In a mixing bowl, combine the softened cream cheese, powdered sugar, and vanilla extract. Beat with an electric mixer until smooth and creamy.
In a separate bowl, whip the heavy cream until stiff peaks form.
Carefully fold the whipped cream into the cream cheese mixture until well incorporated, creating a smooth and fluffy dip.
In a small bowl, mix the diced strawberries with lemon juice. Gently fold the strawberries into the cheesecake dip, making sure not to break them up too much.
Transfer the dip to a serving bowl and top with additional diced strawberries and a sprinkle of graham cracker crumbs.
Optionally, chill in the refrigerator for 30 minutes to enhance the flavors before serving.
