In a medium bowl, combine graham cracker crumbs and melted butter. Press the mixture firmly into the bottom of a 9-inch pie plate or square baking dish.
In a large bowl, beat cream cheese until smooth. Gradually beat in sweetened condensed milk and vanilla extract until well combined.
In a separate chilled bowl, whip heavy cream with powdered sugar until stiff peaks form.
Gently fold whipped cream into the cream cheese mixture.
Fold in 3/4 cup of the crushed freeze-dried strawberries into the cream cheese mixture.
Pour the mixture over the prepared graham cracker crust.
Sprinkle the remaining 1/4 cup crushed freeze-dried strawberries over the top.
Cover and refrigerate for at least 2 hours to allow the cake to set.
Before serving, garnish with fresh strawberry slices, if desired.
Tips and Substitutions:
For a gluten-free option, use gluten-free graham crackers or a different type of gluten-free cookie for the crust.
Other freeze-dried fruits can be used in place of strawberries, such as raspberries or blueberries.
For a richer flavor, use a high-quality vanilla extract or vanilla bean paste.
The cake can be frozen for longer storage; thaw in the refrigerator before serving.
