Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a mixing bowl, beat the eggs and granulated sugar until thick and pale. Add vanilla extract and mix.
Sift together the flour, cocoa powder, baking powder, and salt. Gently fold into the egg mixture.
Pour the batter onto the prepared baking sheet and spread evenly. Bake for 15 minutes.
Dust a clean kitchen towel with powdered sugar. Once baked, invert the cake onto the towel and roll it up with the towel. Let it cool.
For the filling, whip the heavy cream with powdered sugar and vanilla extract until soft peaks form. Fold in the chopped cherries and kirsch or cherry juice.
Unroll the cooled cake carefully and spread the filling evenly over it. Roll the cake back up without the towel.
For the ganache, heat the heavy cream until just boiling. Pour it over the chopped chocolate and butter. Stir until smooth.
Drizzle the ganache over the rolled cake. Decorate with whipped cream, whole cherries, and chocolate curls if desired.
Notes
For a richer flavor, use dark chocolate for the ganache. You can also add more cherries for a fruitier filling.
