Prep the base (optional): If using a graham cracker crumb base, crush the cracker and lightly moisten with a few drops of melted light butter or a spritz of cooking spray.
Press it into the bottom of a small ramekin or a wide-mouth jar. This step is optional to keep calories near 100; the cup is great without it.
Soften the cream cheese: In a small bowl, microwave the light cream cheese for 5–10 seconds until just soft. You want it spreadable, not melted.
Mix the dairy: Add Greek yogurt to the cream cheese and whisk or beat with a fork until completely smooth.
No lumps is the goal here.
Add flavor and protein: Stir in protein powder, sweetener, vanilla, lemon juice (if using), and a pinch of salt. The mixture will be thick at first.
Adjust the texture: Add almond milk or water, about 1 teaspoon at a time, until you get a silky, pudding-like consistency. It should be scoopable, not runny.
Assemble: Spoon the mixture over the crust (if using) or directly into the ramekin.
Smooth the top with the back of a spoon.
Chill: Cover and refrigerate for at least 30–60 minutes. An hour gives the best cheesecake-like set, but even 20 minutes helps if you’re in a hurry.
Top and serve: Add a few berries, a tiny sprinkle of crumbs, or a light drizzle of sugar-free syrup. Enjoy cold.
