Mix crushed biscuits with melted butter until evenly combined.
Divide the biscuit mixture equally among the four compartments of your silicone container and press down firmly.
In a bowl, beat cream cheese until smooth.
Add Greek yogurt, powdered sugar, vanilla extract, and mango puree.
Mix until creamy and lump-free.
Spoon the filling evenly over the biscuit base.
Smooth the tops with a spatula.
Cover with the lid and refrigerate for at least 4 hours, or freeze for a firmer dessert.
Garnish with fresh mango cubes and mint before serving.
