For crust: Use a food processor to crush your graham crackers. Stir in the sugar and melted butter. Press into the bottom of a baking dish or pie pan. Bake at 350° for about 10 minutes. Cool completely. Break into pieces.
Blueberry Sauce: Whisk together sugar and cornstarch in a medium saucepan. Whisk in water till smooth. Add orange juice concentrate and berries.
Cook over medium-high heat, stirring constantly. Bring to a boil and boil for 2 minutes, stirring. Cool completely.
Ice Cream Base: Beat cream cheese till smooth. Gradually beat in sugar till smooth and creamy. Whisk in cream, milk, vanilla, and lemon juice.
Chill crust, sauce, and ice cream base for several hours or till very cold. Freeze ice cream in an ice cream machine according to the manufacturer’s instructions.
Layer churned ice cream, blueberry mixture, and crust pieces into a freezer-safe container. Note: You will have some leftover sauce.
Freeze for 3-4 hours or till firm enough to scoop. Serve with additional blueberry sauce if desired.
Notes
You won't need all of the blueberry sauce. Set aside about 1/2 cup to serve with the ice cream, or save it for another use.
If you are short on time, you can substitute store-bought graham cracker crust and canned blueberry pie filling. I won’t judge.
