Wash 12 large strawberries under cool water, pat them dry, trim the stems, and slice them in half lengthwise. Scoop out a small portion of the center of each half.

In a large bowl, add 1 cup of cold heavy whipping cream and beat on medium-high speed until stiff peaks form, about 5 minutes.

In a separate bowl, mix 8 ounces of softened cream cheese, 1/2 cup sour cream, 1/4 cup sugar, 1 teaspoon vanilla, and optional lemon juice until smooth and creamy, about 2 minutes.

Gently fold one-third of the whipped cream into the cream cheese mixture, and then fold in the remaining whipped cream until well blended and fluffy.

Using a piping bag, fill each strawberry half with the cheesecake mixture, creating a nice swirl on top.

Sprinkle 1/4 cup of graham cracker crumbs on top of each filled strawberry, then arrange on a platter.
