Prepare the cake batter: Beat together sugar, eggs, vanilla, and salt very well until reaching the ribbon stage, where the mixture falls in one piece from the whisk.
Add dry ingredients: Gently mix in flour, baking powder, and raw cocoa powder at the lowest speed until the batter is smooth and well combined.
Bake the cake: Pour the batter into a 30x40 cm tray greased with margarine and dusted with flour. Bake in a preheated oven at 180°C (356°F) on the middle rack until done (about 20-25 minutes). Then cool and peel the cake.
Make the syrup: Mix one large spoon of raw cocoa, two large spoons of honey, and half a cup of boiling water until well combined. Use this to drizzle over the cooled cake.
Prepare the Chantilly cream: Beat two packets of Dream Chantilly cream with one cup of iced milk until light, fluffy, and firm enough to hold shape.
Assemble the cake: Cut the cake in half horizontally. Spread Chantilly cream on one half, add chopped strawberries, then place the other half on top. Use a hot knife dipped in boiling water to cut clean edges.
Decorate: Grate chocolate over the top layer, cut the cake into 16 pieces by dividing lengthwise and widthwise, then arrange on a serving tray. Pipe roses using Chantilly cream and decorate with cherries.
