Shave your [semi-sweet chocolate] bar over the top using a vegetable peeler. It looks like little chocolate curls! We like to add a few fresh cherries on top just to make it look extra fancy for our guests
In a saucepan, cook cherries, reserved syrup, sugar, and cornstarch over medium heat until thick and glossy. Cool completely.
Stir Kirsch or cherry juice into the cooled cherry compote. Drizzle a little over the cake cubes if desired.
Whisk chocolate pudding mix with cold milk for 2 minutes. Chill for 5 minutes to set.
Beat whipping cream, powdered sugar, and cream cheese until stiff peaks form.
Layer half the cake, cherries, pudding, and whipped cream in the trifle bowl. Repeat layers.
Shave chocolate over the top and garnish with cherries if desired. Chill at least 4 hours before serving.
