Prep the strawberries: In a bowl, toss sliced strawberries with granulated sugar and lemon juice. Let sit 15–20 minutes until the juices release.
If you like a stronger strawberry flavor, stir in the jam.
Make the cream layer: Beat the cream cheese with powdered sugar, vanilla, and a pinch of salt until smooth. In a separate bowl, whip the heavy cream to medium peaks. Fold the whipped cream into the cream cheese mixture until fluffy and uniform.
Cube the cake: Cut the angel food cake into bite-size cubes.
Keep pieces fairly even so the layers look neat.
Layer the trifle: In a clear trifle dish or large glass bowl, add a layer of cake cubes. Spoon over some strawberries with a little of their juice. Add a layer of the cream mixture, spreading gently to the edges.
Repeat: Continue layering cake, strawberries, and cream until you reach the top.
Aim for 3–4 layers, finishing with cream.
Garnish: Top with a few whole or halved strawberries. Add mint if you like a fresh pop of color.
Chill: Cover and refrigerate for at least 1 hour (and up to 8) so the flavors meld. Serve chilled.
