1. Whisk the sugar and cornstarch together with a fork until no lumps remain.

2. Add the sliced strawberries and lemon juice to a nonstick skillet or saucepan over low-medium heat.

3. Stir in the sugar and cornstarch mixture with a rubber spatula.

4. Cook gently, stirring often, for 10-15 minutes until the berries soften and the juices thicken enough to coat the back of the spatula.

5. Remove from heat and cool completely. To cool faster, transfer to a heatproof bowl and set it inside a larger bowl filled with ice.

6. In a large bowl using the whisk attachment, beat the cream cheese and powdered sugar until soft and smooth.

7. Remove the cream cheese mixture from the bowl, then beat the cold whipping cream in the same bowl until stiff peaks form.

8. Fold the whipped cream into the cream cheese mixture until evenly combined.

9. Line a 9×5 inch loaf pan with plastic wrap, leaving overhang on all sides. Line it in both directions so the pan is fully covered.

10. Make sure the strawberry compote is fully cooled. If it is very liquidy, strain it through a metal sieve and discard excess liquid.

11. Spoon about one-fourth of the cream filling into the bottom of the pan and smooth into an even layer.

12. Place a layer of graham crackers over the cream, breaking or cutting crackers as needed to cover the surface.

13. Spread about half of the strawberry compote over the graham crackers.

14. Spread about half of the remaining whipped cream filling over the berry layer.

15. Repeat with another layer of graham crackers, the remaining strawberry compote, another layer of whipped cream filling, and a final layer of graham crackers.

16. Cover the pan and chill in the fridge or freezer for at least 4 hours.

17. Before serving, optionally whip the additional ¼ cup whipping cream until medium peaks form.

18. Use the plastic wrap overhang to carefully lift the cake from the pan, then invert it onto a serving plate or cutting board.

19. Peel away the plastic wrap, top with whipped cream and sliced strawberries, then slice and serve.
