Preheat oven to 180°C (350°F). Grease a small baking dish.
Gently separate and fluff the kataifi pastry with your fingers. Mix with melted butter or ghee until evenly coated.
Press half of the pastry into the base of the baking dish.
In a bowl, whisk ricotta, cream cheese, milk, and monkfruit until smooth and creamy. Spread this mixture evenly over the pastry base.
Cover with the remaining pastry and press lightly to seal.
