- 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.
