Make the Crust: Mix graham cracker crumbs, melted butter, and sugar until combined. Press firmly into the bottom of a 9-inch springform pan. Freeze while preparing filling.
Prepare the Berry Puree: Blend berries, sugar, and lemon juice until smooth. Strain to remove seeds if desired.
Make the Filling: Beat cream cheese, powdered sugar, and vanilla until smooth. Fold in whipped cream until fluffy. Divide mixture in half; stir berry puree into one half.
Assemble: Spread plain cheesecake mixture over crust. Dollop berry mixture on top and swirl gently with a knife for a marbled effect.
Freeze: Cover tightly with plastic wrap or foil and freeze at least 360 minutes (or overnight) until firm.
Serve: Let sit at room temperature for 10 minutes before slicing. Garnish with extra berries, berry sauce, or whipped cream.
Notes
For best flavor, use fresh, ripe berries. Allow cheesecake to sit at room temperature before slicing for clean cuts.
