In a mixing bowl, mix together graham cracker crumbs, melted butter, and sugar.
Line an 8x8" baking pan with wax paper or parchment paper, leaving some extra hanging over the sides of the pan for easy removal.
Press the graham crackers into the bottom of the pan.
Place the pan in the freezer for 15-30 minutes or until crust is set and cooled down.
In a blender, add cream cheese, sugar, strawberries, and vanilla. Blend until mixture is smooth and creamy.
In a mixing bowl, whip the whipping cream until soft peaks form (it will take a few minutes - I beat mine with an electric hand mixer).
Folding whipping cream into the creamy strawberry mixture.
Pour strawberry mixture into chilled crust. Spread over crust so that strawberry mixture is smooth and even.
Cover pan and freeze for 4-6 hours or even overnight.
When ready to serve, remove pan a few minutes before cutting. Top bars with fresh strawberries and more whipped cream, if desired.
Place leftovers back into the fridge.
