Preheat your oven to 180°C (350°F). Grease and flour a cake pan to ensure the cake comes out easily after baking.
Prepare the sponge mixture: In a large mixing bowl, beat the eggs and sugar together until the mixture becomes light and fluffy. This will take about 5-7 minutes.
Add the dry ingredients: Sift together the wheat flour, baking cocoa, and baking powder, then fold them gently into the egg mixture until just combined. Be careful not to over-mix!
Bake the cake: Pour the batter into the prepared cake pan and bake for about 25-30 minutes, or until a toothpick inserted into the center comes out clean. Allow it to cool in the pan for about 10 minutes before transferring it to a wire rack.
Make the whipped cream: In another bowl, whip the cream with cream stiffener and vanilla sugar until stiff peaks form.
Assemble the cake: Once the sponge is completely cool, spread the whipped cream generously on top of the cake.
Top with cherries: Decorate the cake with fresh cherries for a vibrant finish.
Serve and enjoy: Slice the cake and serve it to your delighted guests!
