To make the blueberries: In a small saucepan, bring 2 tablespoons water, the sugar, and lemon juice to a simmer over medium heat, stirring occasionally to dissolve the sugar. Add the blueberries and cook, stirring often, until they soften, 1 to 2 minutes (a little longer if using frozen berries). Use a fork to gently mash most of the berries, then turn off the heat.
To make the cheesecake pudding: Whisk the sugar, cornstarch, and salt together in a medium saucepan. Whisk in the cold milk and then set the saucepan over medium-high heat. Continue to whisk until a few bubbles pop at the surface and the mixture is thick, 3 to 4 minutes. Turn off the heat and whisk in the vanilla and the cream cheese.
Divide half the pudding among 4 ramekins, then divide the blueberries among the ramekins. Top each serving with the remaining pudding. Cover each ramekin with plastic wrap and refrigerate for at least 4 hours or up to 3 days. Serve chilled, sprinkled with graham crumbs.
