In a separate bowl, sift the flour, cocoa powder, and baking powder together to remove any lumps. Gradually add the dry ingredients into the egg mixture, gently folding them in until fully incorporated.
Pour the batter into the prepared baking tin and smooth it out. Bake for approximately 25 minutes or until a toothpick inserted into the center comes out clean. Once baked, remove from the oven and let cool completely.

2. Making the Meringue Layer:
Preheat the oven to 120°C (248°F).
In a clean, dry bowl, beat the 4 egg whites using an electric mixer until soft peaks form. Gradually add the sugar, beating continuously until stiff peaks form.
Add a pinch of citric acid to help stabilize the meringue.
Once the meringue is stiff and glossy, spread it evenly over the cooled cake base. Sprinkle the roasted walnuts on top.
Bake for about 60 minutes or until the meringue is firm and golden. Allow the meringue to cool completely after baking.
3. Preparing the Cream Filling:
In a saucepan, heat 100g of hot cream and 35g of butter together over low heat until the butter melts. Stir in the sugar until it dissolves completely.
Remove from heat and allow the mixture to cool slightly.
In a separate bowl, beat the remaining 200g of cream and 600g of cream cheese until smooth and creamy.
Once the butter and cream mixture has cooled, add it to the cream cheese mixture and beat until combined.
Spread the cream filling evenly over the cooled meringue layer.
