1. Macerate the Strawberries:
- In a bowl, gently toss the sliced strawberries with 1/2 cup of the sugar.
- Set aside for about 30 minutes to allow the strawberries to release their juices.
2. Make the Cheesecake Filling:
- In another large bowl, beat the softened cream cheese, orange juice, and the remaining 1/2 cup of sugar with an electric mixer until smooth.
- Gently fold the whipped heavy cream into the cream cheese mixture until well combined. Set aside.
3. Prepare Cake and Berries for Layering:
- Drain the macerated strawberries, reserving the juice in a separate bowl. Set the drained berries aside.
- Gently toss the pound cake cubes with the reserved strawberry juice until lightly coated.
4. Assemble the First Layer:
- Place half of the juice-soaked cake cubes in the bottom of a 4-quart trifle dish or a large glass serving bowl.
- Top the cake with one-third of the cheesecake mixture.
- Layer half of the drained strawberries over the cheesecake mixture.
- Sprinkle half of the grated semisweet chocolate over the strawberries.
5. Assemble the Second Layer:
- Repeat the layers: Add the remaining cake cubes, followed by another third of the cheesecake mixture, the remaining drained strawberries, and the remaining grated chocolate.
6. Add the Final Topping:
- Top the trifle with the remaining one-third of the cheesecake mixture, spreading it smoothly.
7. Garnish (Optional):
- Garnish the top with chocolate curls and additional sliced strawberries, if desired.
8. Chill:
- Cover the trifle and refrigerate for at least 4 hours, or preferably overnight, to allow the flavors to meld and the trifle to set properly.
