Sponge Cake
Preheat the oven to 180°C.
Mix flour, sugar, cocoa, baking powder, baking soda, and salt.
Add eggs, oil, milk, and vanilla. Mix well.
Add the hot water little by little (the batter will be runny).
Pour into two greased round pans and bake for 30–35 minutes.
Let cool completely.
Cream Filling
Whip the cold cream with the powdered sugar and vanilla until stiff peaks form.
Spread between the cake layers.
