To make the muhallebi for the magnolia dessert, add the milk, sugar, cream, flour and egg to a small pot and cook while stirring. Once cooked, add the vanilla and leave it to cool. In another bowl, crush the biscuits and hazelnuts with a blender. Press the ready mixture firmly into the bottom of the dishes you will serve in and pour the muhallebi over it. Arrange the strawberry slices in a row, pressing them against the sides of the dish. Repeat these steps twice and at the very end you can decorate the top with strawberries and serve. Enjoy your meal!
