Make the Cream: In a saucepan, combine milk, honey, cornflour, vanilla, egg yolks, and a pinch of salt. Mix quickly and cook over medium heat, stirring constantly, until the mixture thickens.
Add Cream Cheese: Remove the saucepan from the heat and add cream cheese. Stir until the cream cheese is fully incorporated and the mixture is smooth.
Cool the Cream: Transfer the cream to a baking tray and cover with cling film, pressing the film down on the cream to prevent a skin from forming. Refrigerate until cool, more than two hours.
Prepare for Assembly: Remove the cream from the refrigerator and beat in a mixer for 1 minute to fluff up.
Assemble the Trifle: In a large glass deep container, add a layer of granola, followed by a layer of cream, and then a layer of strawberry jam. Repeat the layering process two more times.
Final Touches: Freeze the assembled trifle in the refrigerator before serving.
