Prep your cups: Line a muffin tin with 10–12 liners. For larger servings, use 10; for smaller bites, use 12.
Make the crust: In a bowl, mix graham crumbs, melted butter, maple syrup, and a pinch of salt until sandy and evenly moistened.
Press the base: Divide the crust mixture among the liners.
Press down firmly with the back of a spoon. Place the tray in the fridge while you make the filling.
Beat the cream cheese: In a large bowl, beat softened cream cheese until smooth and fluffy, about 1–2 minutes.
Add yogurt and flavor: Whisk in Greek yogurt, vanilla, lemon juice, and salt until silky.
Incorporate protein powder: Sift or sprinkle in protein powder gradually, mixing until no lumps remain. Taste and adjust sweetness with powdered sweetener.
Fill the cups: Spoon the filling over the chilled crusts, smoothing the tops with a spatula.
Tap the tray lightly to level.
Chill to set: Refrigerate for at least 2–3 hours, or until firm enough to peel away the liner cleanly. For best texture, chill 4+ hours.
Add toppings: Before serving, top with berries, a dusting of crumbs, nuts, or a light drizzle of honey.
Serve: Keep chilled until ready to eat. These are best cold for the creamiest bite.
