mousse over the cooled chocolate cake base in the springform pan.
Smooth the top with a spatula.
Refrigerate for at least 4 hours (or overnight) until set.

Step 6: Prepare the Chocolate Ganache

Heat heavy cream until just simmering.
Pour over chopped chocolate and let sit for 2 minutes.
Stir until smooth and glossy.

Step 7: Finish the Cake

Pour ganache over the chilled mousse layer.
Tilt gently to spread evenly.
Chill for another 30–60 minutes until set.

Step 8: Garnish and Serve

Remove the cake from the springform pan.
Decorate with fresh strawberries and chocolate shavings.
Slice with a warm knife for clean, beautiful cuts.

Pro Tips for Perfect Results
