Prep the crust: In a bowl, mix graham crumbs, melted coconut oil or butter, maple syrup, and a pinch of salt. The mixture should look like damp sand and hold when pressed.
Portion the base: Line a muffin tin with paper liners or set out 6–8 small jars.
Spoon about 1–2 tablespoons of crust into each and press firmly with the back of a spoon. Chill for 10–15 minutes to set.
Make the strawberry layer: You have two options: Fresh and quick: Toss chopped strawberries with lemon juice and a little sweetener. Let them sit for 10 minutes to release juices.
Jammy topping: Simmer chopped strawberries with lemon juice and sweetener for 5–7 minutes until they soften. Stir in chia seeds and cool; it will thicken as it rests.
Whip the filling: In another bowl, beat cream cheese until smooth.
Add Greek yogurt, protein powder, sweetener, vanilla, lemon juice (if using), and salt. Whip until creamy and lump-free. Taste and adjust sweetness.
Assemble: Divide the cheesecake filling over the chilled crusts. Smooth the tops with a spoon.
Spoon strawberry layer over each cup.
Chill to set: Refrigerate for at least 1–2 hours, or until the cups are firm enough to hold their shape. Overnight is ideal for the best texture.
Finish and serve: Garnish with sliced strawberries. Serve chilled straight from the cups or remove liners for a handheld treat.
